Two fixes for escape-focus flakiness on VMs:
1. App-side: recordGotoSplitUITestWebViewFocus now retries with increasing
delays (0.05, 0.1, 0.25, 0.5s) for the exit-address-bar case, giving
WebKit more time to accept first responder.
2. Test-side: both testEscapeLeavesOmnibarAndFocusesWebView and
refocusWebView helper send a second Escape if the first only clears
suggestions/editing state (Chrome-like two-stage escape behavior).
In fullscreen mode, the NSTitlebarAccessoryViewController buttons are hidden
with the system titlebar. This adds SwiftUI-based fullscreen controls that
appear in the sidebar area (when visible) or inline in the custom titlebar
(when sidebar is hidden), reusing the existing TitlebarControlsView component.
- Track fullscreen state via window notifications and toggle controls visibility
- Hide original titlebar accessory (isHidden + alphaValue=0) in fullscreen
- Route notification popover anchoring through fullscreen controls view model
so both button clicks and keyboard shortcuts (Cmd+Shift+I) position correctly
- Add debug titlebar spacing slider for fine-tuning leading inset
resolveTabForReport only searched the active window's tab manager, so
report_ports, report_git_branch, report_pwd, set_status etc. returned
"Tab not found" when the shell's --tab UUID belonged to a different
window. Fall back to AppDelegate.tabManagerFor(tabId:) to search all
window contexts.
* Open cmd+clicked terminal links in cmux browser panel instead of system browser
Handle GHOSTTY_ACTION_OPEN_URL in the Ghostty action callback to intercept
link opens. Uses preferredBrowserTargetPane to reuse an existing right-side
pane, falling back to a new horizontal split.
* Use tab-specific manager for OPEN_URL action
Use tabManagerFor(tabId:) instead of the active-window tabManager so the
lookup succeeds when the surface belongs to a different window context.
* Add "+" menu button to horizontal tab bar for new terminal/browser tabs
Adds a "+" button to the tab bar (next to split buttons) that shows a
dropdown menu with "New Terminal ⌘T" and "New Browser ⌘⇧L" options.
- Uses native NSButton + NSMenu so the icon matches the split buttons
- Menu appears below the button
- Routes tab creation through new didRequestNewTab delegate method

* Fix multi-workspace drag/drop, WebView click focus, and add regression tests
- Wire bonsplit isInteractive to workspace active state so inactive
workspace NSViews are hidden from AppKit event routing
- Add CmuxWebView.mouseDown notification for browser panel focus
tracking (AppKit delivers clicks to WKWebView, not SwiftUI overlays)
- Add multi-workspace focus regression test covering isHidden fix,
rapid workspace switching, and browser panel focus routing
* Bump version to 1.36.0
The 3-second safety net that posts a synthetic mouseUp to break out of
NSTextView's stuck tracking loop was dispatched on the main queue. Since
super.mouseDown blocks the main thread in the tracking loop, the timeout
could never fire. Use a background queue instead (NSApp.postEvent is
thread-safe). Use DispatchWorkItem.isCancelled for atomic cancellation.
* Fix terminal keys (arrows, Ctrl+N/P) swallowed after opening browser
After a browser panel is shown, SwiftUI's internal focus system activates
and its _NSHostingView starts consuming arrow keys and other non-Command
key events via performKeyEquivalent, preventing them from reaching the
terminal's keyDown handler.
Fix: In the NSWindow performKeyEquivalent swizzle, when GhosttyNSView is
the first responder and the event has no Command modifier, route directly
to the terminal's performKeyEquivalent — bypassing SwiftUI's view hierarchy
walk entirely.
Also clear stale browserAddressBarFocusedPanelId when a terminal surface
has focus, preventing Cmd+N from being eaten by omnibar selection logic
after focus transitions away from a browser.
Adds DEBUG-only keyboard event ring buffer (KeyDebugLog) that dumps to
/tmp/cmux-key-debug.log for diagnosing future key routing issues.
* Fix split focus and Cmd+Shift+N swallowed after opening browser
Split focus: capture the source terminal's hostedView before bonsplit
mutates focusedPaneId, so focusPanel moves focus FROM the old pane
instead of from the new pane to itself. Also retry ensureFocus when the
new terminal's view has no window yet (matching the existing retry
pattern for isVisibleInUI).
Cmd+Shift+N: after WKWebView has been in the responder chain, SwiftUI's
internal focus system can intercept Command-key events in the content
view hierarchy (returning true) without firing the CommandGroup action
closure. Fix by dispatching Command-key events directly to NSApp.mainMenu
when the terminal is first responder, bypassing the broken SwiftUI path.
Also add Cmd+Shift+N to handleCustomShortcut so it's customizable and
doesn't depend on SwiftUI menu dispatch at all.
