> Full release history of dsh-better-sidebar (see the [README](README_EN.md) for the latest release; also mirrored on [GitHub Releases](https://github.com/omdsh-dev/DSH-better-sidebar/releases)).

### v0.20.0 (dev line, **never published**)

> 🚫 **This version never reached npm** (npm `latest` is still v0.19.1): it was meant to be the stable release on the 0.1.6-alpha.2 line, but the 0.21 line replaced it before release, so everything below actually shipped in **v0.21.1**. Its original positioning: supports **DSH 0.1.6-alpha.2+** only (peer floor `^0.1.6-alpha.2`, CI pins `@deepseek-ai/dsh@0.1.6-alpha.2`). **This is a breaking-change release**: hosts on 0.1.5-rc.* should pin `dsh-better-sidebar@0.19.1`. See [docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md](docs/plans/2026-09-21-dsh-0.1.6-alpha.2-adaptation.md) for the adaptation record.

- 🖥️ **Terminal handed to DSH's built-in**: DSH 0.1.6 ships its own right-column terminal (`ui-sidebar-terminal`), so the plugin deleted its whole terminal stack — `pty-manager` / `agent-pty` / `pty-deps` / the 8 `terminal_*` tools / the xterm view and font-linking / cross-session terminal pinning — along with the `node-pty` dependency, its `allowBuilds` grant and the installer's `-Repair` mode. **Note**: the model therefore loses a cross-call persistent terminal (only one-shot `bash` / `pwsh` remain); the upstream `@deepseek-ai/dsh-tool-terminal` is not mounted by any shipped bundle, so enable it yourself in the profile when you need it.
- 🌐 **Browser view handed to the built-in**: the plugin deleted `BrowserView` / the sandbox status bar / the embeddability probe (including the host's `browser.probe` route) and the two settings that only configured its own iframe; it **keeps** the external-link takeover in the chat and UI (protocol-based routing is the capability the host does not have), now targeting DSH's built-in `browser` tab type.
- 🧩 **The produced-files row goes back to the host**: DSH 0.1.6 turned `conversation.chat.turnTail` from a chain into a list (upstream deliberately lets several plugins **append** rather than replace each other), so the plugin's takeover could only duplicate the built-in deliverables card and was removed wholesale; click behaviour is unchanged (the built-in goes through the host's `openFile` → this plugin's editor). The cost is the one "reveal in the file tree" entry at the turn tail (the in-tree context menu remains).
- 🐛 **Two silent breakages fixed**: once `SidebarRightGuideEntry.id` became required, a missing id left the **whole native surface silently empty** (the throw happens inside an `ctx.inject` callback and is swallowed); once `turnTail` became a list the old registration threw outright and the row died. Both are fixed and guarded by tests, with a registration-failure reporting hook added alongside.
- 🎨 **The empty-pane card now matches the built-in card recipe**: `.paneCard` adopts DSH's guide-capsule recipe (0.5px l4 border / 24px radius / layer-1 fill / 56px minimum / 14×20 padding), with tests guarding its geometry, its tokenized colours, and that it does not copy upstream's **undefined** `--dsw-alias-bg-l1/-l2` spellings.
- 📐 **Baseline**: every `@deepseek-ai/dsh-*` package is pinned to `0.1.6-alpha.2`, the vanished `dsh-code-runtime` package is removed, `diff` / `simple-icons` are hoisted into devDependencies as primitives' new bare imports, and `ui-primitives`' three breakages this release (`IconSendOutline16` gone, `TerminalBlockLabels.noExitCode` added, `ConnectionIndicator.reconnectLabel` removed) are adapted.

### v0.19.1

> 📌 **Stable release** (npm `latest`, no prerelease suffix): the pinned baseline moves to **DSH 0.1.5-rc.2** (npm `next`) while the **peer floor stays `^0.1.5-rc.1`** — nothing in the rc.2 upstream delta touches this plugin (zero changes under `packages/api|host|session|agent`; the only real code edits are the message-feedback dialog, deliverables card CSS and the `CodeFileIcon` SVG data split), so rc.1 hosts need no DSH upgrade to run this version. Hosts on DSH 0.1.5-alpha.2 stay on **v0.19.0-alpha.1**; the 0.1.2-rc.1 stable line keeps using **v0.18.1**.

- 🎯 **Adapted to DSH 0.1.5-rc.2**: devDependency pins, the CI mount lane and `SIDEBAR_SERVICE_VERSION` all move to rc.2; there is **no plugin-side code change** (the upstream delta does not touch this plugin — file-by-file audit in [docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md](docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md): the vast majority of the 300 changed files are single-line `version` bumps).
- 🎨 **File icons (#611) and the built-in tab glyphs are now colored** (#531 + #594 merged, implementation redone for rc.2):
  - **Files and folders use DSH's own artwork**: the fallback link is the host's `FileTypeIcon` from `ui-primitives` (48 full-color official code/config glyphs plus the category-colored sheets for markdown, images, PDF, Office, video and folders), so the plugin **ships no extension table and needs no icon chunk** — #429's 563-entry color dataset and `lib/client-file-icons.js` (255 kB) are gone, along with the `fileIconTheme` switch. Color is simply the behaviour now, and the core bundle grew by 10 kB.
  - **New public `registerFileIcon` API** (capability `'fileIcons'`): register your own glyphs by extension (`exts`), exact file name (`names`) or directory name (`folderNames`), ranked by priority then registration order. **Caveat**: the host classifier covers every path, so a catch-all (`exts: []`) claims every row the specific rules miss.
  - **Colored built-in tab glyphs**: Files / Changes / Tasks / Side chat / Terminal / Browser and the diff view all get a colored glyph, painted from `--dsw-alias-*` tokens so every skin still applies.
  - **The native right Sidebar's tab chips carry a glyph too**: the host's tab definition has no icon field, but the `sidebar.right.pane.tab.title` slot *is* the chip's content — the plugin renders `[glyph][title]` there (an editor tab with a path shows that file's icon). The glyph is `aria-hidden`, so the chip's accessible name is unchanged.
- 🛠 **CI fix 1: real Windows-lane timeouts**. `ci-windows` went red eight times in the 2026-09-09/10 window; six of those were process-spawning cases hitting vitest's 5000 ms default: `tests/agent-pty.spec.ts` (real PowerShell + ConPTY per terminal) and `tests/install-powershell.spec.ts` (a cold `powershell.exe` start measured 12.1 s) now declare a 30 s budget each, vitest.config.ts raises the global `testTimeout` from its 5000 ms default to **15 s** (the first real Windows run then lost a *third* file to the same default — `tests/git.spec.ts:85` at 9607 ms; three files, one cause, so per-file patches were whack-a-mole), and `waitForTranscript`'s inner poll budget dropped from 5000 ms to 15 s — **the inner budget must sit below the outer one** (they used to be the same 5000 ms, a structurally guaranteed timeout). `ci-windows`'s `Test` step now runs `pnpm test:windows` (`--maxWorkers=2`) so the process-spawning specs stop starving each other on a 2-core runner.
- 🛠 **CI fix 2: the mount lane's npm install**. `plugin-mount`'s `npm install -g @deepseek-ai/dsh@<ver>` failed four times (two `ETARGET`, two `JavaScript heap out of memory` / exit 134): the pinned version declares its transitives as floating `^` ranges, so while upstream publishes a prerelease in stages (rc.2 appeared package by package between 14:43 and 14:57 UTC on 09-10) npm resolved a mixed rc.1/rc.2 peer graph (3062 ERESOLVE lines). The lane now pins an **already-complete** rc.2 (fixes ETARGET) and passes `NODE_OPTIONS=--max-old-space-size=4096` (fixes the OOM). `--legacy-peer-deps` was tried on the way and rejected by real CI: it skips exactly the peers a global install must supply, and `@deepseek-ai/cordis-plugin-group` — required at boot by `dsh-app-boot` — is a peer rather than a dependency, so the CLI died with `ERR_MODULE_NOT_FOUND`.

