libghostty v0.0.11

Added

• Color utilities: parseColor, parsePaletteEntry,
  parseX11ColorName, x11ColorNames, palette generation, and luminance
  helpers expose Ghostty's runtime color behavior.
• Unicode width utilities: unicodeCodepointWidth and
  unicodeGraphemeWidth expose Ghostty's terminal cell-width rules.
• Color-scheme reports: ColorScheme.encode() encodes terminal
  color-scheme reporting responses.
• Kitty graphics cache stamps: KittyGraphics.generation and
  KittyImage.generation let renderers detect placement and image cache
  invalidation without comparing image bytes.
• Absolute viewport scrolling: Terminal.scrollToRow() restores viewport
  positions using the same row space as Scrollbar.offset.

Changed

• Kitty graphics pixel data: stored image payloads are exposed as decoded,
  decompressed pixels, including PNG and zlib-compressed transmissions.
• Scrollbar metadata: scrollbar reads use Ghostty's cached offset and
  incrementally maintained total, reducing repeated scrollback traversal.

libghostty v0.0.10

Breaking

• Position coordinates: cursor and grid lookup APIs use Position
  values. GridRef.positionIn() replaces pointIn(), and GridRef
  no longer needs dispose().

Added

• Selection APIs: Selection, SelectionGesture, active terminal
  selection, and selection formatting expose libghostty selection behavior.
• Tracked grid references: TrackedGridRef follows a cell across
  terminal mutations until the referenced cell is discarded.
• Terminal APIs: working-directory changes, device attributes queries,
  default cursor blink, and Glyph Protocol toggling are exposed.
• Render selection metadata: RowIterator.selection and
  CellIterator.isSelected
  expose row-local selection state for render snapshots.

flterm v0.0.4

Breaking

• Selection APIs: selection is backed by libghostty. TerminalSelection
  and TerminalSelectionMode are removed, TerminalConfig.wordPattern
  moves to TerminalGestureSettings.wordBoundaries, and gesture toggles
  are explicit settings.

Added

• Terminal links: TerminalView.linkSettings detects OSC 8 links,
  text URLs, file paths, and custom regex links.
• Controller APIs: selectRange, hasSelection, pwd, and
  onPwdChanged expose selection and working-directory state.
• Glyph Protocol: TerminalConfig.glyphProtocol toggles Glyph Protocol
  APC handling.

Changed

• Rendering pipeline: selection, cursor viewport state, and cell metadata
  use refreshed libghostty render snapshots.

libghostty v0.0.9

Added

• Back-arrow key mode: TerminalMode.backArrowKeyMode() and
  KeyEncoder.setBackArrowKeyMode() expose DEC mode 67, letting legacy
  Backspace encoding switch between DEL and BS.
• APC buffer limits: Terminal.setApcBufferLimit() and
  Terminal.setKittyApcBufferLimit() configure general and Kitty-specific
  APC payload limits.

Fixed

• Resize callbacks: ghostty_terminal_resize is no longer bound as a
  leaf FFI call, preventing callback crashes when resize emits in-band size
  reports through onWritePty.

flterm v0.0.3

Breaking

• Flutter SDK floor: requires Dart 3.12 and Flutter 3.44.

Added

• IME composition: composing text appears at the terminal cursor
  and works with platform text input.
• Sprite glyph rendering: box drawing, block elements, Braille,
  Powerline, geometric shapes, and legacy computing glyphs render
  with built-in glyphs.
• Shared render caches: TerminalScope lets multiple terminal
  views share compatible rendering resources.
• APC buffer limits: TerminalConfig.apcBufferLimit controls how
  much APC payload data the terminal accepts.

Changed

• Rendering pipeline: terminal frames share rendering caches and do
  less repeated work between frames.

Fixed

• Keyboard input: shifted printable keys and IME editing produce
  the expected terminal text.
• Rendering accuracy: erased backgrounds, cursor shape, cell
  metrics, and sprite glyphs render more consistently.

libghostty v0.0.8

Breaking

• Standalone companions: rendering, grid lookups, formatting, and
  encoding moved off Terminal. RenderState with RowIterator /
  CellIterator, GridRef.at, Formatter, KittyGraphics.of, and
  standalone KeyEncoder / MouseEncoder replace their Terminal
  method and getter equivalents.

