 # Changelog
 
+## 0.1.65-beta.1 - 2026-04-29
+
+### Added
+
+- Images in assistant messages show a loading spinner while they load and an "Image unavailable" fallback if they fail, instead of a blank space.
+
+### Fixed
+
+- **Apple Silicon Mac:** The desktop update pipeline now publishes manifests atomically, closing a race that could install the Intel build on Apple Silicon Macs and cause 100%+ renderer CPU usage. Affected users will self-heal — electron-updater's Rosetta detection migrates back to arm64 on the next update poll. ([#555](https://github.com/getpaseo/paseo/issues/555))
+- **Linux:** `.deb` and `.rpm` packages now show as `Paseo` in the dock and process list instead of `Paseo.bin`. `--no-sandbox` is now scoped to AppImage only, matching VS Code's sandbox handling. ([#602](https://github.com/getpaseo/paseo/issues/602))
+- `paseo.json` parse errors in setup, teardown, and terminal actions now surface a clear error instead of failing silently.
+- Diff gutter line numbers were shifted one row out of alignment in some cases on web.
