+
+## Highlights
+
+- Open external URLs using the active connection's browser profile for consistent session isolation
+- Keep the app accessible on macOS with a system tray icon when the window is closed
+- Sync zoom level between the main window and all open tool BrowserViews
+- Allow tools to open mailto: links with explicit user consent and URL validation
+- Improve protocol handler behavior for stable builds (single-instance lock and safer registration rules)
+- Make marketplace filtering clearer with an active-filter indicator and one-click clear
+- Improve tool update availability visibility with a clearer text-based indicator
+- Zoom: correct zoom-in accelerator keys and re-fit BrowserView bounds after zooming
+- Links: avoid lowercasing full URLs during mailto: scheme checks
+- Links: improve parse-failure logging with scheme context while avoiding PII
+- Tools sidebar: improve empty-state hint behavior for better guidance
+- URLs: add support for URLs ending in mcas.ms where applicable
+- macOS: ensure tray Quit fully exits the app (track isQuitting correctly)
+- toolboxAPI: remove deprecated loading screen API and associated handlers
+- pptb-validate: validate pptb.config.json invocation with semver enforcement
+- Types: rename PptbConfig → PPTBConfig and validatePptbConfig → validatePPTBConfig for consistent casing
+- CI/CD: separate stable vs insider release channels (including channel-specific icons)
+- Windows packaging: sign app binaries before packaging into installers
+- Workflows: tighten merge automation with explicit permissions and concurrency
+- Windows: Power-Platform-ToolBox-1.2.2-Setup.exe
+- macOS: Power-Platform-ToolBox-1.2.2.dmg (drag to Applications)
+- Linux: Power-Platform-ToolBox-1.2.2.AppImage (chmod +x, then run)
+- No manual migration needed; existing settings and connections continue to work.
+- Tool developers: mailto: opening may prompt for user consent; update config/type references to PPTBConfig if you used the older casing.
+
+## Fixes

+- UI: fix notification layering/z-index issues in the renderer
