Power Platform ToolBox 1.2.7

Highlights

Select a Dataverse user to impersonate for a tool instance and see when impersonation is active.
Assign tools up to ten positional connection slots, including optional slots, and route requests to the selected environment.
Send additional Dataverse request headers after consent, with persistent approvals available for review and revocation.
Run independent Dataverse operations in one batch or group writes in an atomic transaction.
Connect declared .NET worker processes through a typed API with managed startup, requests, cancellation, and shutdown.
Use the refreshed workspace layout with a custom title bar, sidebar controls, full-screen mode, and split-pane tool placement.

Improved multi-connection selection responsiveness and clarified connection assignment in the picker.
Preserved positional connection assignments, including empty slots, across restore, duplication, deletion, and tool updates.
Added paged Dataverse user search for impersonation selection.
Kept modal dialogs above the main window on Linux and constrained long notification messages.
Restored missing log recording and improved telemetry scrubbing of sensitive fields.
Corrected Dataverse header consent so instance approvals remain limited to the active tool instance.

Added features.connections declarations, numeric connection targets, slot-aware APIs, and positional MCP connectionNames.
Added dataverseAPI.executeBatch and executeTransaction, with request validation, consent checks, and per-operation results.
Added the typed toolboxAPI.workers.connect interface, .NET runtime/package handling, native-execution consent, and JSON-RPC process lifecycle.
Added Dataverse impersonation APIs and user-search support for tool authors.
Updated title-bar, full-screen, and split-layout controls across the renderer and main-process IPC bridge.

No manual migration needed; existing connection declarations and primary/secondary APIs remain supported.
.NET worker support is opt-in; Windows/Linux and packaged-app qualification remains outstanding.
