 # Changelog

-## 0.16.0-beta.1 - 2026-11-10
+## 0.16.0-beta.2 - 2026-11-11

 - **Background tasks:** Paseo now shows the background tasks an agent is running, such as shells and monitors, above the composer, with a Stop button for each. Works with Claude Code, Codex and OpenCode v2. ([#6220](https://github.com/getpaseo/paseo/pull/6220), [#9162](https://github.com/getpaseo/paseo/pull/9162) by [@fxlelouarn](https://github.com/fxlelouarn))
- **Faster diff loading:** Opening Changes shows the file tree right away while file contents load. Large diffs arrive in batches, so the rest of the app keeps responding while they load, and diffs take priority over the daemon's background worktree scans. ([#8907](https://github.com/getpaseo/paseo/pull/8907), [#9241](https://github.com/getpaseo/paseo/pull/9241), [#9243](https://github.com/getpaseo/paseo/pull/9243))
- **Fewer reconnects on return:** Returning to the app keeps a working connection, including one in the middle of a large response, and reconnects once when it has to. On a host with several saved connections, Paseo stays on the one that works. ([#8651](https://github.com/getpaseo/paseo/pull/8651), [#9086](https://github.com/getpaseo/paseo/pull/9086), [#8855](https://github.com/getpaseo/paseo/pull/8855), [#9116](https://github.com/getpaseo/paseo/pull/9116))
- **Keyboard shortcuts on mobile:** With a keyboard connected, iPad and Android now run the same shortcuts as desktop, including your custom bindings. Shortcut hints and Settings → Shortcuts appear when a keyboard is detected. Shortcuts also work in narrow desktop and browser windows. ([#8625](https://github.com/getpaseo/paseo/pull/8625) by [@jeroenfrenken](https://github.com/jeroenfrenken), [@lstroud](https://github.com/lstroud))
- **Touch-sized tablet controls:** On iPad and other touch-screen devices, the wide layout now has touch-sized buttons, rows and bars. The composer toolbar folds its controls into the model menu when space runs out, and swiping right on the workspace reveals a collapsed sidebar as an overlay. ([#8748](https://github.com/getpaseo/paseo/pull/8748), [#8885](https://github.com/getpaseo/paseo/pull/8885), [#8891](https://github.com/getpaseo/paseo/pull/8891), [#8909](https://github.com/getpaseo/paseo/pull/8909), [#9151](https://github.com/getpaseo/paseo/pull/9151), [#9238](https://github.com/getpaseo/paseo/pull/9238), [#8739](https://github.com/getpaseo/paseo/pull/8739) by [@zeyugao](https://github.com/zeyugao))
 - **Plugin sidebar views:** A plugin can replace the sidebar's content with its own layout of workspaces, agents, projects and terminals across every connected host. Pick the view per device under Settings → Sidebar; Paseo's sidebar header and footer stay in place. ([#8906](https://github.com/getpaseo/paseo/pull/8906))
 - **Plugin composer controls:** Plugins can add their own controls to the composer, and read and set its prompt, attachments, provider, model, mode and thinking. They can also put the cursor in any agent's composer, add items to New workspace, and store their own metadata on agents and workspaces. ([#8744](https://github.com/getpaseo/paseo/pull/8744), [#9209](https://github.com/getpaseo/paseo/pull/9209), [#9207](https://github.com/getpaseo/paseo/pull/9207))
+- **Faster diff loading:** Opening Changes shows the file tree right away while file contents load. Large diffs arrive in batches, so the rest of the app keeps responding while they load, and diffs take priority over the daemon's background worktree scans. ([#8907](https://github.com/getpaseo/paseo/pull/8907), [#9241](https://github.com/getpaseo/paseo/pull/9241), [#9243](https://github.com/getpaseo/paseo/pull/9243))
 - **Polish:** The chat stays still when a turn ends, and returning to a chat that has not changed shows it as it is with no refresh. Tool rows show their final title and icon from the first frame, the context window popover opens with usage already loaded, and sidebar hover cards open one at a time. ([#8944](https://github.com/getpaseo/paseo/pull/8944), [#9175](https://github.com/getpaseo/paseo/pull/9175), [#9242](https://github.com/getpaseo/paseo/pull/9242), [#9248](https://github.com/getpaseo/paseo/pull/9248), [#9212](https://github.com/getpaseo/paseo/pull/9212), [#9071](https://github.com/getpaseo/paseo/pull/9071))
 - **Rebuilt mobile chat timeline:** The chat timeline on iOS and Android was rebuilt. Expanding or collapsing a turn summary, todo card or tool-call group keeps the line you tapped in place, and on Android so do Show more, Show less and plan cards. ([#8717](https://github.com/getpaseo/paseo/pull/8717), [#9085](https://github.com/getpaseo/paseo/pull/9085))
+- **Keyboard shortcuts on mobile:** With a keyboard connected, iPad and Android now run the same shortcuts as desktop, including your custom bindings.

