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

v0.8.0

New Features

• Context-Aware Autocompletion in Collection View: The filter, project, sort, and aggregation editors now provide schema-aware field suggestions, type-aware operator ordering, hover documentation, real-time syntax validation, and relaxed query syntax (unquoted keys, BSON constructors, JavaScript expressions). #508, #506, #513, #518
• Query Playground: Introduces .documentdb.js files for writing and running JavaScript scripts against your cluster with CodeLens execution (per-block and Run All), console.log()/print()/printjson() support, per-file connections, and autocompletion for db.* chains and schema fields. No external tools required: the runtime is bundled and works with Entra ID. #508, #573, #589
• Interactive Shell: A full REPL terminal in VS Code with shell commands (show dbs, use <db>, help, it, exit), persistent eval context (variables carry over between commands), syntax highlighting, tab completion with ghost text, Ctrl+C cancellation, and clickable result links. Bundled runtime, no external tools needed, works with Entra ID. #508, #573, #576, #580
• Cross-Feature Navigation: Collection View, Query Playground, and Interactive Shell are linked with toolbar buttons, CodeLens actions, clickable terminal links, and clipboard copy/paste for seamless query movement between surfaces. #589
• About Dialog: Adds an "About" entry to the Help & Feedback view with extension version, VS Code version, OS details, and registered plugins, plus a Copy button for bug reporting. #612

Improvements

• Query Insights: Static Analysis: Improved performance evaluation with selectivity and fetch overhead metrics, three-color badge system, index strategy advisories, and edge case fixes. AI analysis now aligns with static analysis to avoid contradictions. Demoted score for single-field bitmap indexes on high-selectivity queries. #615, #616, #623
• Double-Click to Open Collection View: The Documents tree item now requires a double-click to open the Collection View, preventing tabs from opening accidentally on single-click browse.
• Custom Editor Tab Icons: Collection View, Document View, and Query Playground tabs now display dedicated icons instead of the default webview icon.
• Telemetry: Simplified and standardized telemetry instrumentation across connection, discovery, shell, and playground features. #601, #544, #599
• Internal Package Rename: Renamed internal packages to @documentdb-js scope for consistency. #613
• Prerelease Version Migration: Implemented migration for prerelease version handling in notifications. #610

Fixes

• Duplicate Connection Reveal: Fixed an issue where revealing a duplicate connection failed when the connection was inside a folder. #602

Dependencies

• Dependency Updates: Updated fast-uri, fast-xml-builder, basic-ftp, path-to-regexp, fast-xml-parser, and @aws-sdk/xml-builder. #624, #606, #607, #609, #627, #628, #629

v0.7.4

New Features & Improvements

• URL-Encoded Password Detection: When a connection attempt fails and the password contains URL-encoded characters, the extension now offers a "Retry with Decoded Password" option. If the retry succeeds, the decoded password can be saved. #444, #594
• Rich Markdown Tooltips: Cluster, database, and collection tree items in the Connections view now show rich markdown tooltips on hover, displaying useful details (host, auth method, document count, storage size) without requiring expansion or connection. #579, #588
• Copy Reference Context Menu: Adds a "Copy Reference…" right-click option to database, collection, and index nodes with a QuickPick format picker. Databases offer name, shell command (use dbName), or qualified name; collections offer name, namespace, shell reference, or db.getCollection() form; indexes offer name, key definition, or shell command. Names with special characters automatically use safe escaping. #545, #587

Documentation

• Improved CONTRIBUTING.md: Adds a PR submission checklist, corrects Node/npm version requirements, and adds multi-platform setup stubs. #565

Dependencies

• Dependency Updates: Bumps handlebars (4.7.8 → 4.7.9), lodash (4.17.23 → 4.18.1), lodash and @microsoft/api-extractor in /api, and follow-redirects (1.15.11 → 1.16.0). #552, #556, #558, #586

v0.7.3

New Features

Improvements

• Dependency Updates: Upgrades Node.js from 20 to 22 and bumps undici, handlebars, brace-expansion, picomatch, and flatted to their latest versions. #523, #534, #537, #539, #541, #542
• Telemetry Improvements: Refines connection and discovery action telemetry with more specific, actionable diagnostic properties. #544

v0.7.2

Improvements

• Data Migration Discoverability: The "Data Migration…" menu is now always visible on cluster nodes and introduces announced providers infrastructure to help users discover and install migration extensions from the Marketplace. #515
• Reconnect Prompt After Credential Update: Offers a reconnect prompt when updating credentials from an error recovery node, so users no longer need to manually retry the connection. #504
• Experimental AI Query Generation Setting: Adds documentDB.experimental.enableAIQueryGeneration setting to control the AI query generation feature, disabled by default. Reports experimental feature status via activation telemetry. #503
• tRPC Upgrade and Abort Signal Support: Upgrades @trpc/client and @trpc/server to v11.10.0 and adds AbortSignal-based cancellation for webview operations. #320, #502
• Connection String Validation: Adds defensive trimming (including BOM, NBSP) at all input entry points and simplifies credential validation to avoid unnecessary parse/serialize round-trips. #511
• Feedback Collection Documentation: Documents how the extension collects user feedback and its relation to VS Code's global telemetry setting in the README. #509

Security

• Dependency Updates: Updates minimatch (3.1.2 → 3.1.4), qs, and body-parser to address security vulnerabilities. #505, #514