### v0.19.0

> 📌 **Stable release** (npm `latest`, no prerelease suffix): supports **DSH 0.1.5-rc.1+** only (peer floor `^0.1.5-rc.1`, CI pins `@deepseek-ai/dsh@0.1.5-rc.1`). Hosts on DSH 0.1.5-alpha.2 should stay on **v0.19.0-alpha.1** (the npm `alpha` tag still points there); the 0.1.2-rc.1 stable line keeps using **v0.18.1**.

**✨ New**

- 📝 **The new-tab list gets an optional description back**: DSH 0.1.5-rc.1 restored `SidebarRightGuideEntry.description` (optional), so the plugin restores `TabDescriptor.description` — each of the six built-in types declares a line again (all six guide rows — Files / Changes / Tasks / Side chat / Terminal / Browser — carry one), and the `guideDesc*` keys return to all 20 dictionaries. **The host's native guide renders descriptions only while the listed entries are ≤ 4** (a longer list drops every description rather than truncating), and the plugin contributes six guide entries by default — so in the default composition no description is rendered; they appear once the reader disables enough tab types (per-type switches live on the plugin's settings page) to bring the guide down to four entries or fewer. An entry that declares none stays a single icon + title line (the plugin ships no generic fallback sentence). (#613)

**🐛 Fixes**

- None. The rc.1 delta over alpha.2 is small (373 changed files, overwhelmingly upstream package version bumps, native-sidebar preview UI polish, and test snapshots); apart from the restored description field (plus upstream's `files` type now using its own coloured folder glyph as the guide glyph) nothing needed adapting.

**🧰 CI & internals**

- Baseline moved to **DSH 0.1.5-rc.1+** (#613): peer floor, devDependency pins, the CI mount lane, and `dsh.plugin.json`'s `engines.dsh` all follow (rc.1 is both the `latest` and `next` dist-tag on npm).
- Explicitly unchanged, no need to re-check: the global main-panel model (the `main` slot / `sidebar.panellist` / `ctx.layout` / root-scoped `rightbar` + `rightbar.session`, still not adopted), the file address grammar (`packages/util/workspace-path` only had its version bumped), the native tab-body host contract (`.paneBody` is still a block scroller with a definite height), the core / agent / session / subagent host APIs, and the `ui-primitives` export surface (only CodeBlock rendering changed).
- `@deepseek-ai/dsh-client-ui-primitives@0.1.5-rc.1` still declares no `dependencies` while its bundle still bare-imports `anser` / `shiki` / `@shikijs/langs/*` / `mdast-util-*` / `micromark-*` / `katex` — the third-party devDependencies hoisted in the previous release therefore stay, and must not be reverted.
- Real-host verification (DSH 0.1.5-rc.1 + plugin 0.19.0): `typecheck` / `lint` / `check:consumer-types` green; unit suite **124 files · 1296 passed · 9 skipped**; `pnpm peers check` clean; the mount smoke lane against real rc.1 **7 passed** (including the tab-body fill assertion and the new "descriptions render only at ≤4 guide entries" assertion); on the local 3080 instance the guide still shows six icon+title capsules (6 > 4, so upstream renders no descriptions — upstream also raised the capsule `min-height` from 48px to 56px), clicking `AGENTS.md` in the file tree lands in the plugin editor (CodeMirror mounted), the side-chat composer sits on the pane floor (host box 962px == pane body 962px, composer 8px off the bottom), the bottom workbench's edges coincide with the centre column, and `pageerror` is 0 (the only console noise is the third-party `dsh-tauri-worktree` `/api/dsh-worktree/attach` 500, unrelated to this change).

### v0.19.0-alpha.1

> 🧪 **alpha channel** (npm dist-tag `alpha`, install `dsh-better-sidebar@latest`): supports **DSH 0.1.5-alpha.2+** only (peer floor `^0.1.5-alpha.2`, CI pins `@deepseek-ai/dsh@0.1.5-alpha.2`). Stay on **v0.19.0-alpha.0** for 0.1.5-alpha.1; the 0.1.2-rc.1 stable line keeps using **v0.18.1** (npm `latest`).

**✨ New**

- 🪟 **Every tab body now fills its pane** (#609): the native sidebar's tab-body host is a block scroller with a definite height, not a flex container, and the plugin's tab roots declared only `flex: 1` — so they collapsed to content height and the side-chat composer sat right after the transcript instead of at the pane bottom (a long transcript pushed it out of view). The native adapter now wraps every tab body in a `height: 100%` column flex host, restoring the same fill semantics the bottom workbench has for all plugin tabs, third-party `registerTab` descriptors included.

**🐛 Fixes**

- 🧭 **File address grammar follows DSH 0.1.5-alpha.2**: `fileAddressFor` always produces a session-scoped address and absolute paths keep their leading `/`; `parseFileAddress` is prefix-based and ignores `?`/`#` suffixes.
- 🪟 **Center-column anchor follows alpha.2's global panels**: the `conversation` slot became `main.conversation` under the root-scoped keyed `main` slot, so the locator now resolves the new key and skips `display: contents` slot hosts (alpha.1's old key still works).

**🧰 CI & internals**

- Baseline moved to DSH 0.1.5-alpha.2 (#609): peer floor, 22 devDependency pins, the CI mount lane, and `dsh.plugin.json` engines all follow; `pnpm peers check` is clean (hoisted the `dsh-session-persistence` transitive peer per §3-9).
- **`TabDescriptor.description` removed**: alpha.2's native guide entries no longer render a second line (they are icon + title capsules), so the field and the six `guideDesc*` keys (20 dictionaries) are gone; a new pane's default page is now selected from the registry (exactly one guide entry opens that page directly).

### v0.19.0-alpha.0

> 🧪 **alpha channel** (npm dist-tag `alpha`, install `dsh-better-sidebar@latest`): supports **DSH 0.1.5-alpha.1+** only (peer floor `^0.1.5-alpha.1`, CI pins `@deepseek-ai/dsh@0.1.5-alpha.1`). The 0.1.2-rc.1 stable line keeps using **v0.18.1** (npm `latest`).

**✨ New**

- 🖥️ **DSH's native right sidebar** (#604): the right column is now DSH's own sidebar — all seven plugin tab types register as native tab types with native tab bodies; every file open from the chat goes through `ctx.sidebarRight.openResource(dsh-resource://file/…)`; the `editor` type claims file resources at `extension` priority (outranking the built-in text preview) and takes over the built-in Files page kind (restored on unregister); cross-session opens queue until the target session is on screen.
- 🧩 **Own right panel and free windows retired** (#605): with the right column handed back to DSH, the plugin keeps only its bottom workbench (single split tree, per-session persistence) and registers its toggle into DSH's session-header utilities slot; the float API (`floats` / `floatTab` / `dockFloat` / `raiseFloat` / the "Move to Free Window" menu entry), the `'floatWindows'` feature string, and the `openByDefault` / `defaultWidthPercent` / `changesDiffFloat` settings are gone (a persisted `floats` field is ignored, so old documents still load).
- 🔗 **DSH 0.1.5 host contracts** (#603): the `assistant/chunk` event is gone — live deltas now fold from `agent/assistant-stream` frames (the side chat transcript's `live` field); `sessionPersistence.inspect` is gone — cold reads go through `open(id,'read')`; session headers use `SESSION_FORMAT_VERSION`.

**🐛 Fixes**

- Eight session-event read sites follow the 0.1.5 contracts (side-chat transcript, `jobs.output` replay, fork inheritance); custom seeds now carry the fork marker pair, so they no longer inherit the parent's unclaimed inbox input.

**🧰 CI & internals**

- The real-host mount smoke lane pins 0.1.5-alpha.1 and sweeps the native sidebar's guide page to open every plugin tab type; typecheck / lint / unit tests / mount lane all green.

### v0.18.1

> 📌 **Stable release** (npm `latest`): the DSH baseline is unchanged (**0.1.2-rc.1+**, peer floor `^0.1.2-rc.1`) — this is the incremental cut after v0.18.0: richer op previews in the changes panel, a writable file tree, and five fixes.

