- Settings 'Size' section: 8 col x 4 row grid, 31 buttons labeled a:b
  (a splits H, b splits W); top-left cell empty placeholder (no 1:1 —
  title bar double click already maximizes)

  display's work area (screen_retriever visibleSize, taskbar excluded);
  position unchanged, no selection state tracking
- minimumSize 400x300 -> 160x100 (4:8 cell needs it)

 ## [Unreleased]
 
+## [1.9.0] - 2026-10-31
+
+### Added
+- Taskbar/alt-tab title now shows the opened image's file name (falls back to
+  "imajViewer" when no image is open).
+- Full hicolor icon size set (16–256 px) instead of only 64 px, so small-icon
+  contexts (Thunar "Open With", Xfce app menu) keep the symbol visible.
+
+### Changed
+- `install.sh` generates the full icon size set and rewrites the hicolor
+  index; uninstall hint updated.
+- Settings size grid is now a fixed 4-column layout (the wide/narrow
+  transposition introduced in this release was removed).
+
+## [1.8.0] - 2026-10-31
+
+### Added
+- Window size presets: 4×8 screen-ratio grid in settings; clicking a preset
+  resizes the window to that fraction of the screen work area (taskbar
+  excluded). Minimum window size lowered to 160×100.
+
+### Fixed
+- Settings file-properties rows were centered under the longest row (path);
+  now left-aligned.
+
+## [1.7.2] - 2026-10-25
+
+### Fixed
+- Rotating sometimes vanished before saving: the right-button double-click reset was
+  detected on button *down* against the previous down time and position, so two rotate
+  drags started quickly at nearly the same spot were treated as a double click — all
+  effects (rotation included) were wiped and the second drag was ignored, so `Ctrl+S`
+  saved an unrotated crop. A double click is now only counted for actual clicks
+  (movement ≤ 4 px, decided on button up), a drag breaks the chain, and
+  `pointer up` is matched by pointer id so a left-drag pan never counts as a click.
+
+## [1.7.1] - 2026-10-25
+
+### Added
+- Zoom percentage badge at the bottom center, between the previous/next buttons: shown
+  together with the hover controls, translucent background, live while wheeling
+  (100% = one image pixel per screen pixel), recomputed on fill/fit toggle, image
+  change and window resize.
+
+### Changed
+- Image header parsing (pixel size without decoding) moved from the viewer screen into
+  `lib/services/image_header.dart`; the settings file-properties panel and the zoom badge
+  use the same code.
+
+## [1.7.0] - 2026-10-20
+
+### Added
+- Settings dialog shows the app version next to the name.
+- Fine zoom: `Ctrl`+wheel zooms 1% per step (plain wheel stays 10% per step).
+- Settings shortcut list completed: `Ctrl+O` (open), `Esc` (exit fullscreen), scroll/zoom,
+  `Ctrl`+scroll fine zoom, left-drag pan, double right click (reset effects).
+
+### Changed
+- README: zoom feature line and shortcut table updated to match.
+
+## [1.6.3] - 2026-10-20
+
+### Fixed
+- `SIGSEGV` while resizing the window. The GTK embedder's OpenGL compositor uploaded the frame using
+  the window's new dimensions while its pixel buffer still held the previous size, so `memcpy` read
+  past the end of the buffer (`engine/.../linux/fl_compositor_opengl.cc`). Fixed upstream in
+  flutter#187626, which is not part of Flutter 3.44.7 — the Linux build now uses Flutter 3.47.7,
+  where the compositor derives the texture size from the framebuffer itself.
+
+## [1.6.2] - 2026-10-14
+
+### Changed
+- Crop save JPEG quality raised from 93 to 95.
+
+## [1.6.1] - 2026-10-14
+
+### Fixed
+- Horizontal flip shortcut (`Ctrl+R`) never fired when the keyboard layout resolves the R key to a
+  different logical key (reported with a Turkish/remote-desktop setup where the R key arrives as
+  logical `T`). The shortcut now matches the physical R key position as well.
+
+## [1.6.0] - 2026-10-14
+
+### Added
+- Horizontal flip (`Ctrl+R`): mirrors the image left-right about the viewport centre and clears
+  the active effects (same reset as double right click); pressing `Ctrl+R` again restores the
+  original orientation. Zoom/pan are kept.
+- Crop save (`Ctrl+S`) now bakes the flip into the output as well, so the saved JPEG matches
+  the mirrored view (also in combination with rotation).
+
 ## [1.5.0] - 2026-10-12
