What's Changed

Fixed

• Python setup crash "Exit code: 9 - bad option: --js-flags" (#61): the dependency installer no longer inherits Electron-specific flags from the host IDE.
• Empty output panel despite successful do-file execution (#62): streaming execution now writes to the exact log file the stream monitors, with a fallback that emits the final result directly if log tailing produced nothing.
• User log using commands broken by output capture (#63): the server now captures output through its own named log (__mcp_log) and never touches user logs; log using/log close in your do-files work as in native Stata. If your code runs log close _all, MCP capture automatically resumes.
• Port reclaim failed on non-English Windows (#64): all three port-cleanup paths are now locale-independent (netstat parsing without state-word matching in Python; PowerShell Get-NetTCPConnection in the extension and standalone launcher). IPv4+IPv6 covered.
• workingDirectory setting now honored in multi-session mode (#36), including the none option.
• Interactive window works behind path-prefixing proxies (#54) — relative URLs instead of root-relative.
• Data Viewer no longer materializes the full filtered dataset before applying the row limit (related to #59).

Changed

• Session log filenames use a sanitized session id + short hash (prevents invalid filenames/path traversal).
• MCP stata_run_selection accepts timeout, working_dir, and session_id; timeouts enforced server-side in single-session mode.
• Compact output mode strips Stata log header/footer noise from selection results.
• start-server.js forwards --log-file-location / --custom-log-directory.
• Temporary preprocessed do-files are cleaned up on all execution paths.

What's Changed

Graph Viewer Rewrite (Issue #60)

• Stable webview shell with message-based (postMessage) hydration — no more full-document replacement on every update
• External CSS/JS assets loaded with nonce-based Content Security Policy, matching Microsoft's recommended webview pattern
• Execution-scoped graph artifacts — each batch lives under its own directory with a manifest, so graph1.png / graph2.png no longer overwrite each other across runs
• Graph state centralized in a dedicated GraphStore on the extension side
• Webview resource paths resolved through fs.realpathSync, so images load correctly on filesystems with symlinks or reparse points (macOS /private/var, Linux symlinked /tmp, Windows OneDrive, cloud-synced install locations)

Fixed

• "Already preserved r(621)" error (Issue #58): Data Viewer filter no longer touches the user's preserve stack — replaced with isolated frame copy
• Session restart recovery: users stuck in the r(621) state can recover via "Restart Stata Session"
• Help endpoint if/else syntax error: fixed malformed Stata code in HTML help lookup
• View Data toolbar button overflow: added explicit navigation@N ordering so the button stays visible
• Graph viewer black-screen / missing content (Issue #60): resolved by the webview rewrite and path-resolution changes above; also added defensive onerror handling and server-side file-size validation for empty/corrupt PNG exports

Hardened

• Session manager: explicit session_id requests no longer silently reroute; execution timeouts recover the session in place; dead default sessions are now recovered; non-execution timeouts no longer reset a session unnecessarily

Tests

• New tests/test_graph_artifacts.py covering execution-scoped artifact layer
• Rewrote tests/test_notifications.py and tests/test_streaming_http.py to make real assertions when a local integration server is available and skip cleanly otherwise
• Expanded tests/test_session_manager.py for the session hardening changes

Full Changelog: v0.5.1...v0.5.2

What's Changed

Fixed

• Streaming output not displaying in Cursor/Trae (Issue #57): Force Node.js HTTP adapter for streaming requests to prevent axios from selecting the incompatible XHR adapter in VS Code forks

Full Changelog: v0.5.0...v0.5.1

What's Changed

Interactive Window as VS Code Panel (Issue #54)

• New setting stata-vscode.interactiveDisplayMode: choose panel (default) to open the Interactive Window as a VS Code webview tab, or browser for external browser
• Panel mode executes code and displays output/graphs inline with interactive command input

Fixed

• Interactive Window URL broken in code-server: asExternalUri() was stripping the /interactive path in proxied environments. Fixed by resolving the base URL first, then re-appending path and query.
• Graph viewer scrolling lockup: Added proper overflow CSS and capped graph history at 50 entries to prevent unbounded DOM growth.
• Same asExternalUri fix applied to external browser graph display URLs.