**✨ Features**

- 📄 **Op-preview upgrades in the changes panel** (#499): markdown reading mode with mermaid fences, plus inline `.html` and `.pdf` render previews; diff syntax highlighting extended to mjs/cjs/mts/cts, CSS/SCSS/Less, HTML/XML/SVG/Vue, GraphQL, JSONC/JSON5; new **secret redaction** layer (on by default for previews, toggleable in the pane header)
- 🗂️ **File-tree rename / delete** (#550): inline rename plus confirmed delete, slimmer context menus and viewport-clamped submenus
- 🧩 **Plugin catalog names and shell preset text localized** (#535): they now follow the host language

**🐛 Fixes**

- 🔀 **Git diff gap folds really expand** (#576, fixes #577): the fold row promised "n lines… click to expand" but did nothing (`-U3` leaves gap segments without row text); the hidden rows now load on demand through `git.show`, sliced from both sides' contents, with loading / failure states and request deduplication — plus a fix to that route's `rev:path` addressing (it always returned empty before)
- 💬 **Side-chat seeds no longer inherit the parent's unclaimed inbox messages** (#562): the seed carries the fork markers, so the "side chat sends earlier User messages first on long contexts" ghost message is gone
- 🖼️ **Local images in the split markdown renderer** (#569): rewritten to reachable URLs instead of 404ing

**🧰 CI and internals**

- ESLint flat config wired into CI and the Makefile (#536), Makefile command surface (#526), hardened e2e scripts (#527), shared component-test utilities (#524)
- Refactors: Sidebar.tsx split by concern (#542), four polling idioms converged onto `use-polling` (#541), rc.7 `__DSH_MODULES__` fallback removed (#540), One Dark/Light syntax palettes single-sourced (#534), duplicated implementations converged and dead code removed (#525)

### v0.18.0

> 📌 **Stable release** (npm `latest`): this release targets **DSH 0.1.2-rc.1+ only** (peer floor `^0.1.2-rc.1`); 0.1.0-rc.8 ~ 0.1.1-rc.2 are not supported — stable-DSH users should stay pinned to `dsh-better-sidebar@0.17.1`, hosts on 0.1.2-alpha.x keep `dsh-better-sidebar@latest` (v0.18.0-alpha.0).

All changes since v0.17.1 (the two intermediate version numbers v0.18.1-alpha.0 / v0.19.0-alpha.0 were never published; their content is folded into this release):

**🔗 Host track graduation**

- **Onto the DSH 0.1.2 line and graduating to stable**: v0.18.0-alpha.0 dropped the 0.1.1-rc.x compatibility layer and fixed blank Side Chat transcripts on alpha.1+ (#472); the baseline then climbed through alpha.3 (#497) and alpha.5 (#516, `Session.events` → `snapshotEvents()`); the chat file-open funnel moved to `remote.session.openWorkspacePath` (#494) and the "Show in folder" reveal scroll was scoped to the tree body (#453). This release pins the baseline to **DSH 0.1.2-rc.1** (zero source delta vs alpha.5 — a pure version bump; `dsh-client-locale` resumed publishing, everything aligned to rc.1; real-host mount smoke 14/14 in CI)

**✨ Features**

- 🌿 **Unified "Changes" tab** (#475): one tab, two lenses — Git (real diff / history / stage·commit·revert / worktree & child-repo selection) and This Session (live tracking of every file the model reads / writes / edits); a unified diff renderer (mod pairing + intra-line character highlights + syntax coloring + context folding), a draggable bottom preview pane, and one-click expansion into a dedicated diff tab
- 💬 **Side Chat rendering upgrade** (#486): main-conversation-grade Blocks structure, per-turn usage tails, reconnect banner
- ⚙️ **Workspace path fence toggle** (#458): a new `workspaceFence` declarative settings key with a one-click off affordance and guidance on 403 error surfaces

**⚡ Performance**

- 🚀 **Core bundle -45%** (#489): 19 non-zh/en dictionary chunks lazy-loaded, render stabilization (transcript row reuse / tree Sets / batched drags), startup & polling cost cuts (single settings fetch, one git process per tick); a new perf measurement lane; also fixes the bottom-pane drag leaking panel width into the host layout and jumping the native left sidebar
- 📉 Fewer repeated center-column DOM queries (#456)

**🐛 Fixes (selection)**

- ✏️ Editor / Markdown: SSH remote editor links open on the client (#522), reading position kept across preview/edit switches (#467), YAML frontmatter hidden in preview (#394), TOC dismiss-on-outside-click + popover z-index (#461), file basename kept in @-reference links (#417)
- 💻 Terminal / platform: Windows custom shell executables resolve (#503), transient resize failures contained (#428), monospace fallback for unresolvable fonts (#366), Linux absolute paths in WSL workspaces (#455), Windows Explorer reveal selection preserved (#508)
- 🗂️ Layout / state / file tree / chat: desktop shell layout coexists with the side card (#398), no forced mobile drawer on auto-activation (#373), restored free-window id conflicts (#385), tree auto-refresh on window focus (#469), reference affordance pinned to row tail (#509), selection-popup dismissal + caret-anchored draft insert (#427), collapsed toggle cluster aligned (#361), old-engine scroll-jump compat (#448), worktree listing on older Git (#454)

**🧰 CI & internals**

- Windows CI lane (#520), Makefile command surface (#526), e2e script hardening + aggregate double-mount regression (#527), shared component test utils deduplicating boilerplate (#524), duplicate-implementation convergence + dead code removal (#525)

**🌐 Ecosystem**

- 10+ new curated plugins: dsh-better-sidebar-icons (#441), dsh-sidenote (#451, formerly dsh-sidechat #470), dsh-github-workbench (#410), dsh-bilingual-reader (#379), dsh-server-deck (#413), dsh-md-export (#405), dsh-code-nav (#404), dsh-suhuang-scroll (#392), dsh-better-overleaf (#370), and more (each with 18+ language i18n coverage)

### v0.19.0-alpha.0 (0.1.2-alpha.5 adaptation, unpublished, folded into v0.18.0)

> 🧪 **Alpha track**: this release targeted **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.5`, npm dist-tag `alpha`). This number was never published separately — its content shipped in the **v0.18.0** stable release, and the same number was later reused for the 0.1.5 adaptation line (see above).

- 🔗 **Adapted to DSH 0.1.2-alpha.5 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin, the `dsh.plugin.json` engines floor, and the `@deepseek-ai/*` peer / devDependencies baseline moved up to 0.1.2-alpha.5 (verified by a real-host mount smoke 14/14). `dsh-client-locale` has no alpha.5 upstream (newest is 0.1.2-alpha.3), so its peer floor / devDep pin trail the baseline and already accept the alpha.5 runtime (`pnpm peers check` reports zero mismatches — no new transitive peers to hoist). The code adapts to alpha.4's compatibility-flagged change — the `Session.events` property was removed, migrated to the on-demand `snapshotEvents()` API (8 sites: sidechat transcript live reads, fork inheritance, `jobs.output` replay, subagent activity), and the `seedLength` meta field the host dropped was removed from thread creation; alpha.4's remaining changes (bidirectional `send_message`, custom-model discovery reusing Profile headers, `SessionSeq`/`SessionLogOffset` strong typing) and alpha.5's upgrade-startup fix were verified not to touch any other plugin surface.

### v0.18.1-alpha.0

> 🧪 **Alpha track**: this release targets **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.3`, npm dist-tag `alpha`, install `dsh-better-sidebar@latest`). This version number was never published separately; its content is folded into the **v0.18.0** stable release.

- 🔗 **Adapted to DSH 0.1.2-alpha.3 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin, the `dsh.plugin.json` engines floor, and the `@deepseek-ai/*` peer / devDependencies baseline moved up to 0.1.2-alpha.3 (verified by a real-host mount smoke 14/14). All 117 commits between alpha.2 and alpha.3 were audited point by point: every host contract this plugin relies on (token auth, slash RPC, `MarkdownText` labels, the event-stream and persistence APIs behind `sidechat.events`, `SettingsNamespaceInput`, `SUBAGENT_DESCRIPTOR_VERSION` (still 3), `dsh-client-store`, the profile loader, the node-pty pin) is unchanged, so no code adaptation was needed; alpha.3's breaking changes (the required `BeginSubmissionInput.mode`, the renamed `attachment-invalid` subagent error, the removed SQLite persistence backend, the identity-gated projection change feed) were all verified not to touch this plugin.

