+# v0.2.10
+
+Follow-up patch release for v0.2.9 addressing regressions in the auto-updater flow.
+
+## Bug Fixes
+
+- Fix update progress dialog freezing / not repainting — progress callbacks now run on the UI thread so the download and extraction percentage actually updates while an update is in progress
+- Fix pre-update backup failing when a Serilog-held log file is locked — `UpdateBackupService` now enumerates files manually, skips the `logs/` directory and `.log` files, and logs-and-continues on `IOException`/`UnauthorizedAccessException` instead of aborting the whole backup
+- Simplify update progress dispatch — remove redundant `Application.Invoke` wrappers around progress updates that are already called from the UI thread (introduced while fixing the freeze above)

 ## Bug Fixes
 
 - Fix Linux/macOS client install — enable single-file publish so the install script copies one self-contained binary instead of just the native host (which failed with "does not exist: EchoHub.Client.dll")
+- Fix Chocolatey install path on Windows — `chocolateyInstall.ps1` was joining the install directory and executable name into a single segment, producing an invalid target path
+- Fix Chocolatey package metadata — corrected GitHub repository URLs and documentation URLs in `echohub.nuspec` that pointed at the wrong location
+- Fix double-click on "Public" checkbox in the Create Channel dialog accidentally submitting the dialog — checkbox toggle commands no longer bubble up to the dialog's default button
+
+## Documentation
+
+- Add a dedicated configuration guide (`docs/articles/configuration.md`) covering server settings, client settings, and environment overrides
+- Refresh README badges and reorganize the articles table of contents for better discoverability
+- Polish Docker, getting-started, and flow docs to match the current configuration surface
+
+## Dependencies
+
+- Bump `Terminal.Gui` to `2.0.0-develop.5043` (from `5039`)
+
+## CI
+
+- Release workflow now publishes a single-file self-contained client binary for Linux and macOS so the install script works out-of-the-box
+- Chocolatey publishing step now triggers only when the package source actually changes and performs a proper version check against the feed before pushing