* Unified debug event log: merge key/mouse/focus into /tmp/cmux-debug.log
- Delete KeyDebugLog, MouseDebugLog, klog(), mlog() from AppDelegate
- Replace all klog/mlog calls with dlog() (provided by bonsplit)
- Remove debugLogCallback wiring from Workspace
- Add focus change logging: focus.panel, focus.firstResponder,
split.created, focus.moveFocus
- Add import Bonsplit where needed for dlog access
- Fix stale drag state on cancelled tab drags (bonsplit submodule)
* Fix split focus stolen by re-entrant becomeFirstResponder during reparenting
During programmatic splits (Cmd+D / Cmd+Shift+D), SwiftUI reparents the old
terminal view, which fires becomeFirstResponder → onFocus → focusPanel for the
OLD panel, stealing focus from the newly created pane.
Add programmaticFocusTargetPanelId guard to suppress re-entrant focusPanel
calls for non-target panels during split creation.
Also document the unified debug event log in CLAUDE.md.
* Clear stale title/favicon when browser navigation fails
When a page fails to load (e.g. connection refused), the tab was still
showing the previous page's title and favicon. Now didFailProvisionalNavigation
resets pageTitle to the failed URL and clears faviconPNGData.
* Fix Cmd+N swallowed by browser omnibar and improve split focus suppression
- Only Ctrl+N/P trigger omnibar navigation, not Cmd+N/P (Cmd+N should
always create new workspace regardless of address bar focus)
- Move split focus suppression from workspace-level guard to source:
suppress becomeFirstResponder side-effects (onFocus + ghostty_surface_set_focus)
directly on the old GhosttyNSView during reparenting, preventing both
model-level and libghostty-level focus divergence
- Remove programmaticFocusTargetPanelId from Workspace.focusPanel
* Fix omnibar hang, WebView white flash, drag-over-browser, and idle CPU spin
- Omnibar: first click selects all without entering NSTextView tracking loop;
subsequent clicks have 3s synthetic mouseUp safety net to prevent hang
- WebView: set underPageBackgroundColor to match window so new browsers don't
flash white before content loads
- Drag/drop: register custom UTType (com.splittabbar.tabtransfer) in Info.plist
so WKWebView doesn't intercept tab drags; override registerForDraggedTypes
on CmuxWebView as belt-and-suspenders
- CPU: fix infinite makeFirstResponder loop in controlTextDidEndEditing by
checking both the text field and its field editor (the actual first responder)
* Fix menubar lag in production builds caused by hardened runtime
Hardened runtime's library validation was verifying every dylib on load,
causing noticeable UI lag. Add entitlements file with
disable-library-validation to fix while keeping notarization support.

Move GeometryReader from wrapping the entire VStack to wrapping only the
ScrollView so proxy.size.height reflects available height (minus pill),
preventing unnecessary scrollability that triggered macOS horizontal insets.
Also clamp update pill text width with maxWidth instead of fixed width so
it truncates gracefully at narrow sidebar widths and grows when wider, add
horizontal padding, left-align truncated text, and add debug menu item for
testing with long nightly version strings.
- Sidebar now shows git branch, listening ports, log entries, progress bars, and status pills with expand/collapse
- Fix localhost/127.0.0.1 URL parsing by checking before generic URL(string:) which misinterprets the scheme
- Remove custom Keychain distinct ID in favor of PostHog SDK's built-in anonymous ID
- browser open now defaults to caller's workspace via CMUX_WORKSPACE_ID env var
- Improve CLI help text for environment variables
- Change Cmd+[/] from workspace history navigation to browser back/forward
(only when focused surface is a browser, no-op on terminal)
- Add WKUIDelegate with createWebViewWith to handle target=_blank links
- Add decidePolicyFor check for targetFrame==nil and cmd+click modifier
to open links in new browser surface in the same pane
- Override willOpenMenu in CmuxWebView to rename "Open Link in New Window"
to "Open Link in New Tab"
- Add E2E test for browser back/forward via socket and Cmd+[/] shortcuts
Instead of creating a merged config directory and injecting
CLAUDE_CONFIG_DIR on every terminal spawn, place a thin wrapper
script at Resources/bin/claude that intercepts claude invocations
to inject --session-id and --settings flags. This eliminates
blocking I/O on terminal creation and removes config management
complexity.
- Add Resources/bin/claude wrapper script with hook injection
- Add shell integration PATH fix (re-prepend after .zshrc/.bashrc)
- Add transcript reading for richer stop notifications
- Add set_status/clear_status to notifications socket allowlist
- Add Settings toggle to disable Claude Code integration
- Update docs to reflect automatic integration approach
- Unset CLAUDECODE env var to avoid nested session detection