### v0.18.0-alpha.0

> 🧪 **Alpha track**: this release targets **DSH 0.1.2-alpha.x only** (peer floor `^0.1.2-alpha.2`, npm dist-tag `alpha`, install `dsh-better-sidebar@latest`); 0.1.0-rc.8 ~ 0.1.1-rc.2 are no longer supported — stable-DSH users should stay on v0.17.1 (npm `latest`).

- 🔗 **Adapted to DSH 0.1.2-alpha.2 (published to npm, `alpha` dist-tag)**: the CI mount gate's pin and the `@deepseek-ai/*` devDependencies baseline moved up to it (verified by a real-host mount smoke 14/14). Adaptation points: `dsh-settings` dropped the runtime `settingsNamespace` export (namespaces are now validated at compile time — the host passes the constant directly); the `dsh-subagent` descriptor version went 2→3 (stamped by the host package; the test assertion follows the `SUBAGENT_DESCRIPTOR_VERSION` constant); the restored `SessionEvent.ignorable` and the Remote gateway's unified `RemoteError` wrapping were verified to not affect this plugin.
- 🐛 **Fixed blank Side Chat transcripts on DSH 0.1.2-alpha.1+**: transcript polling still called the `ctx.connection.api` face removed in alpha.1 (the error was silently swallowed, so the tab rendered an empty transcript forever). Transcripts now come from the plugin's own `sidechat.events` route (live threads read the in-memory event log, cold threads read session persistence, with `afterSeq` delta pulls, [sidechat-routes.ts](./src/sidechat-routes.ts)).
- 🧹 **Dropped the pre-alpha (0.1.1-rc.x and older) compatibility layer**: the e2e host RPC collapsed from the dot/slash dual dialect to slash-only (token URL required, [host-protocol.ts](./tests/e2e/host-protocol.ts)); `MarkdownText` labels collapsed to the nested single shape ([markdown-labels.tsx](./src/client/markdown-labels.tsx), no more dual prop names); peerDependencies / devDependencies / `dsh.client.inject` / the chunk externals allowlist all dropped the defunct `@deepseek-ai/dsh-client-runtime` (four synchronized spots).

### v0.17.1

- 🔗 **DSH 0.1.2-alpha.1 adaptation (dual-version compatible)**: fully adapted to DSH 0.1.2-alpha.1's Remote gateway, one-time-token browser authentication, and the `MarkdownText` labels contract change — the plugin works identically on 0.1.0-rc.8 ~ 0.1.1-rc.2 and 0.1.2-alpha.1 (the latter verified by a real-host mount smoke 14/14 against a source build of the GitHub tag; alpha.1 was never published to npm, and the CI pin moved to the npm-published 0.1.2-alpha.2 in v0.18.0-alpha.0). Highlights: all four `MarkdownText` render sites now go through the dual-shape labels helper ([markdown-labels.tsx](./src/client/markdown-labels.tsx)), fixing the `reading 'code'` crash in markdown/mermaid previews on alpha.1; the e2e mount smoke speaks both wire dialects (token-URL cookie exchange, slash `/api` endpoints with parameter-named args, [tests/e2e/host-protocol.ts](./tests/e2e/host-protocol.ts)); dropped the `@deepseek-ai/dsh-client-runtime` peer removed upstream in 0.1.2-alpha.1

- 🧊 **Git panel freeze + restart loop** ([#376](https://github.com/omdsh-dev/DSH-better-sidebar/pull/376), fixes [#369](https://github.com/omdsh-dev/DSH-better-sidebar/issues/369)): opening the Source Control panel could freeze the whole page, and the frozen layout restored itself after every reload with no way out — three unbounded layers compounding, now all bounded: **① status truncation** — the `git status --untracked-files=all` response is capped at 2,000 entries (capped results carry `truncated` and the panel shows a notice, mirroring `fs.read`'s truncation semantics; worktree change counts inherit the bound), so a huge untracked set can no longer freeze the browser main thread; **② bounded repository discovery** — a non-repository cwd (e.g. the home directory) no longer probes every visible child directory serially without limit: probe timeout 30s→5s, at most 200 probed directories, concurrent requests share one in-flight scan plus a 60s TTL cache, ending the `git rev-parse` spawn storm under `~`; **③ reset escape hatch** — loading with `?dsh-sidebar-reset` drops the persisted layout (shared width included) and starts from the default, breaking the loop even when the page is already hung; persisting resumes once the param is gone; `statusTruncated` copy synced across all 19 dictionaries

### v0.16.0

All changes since v0.15.2:

**✨ New features**

- 🪟 **Free windows** ([#354](https://github.com/omdsh-dev/DSH-better-sidebar/pull/354)): drag any tab (built-in or plugin-registered) out of the tab bar **onto the main conversation area** — a dashed drop hint marks the landing zone and release turns it into a floating window (default 390×780, phone-portrait ratio, clamped to the viewport and centered at the drop point). Windows can be moved by dragging the header, resized from the SE corner (≥320×200), raised to the top by clicking anywhere, sent back with the header context menu ("Back to sidebar" / "Close"), and closed with X through the normal `closeTab` lifecycle (pty release etc.). Dragging over a sidebar pane highlights it and releasing **docks** the window back into that pane. `floats` persist per session (restored as-is after refresh, lenient sanitize + geometry clamping). Service semantics: `features` gains `'floatWindows'` — `openTab`'s dedupe/id focus on a floating tab **raises its window** (no duplicate open, no panel expansion), `closeTab` / `activateTab` work on floating tabs and still fire their lifecycle callbacks, `visible` is always true inside a float, and agent-terminal reconcile covers floating windows. Tab content reuses the regular render path; plugin tabs are fully supported. Also ships the 8px-grid spacing cleanup of file sub-pages ([design](docs/plans/2026-08-23-free-window-design.md))
- 📂 **Model-driven sidebar opens (`sidebar_open` tool)** ([#353](https://github.com/omdsh-dev/DSH-better-sidebar/pull/353)): a new global setting `agentOpenTools` (**off by default**) injects **one** tool letting the model open local **files** (editor tab, deduped by path), **folders** (full-window tree rooted there, `meta.dir`) and **HTTP(S) pages** (browser tab, URL prefilled) in the caller's sidebar. Turning the setting off unregisters the tool and clears the undelivered queue; already-open tabs stay. Opens targeting non-active sessions queue and replay when visible (`/sidebar/ws/agent-opens` push, same trust fence). No new public API and no new `/sidebar/api` routes ([design](docs/plans/2026-08-23-agent-open-tools-design.md))
- 📝 **README-level inline HTML + table of contents (TOC) in Markdown previews** ([#360](https://github.com/omdsh-dev/DSH-better-sidebar/pull/360)): previews now genuinely render **block-level inline HTML** — badge walls `<div align=center>`, `<details>` blocks nesting markdown, `<br/>`/`<sub>`/`<img>` inside table cells, `<video>`/`<picture>` — all sanitized through a DOMPurify allowlist (`<script>` and other active content stripped, `<a>` forced `_blank rel=noopener`), with local media `src` rewritten to the session media route. With ≥3 headings a floating **TOC** button appears: smooth scroll, auto-expanding folded `<details>` ancestors, collecting headings from HTML segments too. The renderer is still the host `MarkdownText` (shiki / KaTeX / GFM preserved); pure-markdown documents take the original path with zero regression ([design](docs/plans/2026-08-24-markdown-html-toc-design.md))
- 🌏 **Third-language coverage (19 languages)** ([#339](https://github.com/omdsh-dev/DSH-better-sidebar/pull/339)): optional peer `@huanlin/dsh-plugin-better-locale` adds full dictionaries for ja / de / fr / pt / ko / ar / hi / id / tr / vi / th / ru / it / nl / sv / pl / zh-HK / zh-TW / zh-MO (~340 keys each). Coverage **borrows the DSH English slot**: it is active only while DSH's active locale is `en` and is completely inert under `zh` (no mixed-language UI). The 19 dictionaries are also registered into better-locale so external `ctx.locale.lookup('betterSidebar', key)` callers get the override text. Without better-locale installed `ctx.get('betterLocale')` is undefined and the whole block is a no-op — zh/en behavior is unchanged
- 🌿 **Multi-repository Git selection + linked-worktree discovery** ([#326](https://github.com/omdsh-dev/DSH-better-sidebar/pull/326) [#285](https://github.com/omdsh-dev/DSH-better-sidebar/pull/285)): when the session cwd is a workspace container rather than a Git repository, the Git panel discovers direct child repositories and shows a **repository selector** — status / branch / history / diff / stage / commit / revert / cherry-pick / file opening are all threaded through the selected repository. Linked-worktree change discovery and per-worktree git operations are transactionally bound to the selected checkout (including delayed pagination responses), stale/prunable worktree targets are rejected, and individual inventory failures degrade safely
- 🖥️ **Browser loopback allowlist** ([#365](https://github.com/omdsh-dev/DSH-better-sidebar/pull/365)): a new side-card setting `browserAllowedLoopback` (comma-separated host or host:port entries; bare hosts match every port, host:port matches exactly) lets the sidebar browser navigate to explicitly trusted local addresses. Allowlisted loopback pages additionally get the `allow-same-origin` iframe sandbox token — local dev servers (Vite etc.) need a real origin for their module/HMR/fetch pipeline and would otherwise render blank. The page stays cross-origin to the GUI and to every other site; the server-side `browser.probe` route mirrors the same allowlist
- 📝 **Vue + 28 legacy languages in the editor** ([#202](https://github.com/omdsh-dev/DSH-better-sidebar/pull/202)): `.vue` maps to `@codemirror/lang-vue` (template / script / style dispatch on the `lang` attribute, `<style lang="scss">` preprocessors); zero new dependencies bring scss/sass/less/stylus/ruby/lua/perl/r/dart/scala/groovy/powershell/diff/protobuf/cmake/pug/tcl/haskell/clojure/erlang/julia/pascal/vb/vhdl/stex/objectivecpp via legacy-modes. A throwing language factory degrades to plain text (console.warn) instead of breaking the editor; ambiguous `.v` / `.m` extensions stay unmapped on purpose
- 🔄 **Editor preview refresh trio** ([#215](https://github.com/omdsh-dev/DSH-better-sidebar/pull/215) [#228](https://github.com/omdsh-dev/DSH-better-sidebar/pull/228), fixes [#167](https://github.com/omdsh-dev/DSH-better-sidebar/issues/167)): a **manual refresh** button for text previews; switching back to preview after an edit-save auto-reloads (suppressed while dirty so drafts survive); a successful save while in preview mode reloads on the saved edge. Automatic polling and the `fs.stat` version endpoint are gone (zero background API traffic)
- 🖼️ **Local / relative images in Markdown** ([#292](https://github.com/omdsh-dev/DSH-better-sidebar/pull/292)): `![alt](./img.png)`, `/cwd/img.png` and reference-style `[id]: url` destinations are rewritten to `/sidebar/file` media URLs (still bounded by the session cwd) — previews no longer show just the alt text
- ➕ **New recommended-catalog entry: ego-browser** ([#340](https://github.com/omdsh-dev/DSH-better-sidebar/pull/340)): `@dsh-external/ego-browser` Agent browser tab (registers a sidebar page automatically when better-sidebar is present, falls back to a floating bubble otherwise); description dictionary completed across 19 languages ([#371](https://github.com/omdsh-dev/DSH-better-sidebar/pull/371))

