Ghostty for Windows 1.0.1

win-v1.0.1 — 2026-04-29

Added

• Horizontal scroll support via WM_MOUSEHWHEEL.
• File drag-and-drop onto a terminal pastes the file path(s), quoting if
  whitespace is present.
• present_terminal action now restores+focuses the window.
• mouse_visibility action toggles the cursor via SetCursor(NULL).
• command_finished flashes the taskbar button on non-zero exit when the
  window is unfocused.
• float_window action sets/clears WS_EX_TOPMOST.
• toggle_visibility hides/shows all top-level windows.
• size_limit action enforces minimum/maximum window dimensions via
  WM_GETMINMAXINFO.
• color_change (OSC 10/11) updates the class background brush so the
  resize-flash matches.
• ring_bell now also flashes the taskbar when the window is unfocused.
• Confirm-close dialog when programmatically closing a tab while a shell
  command is running.
• Built-in ghostty.ico is used for the window icon and tray notifications
  (was the generic Windows app icon).
• New windows cascade 30px from the most recently created window.
• Build option -Dwindows-console=true keeps stderr visible in release
  builds for debugging.
• Title-bar color tracks the configured background on Windows 11 22H2+
  (DWMWA_CAPTION_COLOR), and dark/light chrome is chosen by background
  luminance instead of being hardcoded dark.
• Title-bar chrome refreshes on config reload.
• Clicking the update-available balloon opens the GitHub releases page
  in the user's default browser.
• Update-check requests are rate-limited to once per hour via a
  persisted timestamp at %LOCALAPPDATA%/ghostty/update_check_at.
• VS_VERSION_INFO resource is filled in (Explorer → Properties → Details
  shows real values; signtool tooling has version metadata to attach).
• Application manifest declares UTF-8 active codepage, longPathAware,
  and supportedOS GUIDs for Windows 7 through 11.
• test_window_size_config now hard-fails (was non-blocking) if the
  configured window width didn't take effect.
• test_resize is a real test (was permanently SKIPPED).
• ghostty_test.sh pre-kills leftover processes and retries the exe
  copy once, eliminating intermittent EBUSY in batch runs.

Changed

• Update-check version source is now build_config.version (set by the
  win-v git tag at build time) instead of a hardcoded constant that drifted
  every release.
• Build accepts win-vX.Y.Z tags as a separate version namespace from
  upstream's vX.Y.Z (which still must match build.zig.zon).
• Manifest declares UTF-8 active codepage, longPathAware, and supportedOS
  for Windows 7-11.
• All Win32 bindings use callconv(.winapi) instead of callconv(.c).
  Identical ABI on x64 today; correct WNDPROC type, future-proof for x86.
• DirectWrite locale fallback chain widened: en-US, en-us, en-GB, en before
  index 0.
• DragDropFiles, FlashWindowEx, ShowCursor, GetSystemMetrics,
  SetClassLongPtrW, SIF_TRACKPOS bindings added.
• DrawTextW binding moved from gdi32 to user32 (correct DLL).

Fixed

• C1: cleanupAllSurfaces was deinit'ing a local copy of each SplitTree,
  leaving stale arena pointers; now deinits in place and resets the slot
  to .empty.
• C2: A closing flag is now set before posting WM_CLOSE for the last
  tab; queued mouse/keyboard events are dropped while it's set so they
  can't allocate into a window about to be freed.
• C6: Packaging now includes share/terminfo/ghostty.terminfo (the
  resourcesDir sentinel on Windows). Without it, fresh ZIP installs
  silently failed to load themes.
• C7: Update-check version is now passed via heap pointer through
  WPARAM/LPARAM instead of a static buffer with no fence.
• DirectWrite no longer panics when the factory or system font collection
  is unavailable (Wine, restricted SKUs); discovery returns empty and
  callers fall back to bundled JetBrains Mono.
• ToUnicode scancode mask was 0x1FF; including bit 24 (extended-key flag)
  produced wrong translations for AltGr layouts.
• Palette scroll_offset @intCast could panic when the popup was too
  small to render any items.
• IME ImmGetCompositionStringW byte length now uses @divTrunc with
  parity check instead of @divExact (which would panic on odd input).
• high_surrogate buffer is cleared on focus loss and IME composition
  start so a stray surrogate can't pair with the next character key.
• selectTab(_) clamps the discriminant non-negative before @intCast.
• tab_rects is zero-initialized so input handlers reading it before
  the first WM_PAINT see a no-match instead of stack garbage.
• moveTabTo now cancels any in-progress tab rename.
• paintTabBar brush failures no longer skip the geometry update at the
  bottom of the loop (was piling subsequent tabs on top of the failed
  one).
• QuickTerminal.onWindowDestroyed unconditionally KillTimers the
  animation timer.
• Search/palette popup fonts are rebuilt on DPI change.
• Multi-button mouse capture: SetCapture/ReleaseCapture only run on the
  0→nonzero and nonzero→0 transitions of a button-mask.
• show_child_exited MessageBoxW now actually formats the exit code
  into the body text instead of building it and discarding.
• Desktop and update notifications use distinct (uID, timer-id) pairs so
  one's auto-cleanup doesn't NIM_DELETE the other's icon.
• paintPalette font and bg brush are cached for the popup lifetime
  instead of allocated per repaint.
• Process HANDLE in Command.zig is now CloseHandled on deinit.
• Several upstream features that had been dropped during past merges
  (R1-R9 in the audit) were restored: GHOSTTY_SURFACE_ID env var, the
  processLinks renderer-state mutex, semantic_prompt_boundary in
  link detection, middle-click-action config option, default move_tab
  keybinding, DECBKM mode 67, macOS-only scroll magnitude flooring,
  freetype_windows backend variant, the GHOSTTY_ENUM_TYPED macro and
  GHOSTTY_MODE_REPORT_MAX_VALUE sentinel.
