App

New

• Turkish interface: OpenChamber can be used in Turkish (thanks to @fitzgpt).
• Worktrees: a session menu can move an idle session and its sub-sessions into an existing worktree. OpenChamber finds worktrees created elsewhere, asks before carrying uncommitted changes over, and keeps those changes safe if the move fails partway (thanks to @mattv8).
• Composer: pasting a big block of text, about 2,000 characters or 25 lines, offers to attach it as a pasted-context-N.txt file and leaves a [pasted-context-N.txt] reference at the caret. Settings → Chat can make it always attach or always paste inline (thanks to @makeittech).
• Work status: a session's cost includes what its subagents spent, split under the context meter and shown per subagent (thanks to @igorvelho).
• Multi-Run: a group can hold more than five models, including isolated runs that make one worktree per model (thanks to @tomzx).
• Projects: the folder picker can select several directories at once and add them together (thanks to @herjarsa).
• Files: the Markdown preview has an in-document search (Ctrl/Cmd+F) with highlighting and next/previous (thanks to @makeittech).
• Panels: right-click an editor, chat, or browser tab to close it, close others, close left or right, or close all (thanks to @adavila0703).
• Chat: a tool card with a file path has a quick-open button (thanks to @robertoberto).
• Mobile: Android connections can trust user-installed certificate authorities, such as a local proxy's (thanks to @Silvenga).
• Debug: the debug panel (Ctrl/Cmd+Shift+D) has a Requests tab showing in-flight requests and their age over the last five minutes (thanks to @tomzx).

Improvements

• Chat: the text the model writes before it asks a question appears right away instead of waiting in the Activity group until the turn ends (thanks to @makeittech).
• Usage: GitHub Copilot shows a single AI Credits window matching Copilot's token-based quota, in place of the Chat Requests and Completions windows (thanks to @jakoss).
• Files: files up to 20,000 lines open in the full-file preview, up from 5,000 (thanks to @gaojunran).
• Mobile: Chats, the sessions that belong to no project, appear in the sessions sheet above the project list.
• Projects: the folder picker can step into a directory that is already a project and browse from there (thanks to @weixiang1862).
• Web/PWA: the installed app uses the shorter name "OpenChamber" (thanks to @bketelsen and @greghaynes).
• Sidebar: Recent rows show a compact timestamp on web and desktop.