**🐛 Fixes**

- 🛒 **DSH marketplace managed-install compatibility** ([#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)): the public `cordis` entry was removed from `peerDependencies` (the market preview hard-rejects `cordis` in any dependency field — optional does not help), so the npm package satisfies the [dsh-community-market install rules](https://github.com/anywhere-labs/deepseek-harness-desktop/blob/master/dsh-community-market/docs/install-and-uninstall.zh.md) — catalog sources (dshfind / 1024Store) can re-issue the `repository_backlink` verified target and the plugin becomes installable through the Desktop market
- 🔤 **Type base migrated to `@deepseek-ai/cordis`** ([#338](https://github.com/omdsh-dev/DSH-better-sidebar/pull/338)): the declaration surface (`src/context-types.ts`) no longer depends on or restates the public `cordis` — `Context` is now an **intersection** of the real vendored cordis Context with the structural service faces, and the `ctx.betterSidebar` type merge lives on `@deepseek-ai/cordis`. **Consumer migration**: change `import type { Context } from 'cordis'` to `import type { Context } from '@deepseek-ai/cordis'` (the `import type {} from 'dsh-better-sidebar'` merge path is unchanged); plugins that never used that import are unaffected
- 🧩 **All internal `ctx.betterSidebar` reads fixed** ([#357](https://github.com/omdsh-dev/DSH-better-sidebar/pull/357), fixes [#356](https://github.com/omdsh-dev/DSH-better-sidebar/issues/356)): on npm-installed DSH 0.1.1-rc.x (web bundle) the sidebar died on every page load (`cannot get property "betterSidebar" without inject`) — the 26 internal direct reads now go through `ctx.get('betterSidebar')` (root reflect-store resolution, immune to the fiber chain); external consumers keep `inject: ['betterSidebar'] + ctx.betterSidebar`
- 🔐 **Session-workspace boundary for file APIs** ([#345](https://github.com/omdsh-dev/DSH-better-sidebar/pull/345), fixes [#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)): fixed `fs.tree / fs.read / fs.write` workspace escapes; media, HTML preview and uploads share real-path symlink validation; regression tests for absolute paths, symlinks, uploads and nested Git sessions
- 🪟 **Panel-host layering and viewport clipping** ([#330](https://github.com/omdsh-dev/DSH-better-sidebar/pull/330) [#278](https://github.com/omdsh-dev/DSH-better-sidebar/pull/278), fixes [#277](https://github.com/omdsh-dev/DSH-better-sidebar/issues/277)): panel host z-index 40→25 — below the DSH cordis dynamic-plugin layer (30), so the workbench no longer covers cordis inventory/approval surfaces (still above AppFrame's 20 and below the 100+ float stack); `overflow: hidden` on the host clips at the viewport edge, so collapsed panels no longer stretch the document into bidirectional scrolling (measured `scrollWidth` 2289→1672 / `scrollHeight` 1280→1032, any skin)
- 📐 **Layout-push hardening** ([#310](https://github.com/omdsh-dev/DSH-better-sidebar/pull/310) [#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130) [#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)): conversation column gets `min-height: 0` + `overflow: hidden` + `overflow-wrap: anywhere` (long unbreakable URLs / OAuth links no longer push the composer and left-rail Settings out of the viewport); the layout-push effect is split into "set only" + "remove only on unmount" and the width push is gated on `panelOpen` — dragging the bottom height with the right panel closed no longer squeezes the conversation, and release no longer flashes full-width; `useLayoutEffect` removes cross-paint full-width frames; all three drags flush the final frame and sync `centerRect.right` before committing; bottom height caps at `viewportHeight - PANEL_MIN`; drag handles no longer highlight mid-drag
- 📱 **Mobile: unavailable-sidebar clarity + 1px overflow** ([#254](https://github.com/omdsh-dev/DSH-better-sidebar/pull/254)): with no session the toggle uses `aria-disabled` — keeping the non-executable semantics while allowing touch/keyboard focus so the "select a session to use the sidebar" tooltip is reachable; the panel uses `border-box` so mobile `100vw` includes the left border and no longer causes 1px horizontal overflow
- 📏 **Side-card width shared across sessions** ([#36](https://github.com/omdsh-dev/DSH-better-sidebar/pull/36)): panel width is a layout preference, not session content — "last drag wins" writes the global `dsh-sidebar:v1:width` key that fresh and cached session switches adopt; without a global key (first run / pre-existing sessions) behavior is byte-for-byte unchanged
- 🧹 **Terminals close immediately on session delete** ([#130](https://github.com/omdsh-dev/DSH-better-sidebar/pull/130)): new `PtyManager.closeSession()` subscribing to DSH's `session/disposed` — deleted sessions no longer wait for the 30s reconnect grace to release their terminals (agent terminals are agent-lifecycle-owned and untouched)
- 🔍 **Filename search skips noise directories** ([#342](https://github.com/omdsh-dev/DSH-better-sidebar/pull/342)): `node_modules` / `.pnpm-store` / `.yarn` / `.turbo` / `.next` / `dist` / `build` / `coverage` etc. (case-insensitive, `.git` still skipped) — huge dependency trees no longer burn the 100k visit budget and return `truncated` early, so real files in later directories (`docs/`) are found; no `.gitignore` semantics, still filename lookup
- 📝 **Mermaid global error rendering suppressed** ([#341](https://github.com/omdsh-dev/DSH-better-sidebar/pull/341)): `suppressErrorRendering` enabled — invalid diagrams no longer inject a large error SVG into `document.body`; the component-level error fallback and source display remain
- 🖥️ **Terminal Nerd Font icon fallback** ([#190](https://github.com/omdsh-dev/DSH-better-sidebar/pull/190)): supplementary-plane PUA icons in starship / powerlevel10k prompts (Nerd Fonts v3 Material icon set) no longer render as tofu — `withIconFontFallbacks()` appends Nerd Font icon families to the winning base font (before the first generic family, deduped by family name, CSS global keywords filtered, no color-emoji fonts)
- 🌐 **HTML preview declares UTF-8** ([#193](https://github.com/omdsh-dev/DSH-better-sidebar/pull/193), fixes [#170](https://github.com/omdsh-dev/DSH-better-sidebar/issues/170)): `/sidebar/html` responses carry `charset=utf-8` (Chinese fragments without `<meta charset>` no longer mojibake); original file bytes preserved
- 🧪 **trust-fence Origin compared by hostname** ([#182](https://github.com/omdsh-dev/DSH-better-sidebar/pull/182)): some Chromium builds (Edge 151) serialize the Origin of non-default-port loopback pages without the port — `http://127.0.0.1` against `Host: 127.0.0.1:3080` no longer 403s (mirrors DSH's official gateway fence); different hostnames and opaque null origins are still rejected
- 🪟 **"Show in folder" now reveals in the explorer** ([#94](https://github.com/omdsh-dev/DSH-better-sidebar/pull/94)): the folder-reveal gesture no longer opens the directory as a file in the editor (`"..." is a directory`) — `revealInExplorer` switches to the explorer tab, auto-expands a collapsed panel, expands the parent folder and highlights/scrolls to the produced file; the produced-files selector now reads the engine's Turn deliverables (same source as ui-deliverables)
- 🖱️ **Panel-drag layout flash fixed** ([#180](https://github.com/omdsh-dev/DSH-better-sidebar/pull/180)): dragging the bottom height with the right panel closed no longer shifts the conversation left; release no longer flashes full-width before snapping back
- 🖥️ **PowerShell installer fixes** ([#47](https://github.com/omdsh-dev/DSH-better-sidebar/pull/47)): the remote entry is now "download the script → strip the UTF-8 BOM → run it in memory", so `-Version` / `-DryRun` work again under Windows PowerShell 5.1 (the BOM no longer eats the leading `param(...)`); `pnpm --version` is checked before touching the profile (major <10 fails with a clear error and exit code 1)
- 🔄 **Browser embed probing GET fallback** ([#69](https://github.com/omdsh-dev/DSH-better-sidebar/pull/69)): when a HEAD response omits both `Content-Security-Policy` and `X-Frame-Options`, probe retries once with GET — sites like Alibaba Bailian that only advertise their embed policy on GET no longer show a misleading "refused to connect"; they get the friendly "site refuses embedding" panel with an "open in browser" button
- 🔧 **git-source installs fixed via `unrun` devDependency** ([#336](https://github.com/omdsh-dev/DSH-better-sidebar/pull/336)): tsdown 0.22 loads its config through `unrun` and pnpm 11 does not auto-install peer deps — git-hosted `prepare` no longer fails with `Failed to import module "unrun"` (npm tarballs unaffected)
- 🍃 **Strict `ctx.effect` also fixed 4 latent sites**: interception / IME-guard effect bodies returned `undefined` on failure instead of a disposer (invalid shape under the vendored cordis effect contract) — now a no-op disposer

