+  download progress bar, then set them as your Home screen, Lock screen, or both. Installed
+  wallpapers are cached on-device so they're available fully offline afterwards.
+- **Gallery** - community screenshots and visual archive, with a pinch-to-zoom/swipe fullscreen
+  viewer, download-all, per-image share, and offline fallback to the last fetched copy.
+- **Documentation** - the full official HackerOS documentation, parsed and rendered **natively**
+  (no WebView) straight from the website's own data file, with a native tab menu, native search,
+  offline caching, and an English-only-content notice where relevant.
+- **Games Store** - browse, install, update, and launch community-made games for HackerOS, right
+  from the app (HackerOS-App acts as the manager/installer for the shared community game catalog).
 - **Team** - meet the people behind HackerOS.
-- **Settings** - 10 languages, 8 selectable themes (Monochrome by default), release
-  notifications, and in-app update checks.
+- **Settings** - 10 languages, 12 selectable themes (Monochrome by default) plus a custom theme
+  builder, release notifications
+  (with per-edition filtering), in-app update checks with a full download/verify/install flow, and
+  toggles to hide the Documentation and/or Games Store sections entirely.
+- **Self-updating** - checks for new app versions, downloads the APK with a live progress bar,
+  verifies it against a published checksum when available, then hands off to the system installer.
+- **What's new** - a short summary of the latest release is shown once right after updating the
+  app.
+
+## What's new in v0.6
+
+- **4 new built-in themes**: Ultraviolet, Cool Mint, Blackout Rose, and Steel Blue - alongside the
+  existing 8.
+- **Create your own theme.** A new custom theme builder in Settings lets you pick Primary,
+  Background, and Card colors from a curated swatch grid or an exact hex code, with a live
+  preview, and save it as a selectable theme of your own.
+- **Translation audit fix**: several strings across the app (the Team screen description, a
+  handful of Settings labels, status badges, and a couple of toast messages) were hardcoded in
+  English regardless of the selected app language. All of these now respect the language setting
+  across all 10 supported languages.
+
+## What's new in v0.5.2
+
+- **Documentation is now fully native - no WebView.** The app parses the website's own
+  `translations/hackeros-documentation.js` data file directly (including a small tolerant
+  JS-object-literal-to-JSON converter, since that file isn't strict JSON) and renders it with
+  native Compose UI: tab menu, native search, headings, lists, code blocks with copy buttons,
+  and the tools/programming reference content - mirroring the website's own renderer
+  (`doc-engine.js`) field-for-field so the content matches exactly.
+- **New Games Store section.** HackerOS-App now acts as a manager for community-made phone games,
+  reading a shared catalog (`games-store/community-games.json` in this repo) and letting you
+  browse, install (with a live progress bar and checksum verification, just like app updates),
+  open, or update each game - all without leaving the app.
+- **Documentation and Games Store can each be hidden** from Settings if you don't want them
+  cluttering the navigation bar.

+## Reliability / offline
+
+- Releases and the gallery are cached locally (DataStore) after every successful fetch; if a
+  later fetch fails (no connection), the app shows that last-known-good data instead of an error
+  screen, with a small "offline" banner so it's clear the data isn't live.
+- Installed wallpapers are cached in app-private storage, so they remain viewable/settable fully
+  offline after the first successful install.
+- The in-app Documentation WebView is configured to fall back to its HTTP cache when there's no
+  connection, so a previously-opened page can still be read offline.
+
+## In-app updates
+
+- Settings now offers a full update flow: check → download (with a live % progress bar) → verify
+  (SHA-256 checksum, when the release publishes one) → install via the system Package Installer,
+  all without leaving the app.
+- Release notifications can be filtered per HackerOS edition (Official, Cybersecurity, NVIDIA,
+  etc.) instead of firing for every edition.
+- A "What's new" dialog summarizes the latest release once, right after an app update.
+
 - CI: added `.github/workflows/build.yml`, which builds signed-ready debug and release APKs via
   Gradle and publishes them as a downloadable `outputs` artifact.
+- CI/build fix: the repo was missing `gradle/wrapper/gradle-wrapper.jar` entirely (so `./gradlew`
+  could never even start Gradle), `gradlew` itself contained a broken self-download hack pointing
+  at a URL that doesn't host the compiled jar, and a committed `local.properties` hardcoded a
+  developer's personal SDK path - which silently overrode the CI runner's own Android SDK and
+  broke every build. All three are fixed: a genuine wrapper jar + the standard official
+  `gradlew`/`gradlew.bat` scripts are now committed, `local.properties` is generated fresh by the
+  workflow (and gitignored), and the workflow no longer uses a third-party Android SDK setup
+  action (GitHub's runners already ship one, license-accepted) - which was the actual cause of
+  the workflow hanging/"waiting" indefinitely. The job also now has a hard 30-minute timeout as a
+  safety net.
