 ## v0.4.2 (2026-04-22)
 
+### Bug Fixes
+- Ship previously-missing package assets in release artifacts — prebuilt notification sounds (`alert`, `bell`, `chime`, `ping`, `pop`) and game adapter YAMLs (`minecraft`, `rocket_league`, `valorant`). An unanchored `data/` rule in `.gitignore` was matching `server/src/ledgrab/data/`, so these files never reached the tag or CI builds. Also bump the `_FALLBACK_VERSION` literal to `0.4.2` so the Windows installer (which strips `.dist-info`) reports the correct version in the WebUI instead of `0.3.0`. Build scripts now patch this literal automatically to prevent future drift. ([5db6edd](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/5db6edd))

 ### Features
 - Restyle the enhanced header locale picker as a LED-accent badge — 2-letter code in Orbitron, collapses to just the badge on narrow screens ([9ce1dc3](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/9ce1dc3))

 #### CI/Build
 - Publish `.sha256` sidecars alongside release assets for easier integrity verification ([03d2e6b](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/03d2e6b))
 
+#### Refactoring
+- Move the Key Colors test out of the lightbox and into the `test-css-source` modal where the rest of the source-render debug tools live ([be2d5e1](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/be2d5e1))
