Power Platform ToolBox 1.2.2

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
UI: fix notification layering/z-index issues in the renderer
Tools sidebar: improve empty-state hint behavior for better guidance
Marketplace: fix tool icon theming so icons adapt correctly in light/dark mode
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

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.