 - **Undo workspace archive:** Archiving a workspace in the app now shows a "Workspace archived" toast for six seconds. Undo, or Cmd/Ctrl+Z, restores the workspace with its tabs and agents. On desktop, sidebar workspace rows also get an archive button on hover. ([#8904](https://github.com/getpaseo/paseo/pull/8904), [#9104](https://github.com/getpaseo/paseo/pull/9104))
+- **Fewer reconnects on return:** Returning to the app keeps a working connection, including one in the middle of a large response, and reconnects once when it has to.

 - **后台任务**：Paseo 现在会在 Composer 上方显示 Agent 正在运行的后台任务，例如 shell 和监视器，每项都带“停止”按钮。支持 Claude Code、Codex 和 OpenCode v2。 ([#6220](https://github.com/getpaseo/paseo/pull/6220), [#9162](https://github.com/getpaseo/paseo/pull/9162)，贡献者：[@fxlelouarn](https://github.com/fxlelouarn))
- **更快的 diff 加载**：打开“更改”时会立即显示文件树，文件内容随后加载。大型 diff 分批到达，加载期间应用的其他部分照常响应，并且 diff 优先于 daemon 的后台 worktree 扫描。 ([#8907](https://github.com/getpaseo/paseo/pull/8907), [#9241](https://github.com/getpaseo/paseo/pull/9241), [#9243](https://github.com/getpaseo/paseo/pull/9243))

+# Pi resumed subagents — #9200
+
+## Scope and provenance
+
+An AI agent ran this QA through Playwright/CDP attached to the **real macOS Electron renderer**, using an isolated desktop-managed daemon. The user authorized the run; this is not a claim that the user personally operated the UI. No production daemon, installed package, or daily host configuration was changed.
+
+Desktop evidence was captured on the modified **0.15.3 development checkout** at base `e260f93cc7b6098f6b175bd0e5c7eb24d3f03cf4`, with Electron 44.2.0, Pi 1.5.0, and installed pi-subagents 0.86.0. The final branch was subsequently fast-forwarded to `d46ee6558c043f9fb377d20f05ff662ce27a31f6` (0.15.4). The adapter and test file stayed byte-for-byte identical. The lockfile changes only workspace version references; third-party dependency entries did not change. Server declarations were rebuilt and the checks below passed on the final base. **These screenshots are not a 0.15.4 release-package test.**
+
+## Before and automated checks
+
+Issue #9200 reports ordinary async spawn appearing in the track while successive successful resumes disappear. The original adapter rejects any `action` and requires top-level `agent`/`task`, which a resume does not supply. A separate file-only transcript deduplication also prevents a new attempt row from following Pi's reused session file.
+
+[Captured command output](validation.txt) contains:
+
+- RED on the original adapter: a successful resume returns no descriptor instead of a running row.
+- RED on the intermediate implementation with old file-only deduplication: the next resumed row gets no transcript.
+- Final **21/21** tests passing, including consecutive resumes with a real shared temporary JSONL, polling, notice/replay routing, late old-notice isolation, `bg_wait`, failed/management calls, missing launch identity, and the task alias. Existing spawn fixtures still pass.
+- Full `npm run format`, `npm run typecheck`, `npm run lint`, and `git diff --check` passing after the base update.
+
+Only the specific adapter test file was run, not the full suite. CI has not been run. There is no old-desktop before screenshot; the reported failure and the two actual RED runs are the before evidence.
+
+## Real desktop steps and observations
+
+1. Built server/app dependencies and launched the existing desktop dev runner with a separate home, Electron userData, Pi configuration/session directory, and async root. The final endpoints were loopback-only: daemon 6768, Metro 8082, and CDP 9223. The renderer's desktop bridge confirmed its own managed daemon/home/server identity. Only the existing pi-subagents extension and a marker-only test agent were enabled; child tasks used `sleep`/`printf`, not workspace edits.
+2. Created a Pi parent through the normal Paseo **CLI/API**, asking it to call `subagent({agent:"qa-marker", task, async:true})`. This produced A. The model first enabled the subagent tool, then performed the ordinary spawn. This step was not submitted through the composer.
+3. Used the real Electron **composer** to ask Pi for `subagent({action:"resume", id:A, message})`, then resumed B the same way to produce C. No top-level `agent`, `task`, or `async` was supplied to these resume calls. All three finished with their requested markers.
+4. Opened the provider-owned track while C ran: it showed `1 working`, the follow-up description, and `qa-marker`. Opening that row showed the reused child conversation and the current Shell call. Each resume had a new run/async directory, while all attempts reused the same session JSONL.
+5. While C was still running, clicked **Archive finished subagents**. Completed A/B rows disappeared, while C remained visible as `1 working`.
+6. Submitted a nonexistent resume ID through the composer. Pi returned an error and the parent reported “not found”; no new row or async run appeared.
+7. The first B screenshot was taken after B finished because screenshot capture waited for fonts. It is not offered as running-state proof. A supplementary real resume from A, B_OBSERVE, was captured as `1 working` and opened successfully. It also finished. The final track contained exactly the four successful runs, not a fifth phantom from the failed resume.
+
+The [selected real tool arguments/results, final statuses, and four completion notices](desktop-observations.json) preserve the test UUIDs. B's `revivedFrom` is A; C's is B. This file contains selected fields from persisted Pi entries/status files, not synthesized launch details. The [dialogue DOM excerpt](dialogue-excerpt.txt) records opening a resumed child. Test-root paths are replaced with `<QA_ROOT>` and the encoded workspace directory with `<QA_WORKSPACE>`; no auth or models configuration is included.
+

