Power Platform ToolBox - Release v1.2.5
Watch the release highlights and walkthrough for this version.
Highlights
- Private Marketplace supports multiple sources, source filters, author details, and restart prompts when settings change.
- CSP consent review shows current permissions, records approval history, and requests consent again when tools add permissions.
- Headless MCP execution provides job status, invocation details, log clearing, and client configuration status.
- MCP Server can remain running while tools open or reopen, supporting background headless workflows.
- Installed tool details and context menus include repository links and clearer analytics rating values.
- Connection setup adds a Configure App flow for Power Platform API app registrations.
- Telemetry consent messaging explains collection and restart behavior more clearly.
Fixes
- Connections: selecting an environment URL after enabling Power Platform API no longer loses focus to a native confirmation dialog.
- Connections: app registration guidance and Copy Script messaging are clearer and more consistent.
- Tools: CSP consent is recalculated correctly when required or optional domains change.
- Analytics: download and MAU updates use atomic operations and preserve existing metrics when errors occur.
- Logging: Error objects retain their original stack traces in structured logs.
- Windows: release workflows generate and bundle
app-update.ymlmetadata so auto-update artifacts are complete. - Build validation: package version checks use the correct
@pptb/typesand@pptb/validatepaths.
