May 13 Release

This release covers everything since v0.59.2: a new multi-project rail, a richer structured-prompt tool for AI agents, Codex parity work, and a long list of fixes across the editor, AI pipeline, and platform support.

New Features

• Multi-project rail. A new Discord-style vertical rail lets a single Nimbalyst window host several workspaces side-by-side, with instant switching. Inactive projects stay warm: AI sessions keep streaming, file watchers keep firing, transcripts keep updating, and tabs/panel layouts are preserved per project. Cmd/Ctrl+1..9 activates the Nth project; Cmd/Ctrl+Shift+W closes the active one. Right-click a rail icon for "Open in new window", "Reveal in Finder/Explorer", and "Close project". Enable it under Settings > Advanced > General > "Multi-project Mode".
• Show Tool Calls in Chat toggle. A new Agent Features setting (default on) lets you hide tool-call rows in the AI chat entirely, not just collapse them. Interactive prompts (permission requests, plan-mode exits, commit proposals, AskUserQuestion) still appear so you can always respond.
• PromptForUserInput MCP tool. Agents can now collect several inputs at once through a single structured-prompt widget with five field types: multi-select, single-select, reorder, edit-text, and confirm. Voice mode honors a voiceFriendly hint and defers to the screen for long drafts or large reorders.
• Rename AI sessions, plus Preferred Agent Language. Sessions can now be renamed (right-click an existing session). A new "Preferred Agent Language" setting on the Agent Features panel steers AI-generated session names toward your chosen language for both Claude Code and other providers.
• Voice mode improvements.
  • Voice agent can now run "Commit with AI" via a new propose_commit voice tool. The same Requesting Commit Proposal widget appears in the transcript and you can approve or reject by voice.
  • Voice agent can create a coding session on demand; the new session becomes the active linked session automatically.
  • "Generate Project Summary" now launches a new agent session in your configured agent (Claude Code, Codex, etc.) instead of requiring an Anthropic API key.
  • Voice Mode settings surface microphone permission status with a deep link to System Settings on macOS.
• Codex parity.
  • Codex file_change tool calls now render as inline red/green edit cards in the transcript, matching how Claude's Edit tool already renders.
  • Codex slash command autocomplete and a unified slash-command picker across Claude Code and Codex.
  • Skills and commands written for one agent run in the other; workflow discovery is unified across providers.
  • Codex reasoning items map into transcript thinking blocks.
• Slash skill namespacing. Plugin skills are now namespaced consistently with commands (e.g. /excalidraw:excalidraw, /planning:design, /feedback:bug-report) so the inserted command matches what the agent SDK routes.
• MCP servers run on Electron's bundled Node. MCP servers configured with command: "node" now use Electron's bundled Node runtime, so MCP features work out of the box on fresh installs without a system-wide Node.js install.
• List recent sessions by title only. The list_recent_sessions MCP tool now accepts searchField: 'title' | 'content' | 'both' so agents can find a session by name even when the search term appears throughout conversations.
• Tracker tracker_update can change the primary type. A task that turns out to be a bug can now be reclassified without losing comments, attachments, or session links.
• Markdown anchor links scroll to in-document headings. Clicking [Section](#section) in a Lexical document now scrolls to the matching heading. (#248)
• PDF export metadata. Markdown-to-PDF export now writes the document title and generates an outline from headings, so exported files are bookmarked and the title shows in PDF readers.
• Peek file diffs from the git log commit detail. Click a file in a selected commit's detail panel to pin its unified diff in the peek popover; Up/Down steps through files; Esc closes.

Improvements

• Slow startup is visible. A new always-on [StartupSlow] {phase} took {ms}ms log line is emitted whenever startup phases (PGLite init, project file sync, session index sync, etc.) cross 2 seconds, so beach-ball reports surface a concrete phase.
• Lexical 0.44 upgrade. Editor packages are upgraded to Lexical 0.44.0 across the runtime.
• Lexical extension API. Extensions can now ship Lexical editor extensions (custom nodes, transformers, commands, and React UI surfaces) through a new manifest field.
• Codex SDK upgrade. Bundled @openai/codex-sdk upgraded to 0.128.0; Claude packaged binary resolution hardened so agent sessions stay on bundled or explicit custom binaries.
• Session list refresh is faster. The session list no longer scans the full edit history on every refresh, and concurrent refreshes share one query.