+
+Each resumed attempt intentionally gets its own row and reads the whole reused child transcript, including earlier history; it does not slice history by attempt. Old-notice isolation is also covered by the automated regression and the earlier real-notice host replay, rather than forcing a delayed notification in the desktop run.
+
+Short-lived duplicate Shell text was observed in the streaming child pane; its cause was not established and it is not claimed fixed here. The earlier direct-SDK smoke's turn-end persistence error did not recur through this normal RPC run. All four test runners exited, the parent settled idle, and the temporary workspace stayed empty. No claims are made about old workflow issues or daemon-restart global adoption.

 ## Changelog ordering

-Highlights come first, ordered by user impact. Entries within each section (Added, Improved, Fixed) follow the same order:
+Rank highlights by how much of a user's day the change touches: how many users get it, and how
+often they meet it. Put every highlight in one of four groups, then order each group by the same
+question.
+
+1. **New capabilities.** Something a user could not see or do in the last release:
+   `Background tasks`, `Plugin sidebar views`.
+2. **Everyday things that got better.** Speed, steadiness and polish in what users already do
+   every session: `Faster diff loading`, `Polish`.
+3. **Changes for part of the audience.** They need a particular device, provider or setup:
+   `Keyboard shortcuts on mobile`, `Touch-sized tablet controls`.
+4. **Small conveniences and highlighted fixes.** A user is glad to find them and would not update
+   for them: `Undo workspace archive`, `Fewer reconnects on return`. Fixes are routine, so one
+   that earned a highlight still follows everything new or improved.
+
+- **Reach decides before kind.** A new capability that needs a hardware keyboard is in group 3.

-History is append-only: rewind, import, reload and archive never delete or rewrite a row. Only

-
- **Rewind** retires a range of rows. They leave the conversation and stay stored, in the same

-  attachments, changes nothing and is reported as diverged. A provider child Paseo already holds,
-  listed or retired, is never imported again.
- **Archive and reload** keep the history and the provider children. An archived chat reads them

-`epoch` is the stored history's identity, minted once when the history is created.
-
-`AgentTimeline` serializes every operation of one agent, child scopes included, and keeps its
-state in an `AgentTimelineBackend`: the sequence, the rows and retirements, prompt identities, the
-open rewind, and the children. The backend contract suite is `agent-timeline.test.ts`, run over
-`TIMELINE_CONTRACT_BACKENDS` in `timeline/testing.ts`. The only backend keeps everything in
-memory, so a daemon restart loses the owned history: the next resume imports provider history into
-a new epoch, and clients take the destructive reset below. Rewinds retired before the restart come
-back if the provider history still holds them. Retained history costs memory for every loaded,
-closed or archived agent until the daemon exits or the agent is deleted.

-An open rewind is stored with the history. Resuming an agent whose history holds one settles it

Mohamed Boudra	a886bfbcdd	Give plugins an agent's background work count and a background flag on hooks (#9362 ) * feat(plugins): give plugins the agent's sidebar indicator and background flag Plugin UI re-derived agent state from status and attention fields and could not see background work, so it showed agents as done while a shell they left running was still live. Agent snapshots now carry the sidebar's own bucket as indicator/indicatorLabel, computed by the same function the sidebar uses so the two cannot drift. Lifecycle hooks and the agent.open.before request now carry `background`, so a hook can skip a hidden helper agent without a lookup. A hook cannot change it; an omitted value means unchanged, like metadata. `finished` attention still means the turn finished; background work is the indicator's concern. * fix(plugins): keep session-open hooks that omit background typechecking A hook that returns its own object instead of spreading the request has no background field; the result type now treats it as optional, like metadata, matching the runtime where an omitted value means unchanged. * refactor(plugins): give agent snapshots the background work count instead of an indicator * fix(plugins): keep legacy session-open hooks that omit background typechecking	2026-11-11 15:10:13 +07:00

