chore: point README at Gitea releases; build-windows.ps1 mirrors pubspec version

Two rotate drags started quickly at nearly the same spot were treated as a
double click: the reset was detected on button down against the previous down
time/position, so it wiped all effects and ignored the second drag, leaving
Ctrl+S to save an unrotated crop.

- Double click is now only counted for actual clicks (movement <= 4px) and is
  decided on button up; a drag breaks the chain.
- Pointer up is matched by pointer id, so a left-drag pan never counts as a click.
- dist: 1.7.2 .deb replaces the tracked 1.7.1 package.

 ## [Unreleased]
 
+## [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