<summary><b>Older releases (v0.12.0 – v0.15.2)</b></summary>

### v0.15.2

All changes since v0.15.1:

**✨ New features**

- 🗂️ **"Open in app" submenu in the file tree** ([#334](https://github.com/omdsh-dev/DSH-better-sidebar/pull/334)): the file-tree context menu gains an "Open in app >" submenu — built-in openers (reveal/select in file manager, VS Code, Cursor, Zed), each with a pin button that promotes it to a top-level context-menu item (click again to unpin); with an optional SSH host configured, VSCode-family entries switch to the `vscode-remote/ssh-remote+<host>/<path>` protocol and local-only entries hide automatically; custom editors supported (name + URL template with `{path}` + "VSCode-family" flag, configured in the Files card gear popup). Open actions go through the new host route `POST /sidebar/api/open.external` (argv-array spawn, no shell injection) ([design](docs/plans/2026-08-22-open-with-menu-design.md))
- 📑 **Tab context menu** ([#331](https://github.com/omdsh-dev/DSH-better-sidebar/pull/331)): right-clicking a tab offers **Close / Close others / Close to the left / Close to the right**, scoped to the current pane (tab group); items grey out when there is nothing to close; the menu only opens — it never switches the active tab; bulk closes go through the existing per-tab `onClose` path so lifecycle callbacks, pty release and agent-terminal shutdown all stay intact
- 📄 **Diff files collapsed by default** ([#270](https://github.com/omdsh-dev/DSH-better-sidebar/pull/270)): each changed-file header is now an accessible expand/collapse control; recognized source files expand by default while tests, docs, generated files, lockfiles and unknown types stay collapsed; the existing 500-row cap for expanded content is preserved
- 📖 **README update**: feature tour converted to a table (two screenshots per row, saves space); community section now shows the WeChat group and QQ group QR codes ([#325](https://github.com/omdsh-dev/DSH-better-sidebar/pull/325), QQ group 577011007)

**🐛 Fixes**

- 🪟 **Prune empty restored panes** ([#268](https://github.com/omdsh-dev/DSH-better-sidebar/pull/268)): persisted split panes left empty when ephemeral diff tabs were dropped no longer survive as full-size blanks — `sanitizeState` now also prunes the empty split leaf and repairs the stale active-pane pointer; a fully empty workbench keeps its single empty pane
- 🖥️ **Hide spawned git windows on Windows** ([#301](https://github.com/omdsh-dev/DSH-better-sidebar/pull/301), fixes [#124](https://github.com/omdsh-dev/DSH-better-sidebar/issues/124)): the shared `runGit()` spawn options now set `windowsHide: true`, so repo-status polling and git actions no longer flash console windows on Windows (no behavior change on other platforms)
- 📁 **Untracked files inside new folders** ([#242](https://github.com/omdsh-dev/DSH-better-sidebar/pull/242)): `git status` switched from `--untracked-files=normal` to `--untracked-files=all` — each file inside a new folder now shows as its own row and its diff can be loaded (no more `fs.read` "is a directory" error), matching VSCode's default behavior
- ⚡ **Per-frame React re-renders eliminated for toggles/drags** (closes [#315](https://github.com/omdsh-dev/DSH-better-sidebar/issues/315)): `centerRect` moved to a ref with direct DOM writes to the bottom bar (zero React renders); `TabContent` memoized with an explicit comparator; a new frame-batcher coalesces Divider/dock drags per frame; meaningless locate passes skipped during drags. 4x CPU-throttled A/B: >17ms frames on toggle collapse 19→6 / expand 24→4~6, p95 21ms→15ms; drags unchanged (non-regression)

### v0.15.1

All changes since v0.15.0:

**✨ New features**

- 💬 **Codex-style transcript rework for Side Chat** ([#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)): transcript rows became **collapsible** — tool calls, thinking and context injections share one quiet single-line chrome (chevron + label + one-line argument summary) that expands into an indented body on a hairline thread, no cards or fills; streaming labels and a creating hero shimmer (shimmer = generating), failed tools go danger, `prefers-reduced-motion` stills every loop; **the first question is no longer swallowed by the boundary prompt** — context injection and first contact are delivered as separate events (boundary + parked snapshot ride `agent.inject`, the question wakes the driver), so the transcript maps injections onto a collapsible injection row while genuine user messages — the first one included — render as user bubbles; legacy threads' first message is split out into its own bubble too
- 📖 **README rewrite**: feature tour (real UI screenshots per feature), user-facing DSH compatibility badges, simplified install (`add` → `approve-builds` → `add`, node-pty-safe build, paste-to-DSH install prompt), 28+ plugin ecosystem with per-category collapsed listings

