 ### Improve
 
+## 3.2.0
+
+### Breaking
+
+### Improve
+
+* fix(hangul): revert [#719] — pass keys (layout symbol/number layers such as the sebeolsik shifted right-half) are committed in Hangul mode again instead of being bypassed to the application. Shortcut-modified keys (Ctrl/Alt/Super) have no layout entry and are already passed through by the caller, so the special-case bypass was unnecessary and regressed every Hangul layout. [#754](https://github.com/Riey/kime/issues/754)
+* Replace cmake build system with meson
+  - cargo builds via `custom_target()`, GTK/Qt frontends as `shared_library()`
+  - Per-component build options (gtk3, gtk4, qt5, qt6, check, indicator, etc.), enabled by default
+  - `kime` and other binaries build by default when running `ninja`
+  - `system_engine` mode for building frontends against system-installed engine
+  - Qt plugin dir override options for nix compatibility
+* Remove EOL distro Dockerfiles (ubuntu 18.04~22.10, debian buster)
+* Add debian-trixie Dockerfile
+* Update release workflow: Qt5/Qt6 multi-version matrix builds, softprops/action-gh-release@v2
+* nix: switch to fetchCargoVendor, parameterize frontend toggles
+* Fix mismatched cargoDeps in nix and update attribute syntax **[@nakoo]**
+* Updated NixOS configuration example to match updated attribute syntax.
+* Remove `kime-engine-cffi`
+* fix(wayland input_method_v2): not return unwarp **[@racakenon]** [#715](https://github.com/Riey/kime/715)
+* feat(engine): Let default `Alt_R` hotkey accept `Alt` modifier [#719](https://github.com/Riey/kime/719)
+* fix(hangul): Don't consume pass keys (numbers, symbols) so app shortcuts like `@`/`#` fire in Hangul mode [#719](https://github.com/Riey/kime/719)
+* Add Opensuse Build Service repository and modify README
+* fix(xim): handle None from from_hardware_code without panic [#721](https://github.com/Riey/kime/721)
+* Update dependencies:
+  - wayland-client 0.29 → 0.31, wayland-protocols 0.29 → 0.32
+  - wayland-protocols-misc 0.3 (신규), xdg 2.5 → 3.0, quick-xml 0.27 → 0.39
+  - xkbcommon 0.7 → 0.9, ksni 0.2 → 0.3.3 + tokio
+  - bitflags 2.10, nix 0.30, strum 0.27
+  - x11rb 0.13, xim 0.5, image 0.25, imageproc 0.26
+  - mio 1.0 with timerfd-mio, egui/eframe 0.33, itertools 0.14
+  - bindgen 0.72.1, cbindgen 0.29.2
+  - Replace rusttype with ab_glyph
+  - Replace ansi_term with owo-colors
+  - Replace daemonize with nix daemon
+  - Replace unic with unicode-properties
+* Remove unused dependencies:
+  - Remove zwp-virtual-keyboard (merged into wayland-protocols-misc)
+* Fix kime-wayland crash on KDE Plasma 6.5.5 by handling KeyState::Repeated
+* Fix indicator tray icon not showing/updating on KDE with tokio async I/O (ksni 0.3.3)
+* Rewrite kime-wayland for wayland-rs 0.31 API (Dispatch trait pattern)
+* fix(xim): degrade gracefully when the preedit font is missing instead of panicking [#706](https://github.com/Riey/kime/issues/706)
+* feat(engine): add `SuperL`/`SuperR` keycodes so Right-Super can be bound as a hotkey [#640](https://github.com/Riey/kime/issues/640)
+* fix(hangul): enable `ComposeJongseongSsang` by default for sebeolsik-3sin-p2 (ㄲ 받침) [#646](https://github.com/Riey/kime/issues/646)
+* fix(latin): repair the malformed Dvorak layout so it parses and works [#626](https://github.com/Riey/kime/issues/626)
+* fix(hangul): Sebeolsik composition bug when typing `v` instead of `/` [#679](https://github.com/Riey/kime/issues/679)
+* Qt6 immodule: append `.5.1` suffix to the plugin IID so it builds without `qt5-base` installed (fixes Arch/AUR build) [#732](https://github.com/Riey/kime/issues/732) [#736](https://github.com/Riey/kime/pull/736)
+* Add `qt5` dependency to fix the frontend build failure on Arch Linux [#724](https://github.com/Riey/kime/pull/724)
+* Release: build Qt6 immodules per-version like Qt5 and add Qt 6.9 / 6.10 to the build matrix [#749](https://github.com/Riey/kime/pull/749)
+* Packaging: include gtk4 and qt6 immodules in the `.deb` packages, including ubuntu-22.04 [#734](https://github.com/Riey/kime/issues/734) [#750](https://github.com/Riey/kime/pull/750)
+* Build Dockerfiles for Ubuntu 24.04 and Debian Bookworm [#726](https://github.com/Riey/kime/pull/726)
