+# Liney Electron Preview 0.1.5
+
+Liney 0.1.5 wires AppImage auto-update to GitHub Releases and cleans up the
+About page so an up-to-date install simply says so and stops.
+
+## Highlights
+
+- **GitHub update feed:** packaged AppImage builds resolve the update feed
+  from `Cytech-Team/Liney` releases out of the box (`latest-linux.yml` +
+  `.blockmap` with SHA-512/signature metadata). No manual feed URL needed;
+  `LINEY_UPDATE_FEED_URL` remains as a self-hosted generic-feed override.
+  Preview and Stable stay separate via stable releases vs prereleases.
+- **Up-to-date UX:** when no update is available, About reports the latest
+  version and ends — no stale "new version" subtitle, no leftover
+  release-notes or error blocks.
+- **English UI coverage:** full English localization alongside Thai, with
+  automatic selection from the system locale and a manual switch in Settings.
+- **Native editing shortcuts:** Ctrl+A/C/V/X (including Thai input) verified
+  in packaged builds.
+- **Portable package verification:** Linux package checks no longer depend on
+  a host RPM database, and Talk sync waits for readiness before disabling
+  polling fallback.
+
+## Linux downloads
+
+The release pipeline publishes x86_64 AppImage, DEB, RPM, and Flatpak
+packages, now including the `latest-linux.yml` update metadata and blockmap
+for AppImage auto-update. Native GUI and packaged-worker smoke checks run in
+CI; Flatpak build output is verified before publication.
+
+## Notes
+
+Liney is an independent, unofficial desktop client for LINE and is not
+affiliated with or endorsed by LINE Corporation.