**🐛 Fixes**

- 🖥️ **Terminal pty stays alive across conversation switches** ([#323](https://github.com/omdsh-dev/DSH-better-sidebar/pull/323)): switching sessions is no longer treated as a transient drop — the client sends a `park` control frame on unmount and the host skips the 30s reconnect-grace countdown; switching back (`open()` cancels parked) or explicitly closing the tab resumes the normal lifecycle; agent terminals keep their indefinite lifetime
- 📂 **File-tree upload overlay no longer intercepts Tab drags** ([#317](https://github.com/omdsh-dev/DSH-better-sidebar/pull/317)): dragging tabs (reorder / cross-pane split) across the explorer no longer shows the upload overlay or swallows the event — gated on `dataTransfer.types` containing `Files` (consistent with the panel-host shield), so tabs land normally; OS file drags behave as before
- 💬 **Subagent auto-open debounced** ([#314](https://github.com/omdsh-dev/DSH-better-sidebar/pull/314)): Side Chat thread creation no longer pops the task page — the 0→N trigger rearms for 500ms and re-evaluates the original baseline against the live snapshot, by which time the title filter recognizes the thread; genuine subagents still auto-activate the Tasks page (wide viewports expand the sidebar, while narrow viewports prepare the tab without forcing the drawer open)

### v0.15.0

All changes since v0.14.0:

**✨ New features**

- 💬 **Side Chat (beta) tab** ([#286](https://github.com/omdsh-dev/DSH-better-sidebar/pull/286)): Codex-style side threads, **one independent tab per conversation** — the child inherits the parent's full context (completed turns + pending messages + the in-progress turn's assistant output and tool activity, honestly frozen with an "interrupted" marker); created with an identical composition (same preset / provider / model) so the first request reuses the parent's input prefix cache; threads stay invisible in the main session list with zero subagent-catalog noise; follow-ups survive DSH restarts (auto cold-resume); one-click "Save as new session" promotes the thread to a top-level session ([design](docs/plans/2026-08-20-sidechat-tab-design.md))
- 📤 **Upload into the files window** ([#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)): header "upload file / upload folder" buttons plus drag-drop (drop on the tree body = workspace root, on a directory row = that directory, on a file row = its parent directory, VSCode semantics); full-window blurred progress overlay while uploading (per-file progress + cancel / Esc); buttons disabled while busy, tree refreshes after the upload settles
- 🧩 **Desktop compatibility in four options** ([#284](https://github.com/omdsh-dev/DSH-better-sidebar/pull/284)): "Position compatibility mode" is now a main-row dropdown — **Auto-detect** (default, conservative: only the standard Window Controls Overlay geometry contributes; real 32/36px caption-overlay heights per shell, live on maximize/restore; zero modification on plain web) / **DSH official web** (explicitly no adaptation) / **Shell preset** (built-in, opt-in; only shells that appeared in this repo's issues/PRs with 100+ stars, "detected" badge when the environment matches) / **Custom** (free-form CSS + shift distance). Documents that already carried compatibility values migrate to the custom scheme; interactive chrome opts out of desktop drag regions (`no-drag`); the bottom-push anchor is a composite selector (`[data-pane]` and `:has(> [data-slot])`)
- 🎛️ **Settings page UI/UX modernization** ([#300](https://github.com/omdsh-dev/DSH-better-sidebar/pull/300)): the side-card secondary-settings entry is now a full-width "Feature settings" strip at the card bottom (replacing the invisible corner gear — much easier to discover); coordinated two-tone enabled state (brand activation accent + success-green check badge); every color is still `--dsw-alias-*` token-derived so skins follow automatically
- ➕ **New entries in the recommended-plugin catalog**: `dsh-docs-panel` (global docs, [#230](https://github.com/omdsh-dev/DSH-better-sidebar/pull/230)), `dsh-flowglass` ([#261](https://github.com/omdsh-dev/DSH-better-sidebar/pull/261)), `dsh-git-forge` and `dsh-ssh-tunnel` ([#204](https://github.com/omdsh-dev/DSH-better-sidebar/pull/204)), `dsh-turn-review` ([#102](https://github.com/omdsh-dev/DSH-better-sidebar/pull/102))

**🐛 Fixes**

- ⚡ **Batched live preview for the subagent page** ([#298](https://github.com/omdsh-dev/DSH-better-sidebar/pull/298)): the old implementation polled `subagents.history` per running subagent, each poll triggering a full host-side enumeration — an O(N²) amplification that stalled the page with many concurrent subagents; now a single batch route `subagents.live` (one enumeration of the whole tree) plus one client poller with a single in-flight request; display logic and copy unchanged
- 🖱️ **Interrupted / fast-release drags no longer roll back** ([#249](https://github.com/omdsh-dev/DSH-better-sidebar/pull/249), closes [#247](https://github.com/omdsh-dev/DSH-better-sidebar/issues/247) [#248](https://github.com/omdsh-dev/DSH-better-sidebar/issues/248)): interrupted or fast-released drags commit the last known position; HMR re-activation re-locates the center column (fixes the blank bottom panel after a hot reload)
- 📐 **Push variables stay effective while mounted** ([#259](https://github.com/omdsh-dev/DSH-better-sidebar/pull/259), fixes [#258](https://github.com/omdsh-dev/DSH-better-sidebar/issues/258)): the bottom panel no longer flashes full-width after a drag is released
- 🔐 **Workspace boundary hardening for file APIs** ([#328](https://github.com/omdsh-dev/DSH-better-sidebar/issues/328)): `fs.tree/read/write`, media, HTML preview, and uploads now share real-path containment checks that reject outside absolute paths and symlink escapes
- 🔧 **Adapted to DSH 0.1.1-rc.1 / rc.2 (@next)** ([#297](https://github.com/omdsh-dev/DSH-better-sidebar/pull/297) [#305](https://github.com/omdsh-dev/DSH-better-sidebar/pull/305)): no code changes needed
- 🔒 **Upload-chain hardening** ([#239](https://github.com/omdsh-dev/DSH-better-sidebar/pull/239)): empty and absolute `relativePath` segments are refused outright; uniquely named temp files (concurrent uploads stay independent, crashed processes never block later uploads); write-stream error listeners (a failing disk can no longer crash the host); client error codes unified with the wire (`too-large`), 413s localized

### v0.14.0

> ⚠️ This release requires DSH ≥ 0.1.0-rc.8. All changes since v0.13.1:

**✨ New features**

- 🖼️ **Unified panel-host injection refactor** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): panels/toggle clusters moved into a `[data-dsh-panel-host]` fixed containing block (`fixed inset-0 z-40`), immune to desktop-shell intermediate transforms hijacking `fixed`; mount self-check (page-level transform → `data-dsh-panel-host-degraded` degraded sync, judged on uncorrected geometry, exits only when the ancestor transform is gone); push anchor switched to `#root [data-dsh-frame] > [data-pane="conversation"]` + `#root` calc width against desktop-shell additive overflow; chunk revalidation on activation (HEAD+ETag keeps unchanged chunks, 5s timeout fails open); `visualViewport` keyboard inset + `env(safe-area-inset-*)` mobile adaptation
- 📂 **Separate file windows by default** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): `editorExplorer` now defaults to **separate** — tree clicks / file opens create a new tab per path and the path-less window is a pure file manager; merged mode stays available as an opt-in
- 🖥️ **Terminal shell / shellArgs configurable from the settings page** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): the terminal card's gear popup gains "Shell path" and "Shell arguments" rows (previously yaml-only via `cordis.patch.yml`) — saved values take effect immediately for terminals opened afterwards (UI terminals and model `terminal_create` alike); empty keeps the existing yaml → `$SHELL` / login shell / `powershell.exe` resolution order
- 🏷️ **Version badge on the settings page** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): the side-card settings section now opens with a `DSH-better-sidebar v0.14.0` identity badge (version synced with the service instance, test-guarded)
- 🔍 **Add-plugin catalog: search / grouping / independent scroll** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): built for a growing plugin ecosystem — a live search box (filters by name / id / description), optional `category` grouping for entries, and an independently scrolling list (the modal no longer grows unbounded with catalog size)

