v0.8.1

New Features

• Item Counts on Tree Nodes: Database nodes now display a live collection count, and the Indexes folder shows an index count. Counts load asynchronously without blocking tree expansion. A new documentDB.accessibility.hideCountPrefix setting hides the ·· visual separator for accessibility or aesthetic preference. #714, #658, #659
• AI Model Transparency in Query Insights: Query Insights now discloses which model processed the request and confirms upfront that the utility model does not count against the GitHub Copilot premium request quota. A model attribution byline ("Powered by {model} via GitHub Copilot") appears after each successful analysis. #690
• Batch Connection Deletion: Multi-select connections in the Connections View and delete them all in one command. The confirmation message adapts to the count, deletion continues on individual failures, and a summary is reported on completion. #667

Improvements

• Performance: Faster Connection Load and Startup: Significant startup speedup, especially on Remote-WSL and large connection lists. Connections now load concurrently; a short-lived cache coalesces redundant reads; startup cleanup is gated to run once per version, not every launch. Also removes the legacy one-time Azure Databases extension connection import. Note: users who had un-imported connections in ms-azuretools.vscode-cosmosdb will need to re-add them manually. #726
• Performance: Throttled Background Document-Count Fetches: A per-cluster concurrency limiter now caps simultaneous background count requests at 5 with a 250 ms inter-task delay, preventing connection pool saturation when expanding databases with many collections. #685
• Shard Key in Collection Tooltip: Sharded collections now show their shard key in the hover tooltip. Extracted from the existing listCollections() response at no extra cost. #670, #661
• Contextual Query Playground Filenames: New playground files opened from the tree now use context-derived names (e.g., cluster_collection.documentdb.js) with invalid-character sanitization and numeric suffixes for duplicates. #664, #660
• _id_ Index Sorted First: The _id_ index now always appears at the top of the Indexes list regardless of other index names and locale sort order. #662, #657
• credentialId → clusterId Parameter Rename: Renamed the credentialId parameter to clusterId in ClustersClient and ClusterSession for naming consistency. Community contribution by @CalvinMagezi, @Jah-yee, and @Enocko. #652, #567
• Hidden Index Tree Item: Hidden indexes now show a hidden description label and only the appropriate context menu action (Hide or Unhide, not both). The _id_ index shows neither action. #674, #656
• Removed Obsolete Notification Migration Code: Cleaned up pre-0.7.0 transitional release-notes logic and leftover 0.8.0-bugbash migration paths. #622, #611

Fixes

• Node 24 Compatibility: VS Code 1.123 (released June 3, 2026) ships with Node 24, which broke extension loading. Updated @microsoft/vscode-azext-utils (~3.3.1 → ~4.1.0) and @microsoft/vscode-azext-azureutils (~3.4.5 → ~4.2.0) to restore compatibility. #699

Dependencies

• Dependency Updates: Updated webpack-dev-server (5.2.3 → 5.2.4, CORP security header fix), @nevware21/ts-utils (0.13.0 → 0.14.0 in root and /api), and qs/express to their latest versions. #654, #672, #673, #678