Full Changelog: v0.4.9...v0.5.0

What's Changed

Help Command Support (Issue #55)

• Type help regress, man logit, h merge, etc. via Run Selection or the Interactive Window to display Stata help in a dedicated webview panel
• Rich SMCL rendering — full formatting with bold, italic, command styling, proper fonts and colors (matches Stata's native Viewer)
• Clickable links — click any help reference to navigate to that topic
• Back/Forward navigation with history
• Table of contents from {viewerjumpto} entries for quick section navigation
• "Also see" section with clickable related topics
• Synopt tables rendered as proper HTML tables
• VS Code theme-aware — adapts to light and dark themes
• Supports help, man, chelp, whelp commands (including abbreviations)
• Handles multi-word topics, #-prefixed topics, and options
• MCP tool calls (AI agents) are NOT affected

Note: The help interception works when a single help command line is selected and run. If help is embedded inside a longer do-file or multi-line selection, it goes through normal Stata execution.

Full Changelog: v0.4.8...v0.4.9

What's Changed

Fixed

• Graphs Fail in Remote Environments (Issue #54): Fixed graph display in code-server, Remote-SSH, and proxied environments
  • Replaced http://localhost image URLs with webview.asWebviewUri() for loading graphs from disk
  • Added proper localResourceRoots to webview panels
  • Updated Content Security Policy to use webview.cspSource
  • External browser display now uses vscode.env.asExternalUri() for correct URL resolution
• Path traversal protection on /graphs/ HTTP endpoint
• Graph output parsing fixed for lines with [CMD: ...] suffix
• Null reference guard in interactive panel when closed during async operation
• HTML escaping hardened for graph names, URLs, and file names

Full Changelog: v0.4.7...v0.4.8

What's Changed

Added

• Restart Stata Session command — reset the Stata session to a clean state from the editor toolbar, context menu, or Command Palette. Equivalent to closing and reopening Stata.

Fixed

• Globals and macros lost between runs (Issue #51) — removed overly aggressive capture program drop _all and capture macro drop _all from the Run File wrapper. Sequential workflows now work correctly: run config.do to define globals, then analysis.do can access them.
• Windows trailing backslash path issue (Issue #52) — fixed working directory path handling when path ends with \.

Full Changelog: v0.4.6...v0.4.7

What's Changed

Added

• Data Viewer Large Dataset Support: Efficient virtual scrolling for handling up to 500K rows
  • Only renders visible rows (~50-100 DOM elements) instead of all rows
  • Smooth scrolling experience even with large datasets
  • New setting stata-vscode.dataViewerMaxRows (default: 100K, max: 500K)
  • Warning: Setting above 500K may cause slow loading due to JSON transfer size

Fixed

• Row Number Display After Filtering: Row numbers now correctly show original Stata observation numbers

  • Previously showed sequential numbers (1, 2, 3...) after filtering
  • Now displays actual observation numbers from original dataset (e.g., 10, 25, 50...)

• Number Formatting in Data Viewer: Fixed regex escaping issue in template literals

  • Trailing zeros now correctly removed from decimal numbers

• Data Loading with obs Parameter: Fixed pdataframe_from_data(obs=...) usage

  • Efficient row limiting without data copying

Full Changelog: v0.4.5...v0.4.6

What's Changed

Fixed

• MCP Tool Name Too Long: Fixed 400 error caused by auto-generated tool names exceeding API length limits (Issue #48)
  • Hidden streaming endpoints (/run_file/stream, /run_selection/stream) from MCP schema
  • Streaming endpoints remain functional for HTTP but are no longer exposed as MCP tools
  • Prevents invalid_request_error when using Claude Code or other MCP clients

Full Changelog: v0.4.4...v0.4.5

What's Changed

Fixed

• HTTP Protocol Error on Windows: Fixed h11 "MUST_CLOSE" error during streaming execution (Issue #45)

  • Restructured run_selection_stream to match run_file_stream approach
  • Moved temp file cleanup from generator's try-finally to worker thread
  • Prevents protocol violations when client disconnects mid-stream

• Unwanted .cursor Directory Creation: Fixed extension creating .cursor/mcp.json in VS Code (Issue #45)

  • Added IDE detection using vscode.env.appName
  • MCP config auto-update now only runs when using Cursor IDE