Brandon Elliott Brandon Elliott Claude Opus 5.5	ee6a2bba77	fix(server): report and remove a plugin the runtime terminated (#9285 ) When a plugin sent an invalid IPC message, the runtime terminated it by disconnecting the IPC channel and then killing the process. Node never emits "close" for a child whose channel the parent disconnected, and "close" is where the runtime handles an exited plugin, so the process died but the plugin stayed in the catalog, its session stayed open, nothing reported the exit, and calls to it failed with "does not contribute RPC" instead of "Plugin is not available". terminatePluginChild() now only kills the process; the channel closes with it, and "close" fires as for any other exit.

Mohamed Boudra	6e5742fbc6	Rename sidebar workspaces in place on wide web layouts (#9280 ) * feat(app): rename sidebar workspaces in place on wide web layouts At lg and up on web, Rename from a sidebar row's kebab or context menu turns the title into an input instead of opening the modal. The input fills a box exactly one title line tall and its focus outline paints outside that box, so the row never moves. Enter or blur saves, Escape discards. Narrower and native layouts keep the modal; the native-wide device flows drive it. The field stays on screen, read-only, holding the submitted title until the renamed workspace arrives. The daemon answers workspace.title.set before it pushes the workspace update, and queues that update behind any in-flight ones for the workspace, so closing on the answer would show the old title. While editing, the row detaches its press, drag and context-menu handlers rather than becoming disabled: a disabled row sets aria-disabled, which makes the input inside it read as disabled. A ContextMenuTrigger with its menu off now leaves the browser's own menu alone, so copy and paste work in the field. The rename modal moves into the new workspace-rename module, and the unused sidebar-workspace-row.tsx is removed. * fix(app): keep a title renamed elsewhere when an untouched inline rename closes The unchanged check compared the field's text against the workspace's live title, while the field keeps the text it opened with. A rename from another client during an untouched edit made closing the field send the old title back. The inline session now owns its starting text for both the field and the unchanged check. * fix(app): hold a saved inline title against the title it replaced The field closed once the row's title moved off the one editing started from. When another client renamed the workspace while the field was open, that title had already moved, so a save closed the field on the daemon's answer and showed the other client's title until the saved one arrived. The session now records the title at submit and waits for it to change. * fix(app): close an inline rename that submits the row's current title Saving the title another client had just set left the row's title where it was, so the saved phase waited forever with the field read-only and the row's press and menu handlers off. A submit matching the current title now closes without a request. * fix(app): finish an inline rename when the row shows the accepted title The saved phase treated any title change as confirmation of this save. A rename from another client delivered before ours closed the field early and showed that title, and saving a title the row already had never changed it, leaving the field read-only and the row's handlers off. The daemon's response carries the accepted title; the field now closes once the row shows it. That rule also covers a submit matching the current title, so the special-case comparison for it is gone. * fix(app): close an inline rename that a later rename supersedes The daemon builds each workspace update from its latest record, so a rename committed after ours was accepted can be published in its place and ours never appears. Waiting for the accepted title then left the field read-only and the row's handlers off. The saved phase now ends on the first title change the row renders after the answer, or on the accepted title if it is already showing. The session tracks the row's title while saving so a rename delivered before the answer does not count.	2026-11-11 10:36:27 +07:00
Mohamed Boudra	97d39a0158	docs(release): say how changelog highlights are ranked The highlight order of 0.16.0-beta.1 was wrong twice: first in the order the pull requests were collected, then with the maintainer's four named items on top in the order they were typed, which pushed Background tasks to fifth. The doc only said "biggest first", so there was no test to apply. Changelog ordering now owns the ranking: reach and frequency, four groups, and what to do with a maintainer correction. The entry puts Background tasks back at the top; no wording changes.	2026-11-11 03:03:46 +01:00

Mohamed Boudra	603ee5ced1	fix(app): paint a long user message collapsed from its first frame (#9302 ) MessagePreview learned it overflowed from onLayout, which arrives after the mount has painted on web and Fabric. Every mount (opening the chat, a prompt arriving, a row the list mounts again) painted the text hard-cut with no fade or Show more, then grew the row by the control a frame later. The expanded choice also lived in the row and reset with each remount. Measure the body in a layout effect so the first commit carries the control, and keep the expanded choice in a per-agent store the timeline provides, as tool calls already do.	2026-11-11 08:25:55 +07:00