Fixed

• Tray icon on Linux and Windows. The system tray entry now appears on Linux AppImage and Windows builds; previously only macOS showed the tray. (#39)
• Multi-file drag-and-drop. Dragging a multi-selection of files in the file tree now moves or copies every selected item, with a single summary error dialog if some fail. Previously only the first file was moved. (#31)
• Claude Chat connection to Claude Opus 4.7. Test Connection (and real chat sends) no longer fail with temperature is deprecated for this model on the default claude-opus-4-7 model. (#199)
• Frontmatter detection on Windows CRLF files. Files checked out with core.autocrlf=true are now correctly detected as Tracker items, automations, and other frontmatter-typed documents. (#68)
• Ctrl+= zoom on Windows and Linux. Pressing Ctrl+= (without Shift) now zooms in; numpad +/- and Shift+= also work. (#205)
• Honor .gitignore in nested git repos. Workspaces containing nested git repos no longer OOM the main process by walking into ignored directories of the nested repo. (#207)
• Git status for files in nested repos. Files committed inside a nested git repo no longer report as untracked indefinitely. (#122)
• Custom Claude Code binary path. The Claude Code path setting in AI Models is now read correctly instead of always falling back to the bundled SDK binary. (#162)
• Auto-update error spam suppressed on hourly polls. Transient network errors (net::ERR_NAME_NOT_RESOLVED, timeouts, refused connections) during the hourly auto-update check no longer pop a toast; manual "Check for Updates" still surfaces errors and download errors still surface mid-download. (#56)
• Restore open workspaces after auto-update relaunch. "Restart and Install" no longer leaves the app with zero workspaces open. (#232)
• Environment Variables setting restored to user scope. The panel reads/writes the global ~/.claude/settings.json, so it no longer appears under the Project tab where it implied workspace-scoped state. (#185)
• Delete file errors surface to the UI. When a file delete fails (e.g. non-writable trash folder on Linux), the file tree now opens an error dialog with the OS-level reason instead of silently logging. (#195)
• Commit proposal widget improvements.
  • Failures now render an actual error state with the reason; previously every failure (hook rejection, no staged changes, IPC throws) was collapsed into "cancelled". (#202)
  • The commit proposal widget reliably appears in the transcript instead of waiting for the user to cancel. (#265)
  • Deleted files are now staged alongside additions and modifications in commit proposals.
  • Files in the commit proposal are sorted alphabetically within each directory, with subdirectories grouped. (#233)
• Open tabs are no longer lost when switching tasks/sessions/files. A race where the saved tab list was overwritten with an empty list before workspace state had hydrated is fixed. (#169)
• Cross-window session pollution stopped. Streaming sessions in one window no longer produce Rejecting session ... belongs to /A, not /B warnings in sibling windows.
• Stream-closed errors during long Claude Code turns reduced. The SDK stdin now stays open across late tool permission requests on multi-result turns (e.g. compaction). (#160)
• Default Claude OAuth subscription traffic. Fresh installs now classify Pro and Max OAuth traffic correctly so it is not silently deprioritized by Anthropic's backend. (#174)
• Show platform-correct keyboard shortcuts. Windows and Linux now show Ctrl+... shortcuts instead of macOS glyphs across menus and the Keyboard Shortcuts dialog. (#149)
• Paste-as-Text is reliable and discoverable. Cmd/Ctrl+Shift+V detection is normalized in the AI input and the shortcut is listed in the Keyboard Shortcuts dialog.
• Voice mic stays open after each turn. The 15-second listen window now starts when audio playback drains in your speakers (not when the server finishes streaming); function-call-only turns also wake the mic; a short readiness cue plays when the mic wakes with no audible reply.
• tracker_create no longer auto-links the calling AI session. Agents must pass linkSession: true (or call tracker_link_session afterward), so sessions don't accumulate unrelated tracker items.
• Pasting images on Windows. Pasting an image into a markdown document on Windows no longer fails with a nim-asset 403 due to mixed path separators.
• Markdown round-trip fidelity.
  • Triple-nested emphasis (e.g. ~~strike *italic **bold** text* inside~~) is preserved on export.
  • Bold spans containing inline code stay intact through approve-all diff round-trips.
  • Sub-bullet diffs with auto-linked URLs no longer duplicate or orphan rows.
• Inline diff readability. Near-complete paragraph rewrites fall back to a block-level diff instead of interleaving red/green word fragments; identical opening or closing sentences are peeled off the diff.
• Editor refreshes on AI edits even when the pre-edit event outruns the disk write. Tabs no longer freeze on the pre-edit content while disk has the new bytes.
• Restoring from history on a gitignored file. The editor no longer shows stale content until you reopen the tab.
• Agent-mode conflict dialogs. The dialog caps at viewport height with an internal scroll so header and Close/Resolve buttons stay reachable on short viewports; the dialog also widens to fit conflict file lists.
• Read-only Codex bash commands no longer attribute as edits. A read-only sed -n or cat on a file with uncommitted modifications no longer produces a phantom "edited" row.
• Lazy HEIC decoder. Standard PNG/JPEG image attachments no longer pay the HEIC wasm startup cost; HEIC is only decoded when actually needed.
• Tracker items from automation files appear on the board. Files using automationStatus frontmatter now show as Tracker rows. (#67)
• Legacy plan and decision tracker docs appear on the board. Files saved with the older top-level planStatus / decisionStatus frontmatter are restored to the Tracker view.
• Tracker "+ Launch Session" uses the workspace's default provider. Codex-only installs no longer hit "Provider claude-code is not enabled for this workspace". (#176)
• Built-in editor file types in extension AI tools. Filesystem-only tools (e.g. automations) no longer fail with "No custom editor registered..." when invoked against a built-in editor's file (e.g. a .md file owned by Lexical). (#217)
• Sub-session renames live-update. Renaming a sub-session via right-click updates its title immediately; workstream parent rows also gain inline rename support. (#211)
• Stable left-pane child counts. Adding a child session (e.g. from /launch-new-session) reveals the new child in the workstream tree without a manual disclosure toggle.
• Codex sessions show child output in meta-agent results. get_session_result now extracts lastResponse, recentMessages, userPrompts, and originalPrompt for Codex sessions, not just Claude.
• iOS transcript renders late-turn Codex tool calls. Cross-turn Codex item id reuse no longer drops tool calls; Codex and ACP/Copilot CLI providers now route through their own parsers on mobile.
• Shared mockup viewer rendering. Standalone shared mockup pages bundle the right styles and no longer crash; mockup diff review is re-enabled for .mockup.html editors.
• Walkthrough callouts. Wide callouts no longer overflow the viewport edge or point past their target.
• Claude session imports with workspace paths containing spaces or special characters. The import path now matches Claude Code's path encoder, so sessions resolve to the right on-disk directory. (#170)