**🐛 Fixes**

- 🧩 **rc.8 module-system migration** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): rc.8 no longer exposes the `window.__DSH_MODULES__` page global (it moved to the `ctx.modules` service), which broke every lazy chunk's externals resolution — the client now injects the `modules` service and shares it with chunk-bundle copies through a plugin-owned global (terminal / editor / Mermaid on-demand loading restored)
- 🧩 **Chunk revalidation barrier hardening** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): HEAD revalidation gains a 5s timeout (fails open on a stuck route so the barrier can never wedge lazy loads); `resetChunks` clears a pending revalidation barrier
- 🖱️ **Drag robustness** ([#232](https://github.com/omdsh-dev/DSH-better-sidebar/pull/232)): fast releases (browsers merge/lose pointermove bursts) commit the last known dragged position instead of rolling back; `pointercancel` / lost-capture interruptions keep the drag result too; the center column is re-measured right after commit (no mid-frame bottom-panel width jump); HMR re-activation re-locates the center column via an `<html>` style observer plus a retry when the bottom panel opens (fixes the blank bottom panel / shifted input bar after a hot reload)

### v0.13.1

**✨ New features**

- 📊 **Safe Mermaid rendering in the Markdown preview** ([#164](https://github.com/omdsh-dev/DSH-better-sidebar/pull/164)): when a previewed md file contains mermaid fences, a `client-mermaid.js` chunk (~7MB) is served on demand (zero load without mermaid); defense-in-depth rendering — `securityLevel: 'strict'` + `htmlLabels: false` (node labels use real SVG `<text>`) + a second sanitize pass before SVG injection (foreignObject/script/foreign HTML elements removed, `@*`/`on*`/`href` attributes stripped); click a diagram to zoom in a modal overlay (wheel zoom centered on the cursor, drag pan, toolbar & shortcuts), re-renders with light/dark theme, falls back to the raw code block on parse failure
- 🖥️ **Configurable terminal shell & shellArgs** ([#125](https://github.com/omdsh-dev/DSH-better-sidebar/pull/125)): `cordis.patch.yml` `better-sidebar.config` can set `shell` / `shellArgs` (a non-empty `shellArgs` fully replaces the defaults; unset keeps the previous auto-resolution of `$SHELL` / login shell / `powershell.exe`), applied to both UI terminals and agent terminals (`terminal_create`); terminal tab titles now show the shell name (bash/zsh/powershell) and internal tab ids use UUIDs so the same shell can open multiple terminals

**🐛 Fixes**

- 🔗 **Aggregate double-mount auto-yield** ([#200](https://github.com/omdsh-dev/DSH-better-sidebar/pull/200)): when an aggregate package (e.g. dsh-web-ui-all) mounts the same package under its own entry id, the guard expression in `cordis.patch.yml` disables the plugin's own `better-sidebar` row so `/sidebar/api` is no longer registered twice (`duplicate prefix route` crashing the whole plugin tree / `dsh web`); standalone installs behave as before
- 🔧 **Adapted to DSH 0.1.0-rc.7** ([#207](https://github.com/omdsh-dev/DSH-better-sidebar/pull/207), fixes [#206](https://github.com/omdsh-dev/DSH-better-sidebar/issues/206)): fixes the `agent-presets: refusing to compose an unscoped context` error when picking a model / sending a message after DSH moved to rc.7

### v0.13.0

**✨ New features**

- 📁 **Files window merged with the explorer** ([#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)): new `editorExplorer` setting (editor card gear) — file tabs gain a path-input header plus a toggleable right-docked file tree (per-tab open/width memory, drag-resize 160–480px from the left edge, global filename search via the host `fs.search` route with a hard budget, skipping `.git` and symlink dirs); in separate mode (default) tree clicks / Enter in the path input open each file **in its own new tab**, merged mode switches the current tab **in place**; fresh sessions seed an empty Files window instead of the explorer tab, and a path-less window is a bare file manager in separate mode / a chrome'd empty file window in merged mode; the tree context menu offers "Open in new tab" and "Open to the side" (split)
- 🎛️ **Select rows for declarative settings** ([#151](https://github.com/omdsh-dev/DSH-better-sidebar/pull/151)): settings rows gain `type: 'select'` (`options` with value/title/desc/icon, `multi` stores the picked values as an array); options with icons render big-icon option cards and keep the icon in the closed anchor; `editorExplorer` became an iconed select (merged vs separate); the capability list gained `settingSelect`
- 🔀 **Mutual exclusion with the dsh-web-ui family right panel** ([#181](https://github.com/omdsh-dev/DSH-better-sidebar/pull/181)): reads the `aionui-panel` settings namespace's provider choice — when "Use aionui-panel" is selected, the whole better-sidebar (right sidebar / bottom panel / floating entry / all takeovers) does not mount; with DSH-better-sidebar (or no aionui installed) it behaves as before. Takes effect live after a settings save (settings-document push), no reload needed

### v0.12.3

**✨ New features**

- 🎨 **Skin compatibility (token-driven)**: fully consumes DSH design tokens and follows the dsh-web-ui skin center's 10 skins automatically; terminal/editor surfaces fall back to opaque backgrounds under transparent/translucent-glass token values so text never scrolls over the skin art ([#110](https://github.com/omdsh-dev/DSH-better-sidebar/pull/110), fixes #106 #105 #90 #60, also #52 #57 #92)
- 🗂️ **Unified path handling**: UNC / symlink classification (directory symlinks expandable, broken links highlighted) + HTML-route platform guards ([#134](https://github.com/omdsh-dev/DSH-better-sidebar/pull/134), #65 #67 #43 #79 #115)
- 🖥️ **Configurable terminal shell**: custom shell setting with Windows pwsh auto-probe ([#95](https://github.com/omdsh-dev/DSH-better-sidebar/pull/95))
- 📝 **Editor languages**: C# / Kotlin / Swift syntax highlighting ([#120](https://github.com/omdsh-dev/DSH-better-sidebar/pull/120))
- 🧭 **Settings nav icon**: settings-page navigation icon and layout polish ([#114](https://github.com/omdsh-dev/DSH-better-sidebar/pull/114))
- ➕ **Recommended-plugin catalog**: added `dsh-git-remotes` — Git Remotes tab (branches/upstream/ahead-behind, fetch with prune, ff-only pull, confirm-before-push; does not replace the built-in stage/commit tab) ([#91](https://github.com/omdsh-dev/DSH-better-sidebar/pull/91)); and `dsh-video-preview` — inline video preview (.mp4/.webm/.mov/.mkv/.avi etc.) backed by a /video host route with HTTP Range (206) scrubbing, not capped by the 20MB mediaLimit ([#126](https://github.com/omdsh-dev/DSH-better-sidebar/pull/126))

**🐛 Fixes**

- 🔧 **xterm migration**: deprecated xterm dependency migrated to `@xterm/xterm` (Closes [#122](https://github.com/omdsh-dev/DSH-better-sidebar/issues/122), [#128](https://github.com/omdsh-dev/DSH-better-sidebar/pull/128))
- 📝 **Markdown editor**: selection-to-conversation popup restored ([#24](https://github.com/omdsh-dev/DSH-better-sidebar/pull/24))
- 🖼️ **Markdown preview renders local/relative images**: image destinations that point at local files (relative/absolute paths, reference-style `[id]: url`) are rewritten to `/sidebar/file` media URLs and displayed in the preview (previously only absolute http(s) images rendered; relative paths showed just the alt text)
- 🐛 **node-pty load failure no longer crashes the server** ([#140](https://github.com/omdsh-dev/DSH-better-sidebar/issues/140)): the host half now lazy-loads node-pty — when it is missing the plugin still mounts, the terminal shows a repair banner (copyable command + Retry button), and agent terminal tools are skipped
- 🧪 Test engineering: unit spec split (#141) + flaky smoke cleanup fix