Added

• Kitty graphics: image and placement lookup with resolved render
  geometry, plus a process-global PNG decoder hook.
• Log callback: process-global sink for the native library's
  internal log output.
• Formatter selection: restrict output to a coordinate region,
  including block selections.
• Terminal data: cursorStyle, isMouseTracking, and Kitty image
  configuration accessors.
• Grid references: hyperlinkUri and pointIn() for OSC 8 lookup
  and coordinate round-tripping.

flterm v0.0.2

Breaking

• Theme colors move into ColorPalette: TerminalTheme no longer
  takes background, foreground, and ansiColors directly. Build a
  ColorPalette once and pass it in, so palettes are something you
  can share, swap, or copyWith on their own.
• Cursor and selection colors can adapt to the cell under them: the
  color fields take DynamicColor? now. Use
  DynamicColor.cellForeground() / .cellBackground() to follow the
  cell, or DynamicColor.fixed(c) for the old static behavior.
• selectedText is a method: call controller.selectedText() for
  plain text, or pass a FormatterFormat to get VT or HTML for
  rich-clipboard copy.
• Bold no longer switches to the bright palette by default: expect
  slightly different bold colors; set boldIsBright: true to restore
  the old behavior.

Added

• Kitty graphics: programs that emit images (previewers, image
  viewers, some editors) render inside the widget. Cap the cache via
  TerminalConfig.kittyImageStorageLimit; zero disables.
• Transparent background: TerminalTheme.backgroundOpacity makes
  the default background translucent so the terminal can compose over
  a translucent window or other widgets. backgroundOpacityCells
  extends it to cells with their own bg color.
• More theme knobs: CursorTheme.text (glyph color under a block
  cursor), TerminalTheme.boldColor (forced bold color), and
  SelectionTheme.foreground (selected-glyph tint).
• ColorPalette.generated(): derives indices 16–255 from your base
  16 plus background and foreground so the extended palette blends
  instead of clashing with the fixed xterm cube.

Changed

• Dirty-row rendering: frames rebuild only rows that changed, so
  idle terminals cost much less CPU.

flterm v0.0.1

Initial Release

• TerminalView: Flutter widget that renders a terminal and adapts input to the host. Mouse and keyboard on desktop, touch and soft keyboard on mobile, both on web.
• TerminalController: owns the terminal and bridges it with the view. Connects to a backend (PTY, SSH, socket) via onOutput, onResize, onBell, and onTitleChanged. Exposes I/O, selection, focus, scrolling, paste, clear, and mode toggling.
• Themes: ANSI 16, 256-color, and truecolor palettes; cursor shape, color, and blink; hyperlink style; font family, size, and fallback; minimum contrast. Immutable and lerp-able.
• Wide characters: CJK, color emoji, VS16, and combining marks render correctly; selection snaps to whole cells.
• Mouse selection: drag, double-click word, triple-click line, and Alt+drag block.
• Shortcuts: built-in copy, paste, select all, and clear with platform-aware defaults.
• OSC 8 hyperlinks: idle and highlighted styles with click hit-testing.
• Cross-platform: Android, iOS, Linux, macOS, Web (WASM), Windows.

libghostty v0.0.7

Fixed

• Linux prebuilts: the prebuilt Linux binaries failed to load on glibc
  systems with invalid ELF header. They now ship as
  libghostty-x86_64-linux-gnu.so and libghostty-aarch64-linux-gnu.so,
  properly linked against glibc.

libghostty v0.0.6

Added

• ARGB color accessors: Cell.backgroundArgb and Cell.foregroundArgb
  return resolved colors as packed 32-bit ARGB ints, or null if unset.
  Callers handle the default themselves.
• RgbColor.toArgb32: convert an RgbColor to a packed 32-bit ARGB int
  with full opacity.
• Cell.graphemeLength: number of codepoints in the cell's grapheme
  cluster (0 for empty cells).

Changed

• Cell hot path: codepoint and wide are cached during row iteration
  to eliminate per-access FFI calls in the renderer hot loop.
• Row hot path: the raw row pointer is cached and invalidated when the
  iterator advances to a new row.

Fixed

• VS16 emoji width: multi-codepoint graphemes are no longer misclassified
  as narrow based on their first codepoint. The wide-cell fast path now only
  applies to single-codepoint cells, so an emoji base followed by VS16 is
  correctly marked wide.
• Wide-codepoint heuristic: replaced the hand-rolled Unicode range table
  in the wide-cell fast path with a single >= U+1100 check. The old table
  could mark some wide CJK codepoints as narrow without consulting the FFI
  width query.