Fixes

• Chat: a very large tool result is capped before it renders, so it no longer freezes the page (thanks to @JSap0914).
• Chat: a code block with JavaScript template strings no longer sends the syntax highlighter into endless backtracking (thanks to @makeittech).
• Chat: a diff with a truncated header no longer crashes the conversation (thanks to @pascalandr).
• Chat: a draft or recalled message with Windows line endings no longer throws "Selection points outside of document" every time you open it (thanks to @yulia-ivashko).
• Chat: a session no longer looks frozen after a page reload or a late second client. Pending permission and question cards come back (thanks to @yangyaofei).
• Chat: a session no longer looks frozen after you dismiss the agent's questions and send a new task (thanks to @bashrusakh).
• Chat: when the turn-ending signal from OpenCode is lost, the working spinner clears within about a second instead of up to ten (thanks to @makeittech).
• /btw side questions: a btw session answers the side question instead of carrying on with the parent's plan, and it forks at the last completed turn, so it never inherits a reply that is still streaming (thanks to @pocharlies).
• Composer: typing three backticks leaves the caret inside the finished code fence, an empty input keeps a visible caret, and platform autocorrect behaves as it should (thanks to @franzudev, @TTTPOB, and @IbrahimKhan12).
• Chat scrolling: with "Follow new content while streaming" off, sending from the middle of a conversation no longer jumps to the new message.
• Chat scrolling: a middle-button pan or Shift+Space stops auto-follow the way the wheel does, and an upward wheel inside a tool output box scrolls that box instead of the chat (thanks to @pascalandr).
• Chat scrolling: PageUp/PageDown in the prompt box no longer shifts the whole window up and hides the title bar.
• Chat: question prompts render Markdown (thanks to @pascalandr).
• Chat: a bare link next to CJK or full-width punctuation no longer swallows it (thanks to @gaojunran).
• Chat: inline code and chips are readable in every theme (thanks to @difagume).
• Chat: a finished reasoning block shows in full instead of replaying as if it were still thinking, the text-selection menu stays inside the window, and the sticky user-message header no longer fades over the first lines of the reply (thanks to @makeittech).
• Chat: sending without a selected model says what is missing (thanks to @rvaldemar).
• Chat: /init stays in slash-command autocomplete after the conversation starts (thanks to @Dawnfz-Lenfeng).
• Chat: copying a message keeps Markdown paragraph, list, and code-block spacing (thanks to @ChangeHow).
• Chat: Ctrl/Cmd+digit is ignored while you type in a field, and a model you picked by hand survives switching between Build and Plan (thanks to @makeittech).
• Chat: a message made only of quoted context fragments appears in the prompt navigator.
• Chat: opening or closing the context panel no longer leaves a blank tail under the last message.
• Files: a file reached through a symlink inside the workspace, or under a project root that is itself a symlink, opens again instead of failing with an access error (thanks to @herjarsa).
• Files: clicking a folder or file in the sidebar tree opens it reliably on macOS trackpads, where a tiny pointer move used to swallow the click (thanks to @makeittech).
• Browser: when the agent captures a page while the browser panel is hidden, the panel is revealed first instead of the capture failing.
• Work status: undoing or redoing a parent session keeps its subagents at the same point in history (thanks to @alexandrereyes).
• Mobile: opening an agent that is already open switches to its editor instead of duplicating it (thanks to @bashrusakh).
• Sidebar: searching sessions also finds Chats, the sessions that belong to no project, which used to vanish as soon as you typed (thanks to @yulia-ivashko).
• Sidebar: pending permission and question badges are no longer covered by the hover actions (thanks to @makeittech).
• Projects: sending, forking, and image attachments work in projects whose path has non-ASCII characters, such as Masaüstü (thanks to @fitzgpt).
• Web/PWA: a notification click focuses an existing window (thanks to @bketelsen and @greghaynes).
• Themes: custom themes loaded through symlinks work (thanks to @divyam234).
• Plans: a saved plan opens with its content again for chats, worktrees outside the project path, and tabs restored after a reload, and an edit made right before closing is no longer lost.
• Settings: the editor font size survives a restart (thanks to @pascalandr).
• Settings: a change made right before you close the window is saved (thanks to @makeittech).
• Settings: number fields and selects no longer clip at large font sizes (thanks to @makeittech).
• Settings: refreshing GitHub account state no longer interrupts the page (thanks to @floze-the-genius).
• Settings: the Cloudflare Tunnel download link works (thanks to @AyoubAchour).
• Settings: Windows skill paths are classified correctly, so disabled and duplicate skills are hidden as intended (thanks to @Ttungx).
• Settings/Providers: after you save an API key or sign in, the provider no longer shows "Credentials missing" with its models hidden until you switch away and back (thanks to @herjarsa).
• Small model: requests send the provider's configured headers, such as an API-gateway subscription key (thanks to @dmitrii-galantsev).
• Small model: a configured Anthropic endpoint is used without a doubled /v1, and Google models without reasoning no longer get a thinking option (thanks to @mpeter and @IngTian).
• Git: the status panel refreshes from the real repository after checkout, branch, stash, merge, rebase, or reset, and remote branches that were never fetched appear in branch lists (thanks to @makeittech).
• Git: the Branch diff scope compares against the right base for branches created from the current branch (thanks to @gaojunran).
• Git: picking origin/main in the branch selector checks out the local branch instead of a detached HEAD (thanks to @yulia-ivashko).
• Git: branch search hides branches that do not match (thanks to @bashrusakh).
• Updates: "Update OpenCode" no longer fails with a bare "Bad Request". OpenChamber names the release it will install and shows OpenCode's reason when it refuses (thanks to @mdatsev and @yulia-ivashko).
• Updates: the desktop "Restart to Update" button says why an install failed, including an unsigned local build, and stays available to retry (thanks to @mdatsev and @yulia-ivashko).
• Desktop: a crashed window recovers on its own, and repeated crashes end in a visible failure page instead of a reload loop (thanks to @wqpan).
• Desktop: a slow or interactive shell startup file no longer stalls startup while OpenChamber looks for OpenCode. Each probe gives up after five seconds, which is what left a Homebrew OpenCode looking undetected from a Dock launch (thanks to @mskadu).
• Windows: restarting managed OpenCode cleans up orphaned listeners and process trees, closing the app stops OpenCode, and scheduled startup no longer fails on Task Scheduler's command length limit (thanks to @sergiofspedro, @a0000001, and @HAHH9527).
• Windows: startup cleanup of leftover processes no longer blocks the server (thanks to @bashrusakh).
• Server: an OPENCODE_BINARY from the environment is kept when settings.json clears its own override (thanks to @bashrusakh).
• Server: recovery through OPENCODE_HOST keeps the configured host and port (thanks to @colinmollenhour).
• Server: openchamber connect-url no longer risks tearing settings.json while the desktop app runs, which could unpair every device (thanks to @shijie152).
• Sessions: switching quickly no longer saves the wrong scroll position, and the log no longer fills with worktree warnings for folders that are not Git repositories (thanks to @herjarsa).
• VS Code: the extension starts in the current workspace folder instead of one restored from storage (thanks to @makeittech).

VS Code

New

• Turkish interface: OpenChamber can be used in Turkish (thanks to @fitzgpt).

• Multi-Run: a group can hold more than five models (thanks to @tomzx).
• Chat: a tool card with a file path has a quick-open button that opens the file in the editor (thanks to @robertoberto).

Improvements

• Context usage reports a session's cost including everything its subagents spent (thanks to @igorvelho).
• Chat: the text the model writes before it asks a question appears right away instead of waiting until the turn ends (thanks to @makeittech).

• Chat: a session no longer looks frozen after you dismiss the agent's questions and send a new task (thanks to @bashrusakh).
• Chat: when the turn-ending signal from OpenCode is lost, the working spinner clears within about a second instead of up to ten (thanks to @makeittech).

• Chat scrolling: with "Follow new content while streaming" off, sending while scrolled up leaves the view where it is, and a middle-button pan or Shift+Space stops auto-follow the way the wheel does (thanks to @pascalandr).
• Chat scrolling: PageUp/PageDown in the prompt box no longer shifts the whole panel up.
• Chat: question prompts render Markdown (thanks to @pascalandr).
• Chat: a bare link next to CJK or full-width punctuation no longer swallows it (thanks to @gaojunran).
• Chat: inline code, chips, and model-picker highlights stay readable in high-contrast themes (thanks to @difagume and @bashrusakh).
• Chat: a finished reasoning block shows in full instead of replaying, the text-selection menu stays inside the window, and the sticky user-message header no longer fades over the reply (thanks to @makeittech).

• Settings: number fields and selects no longer clip at large font sizes (thanks to @makeittech).
• Settings: Windows skill paths are classified correctly, so disabled and duplicate skills are hidden as intended (thanks to @Ttungx).
• Windows: closing VS Code stops the managed OpenCode process instead of leaving it running (thanks to @a0000001).
• Work status: undoing or redoing a parent session keeps its subagents at the same point in history (thanks to @alexandrereyes).
