Release 0.35.0

SysML v2.0 Extension v0.35.0

Fixed

• DFA snapshot coverage — expanded warmup text with prefix metadata (#Safety, #Security), nested action def inside part def, then state succession shorthand, and nested subviews; regenerated DFA snapshot eliminating false parse errors for these constructs
• False invalid-constraint-body warning in viewpoints — require constraint { doc /* ... */ } inside viewpoint bodies no longer flagged as invalid
• view-showcase.sysml syntax — corrected entry state idle to state idle in OperatingStates state def

Release 0.34.0

SysML v2.0 Extension v0.34.0

Added

• SysML v2 View/Viewpoint support — views with expose, filter, and render directives now drive the visualizer dropdown and diagram selection
• Boolean filter expressions — filter directives support or, and, not, and parenthesised grouping (e.g. filter @PartUsage or @PortUsage)
• Textual notation renderer — render asTextualNotation displays scoped elements as monospace SysML text with coloured keywords and click-to-navigate
• Subview hierarchy — nested view usages shown with ↳ indent in the dropdown; parentView tracked through the element tree
• View definition inheritance — view usages inherit filter, render, and expose from their view definition type
• Package-level filter extraction — filter directives inside package bodies are collected alongside view-body filters
• Transitive port type hierarchy — port compatibility checks walk specialisation chains and detect common ancestors before flagging warnings
• Viewpoint satisfaction diagnostic — view-no-scope info hint when a view usage has no expose or filter
• view-showcase.sysml sample — 17 view usages demonstrating all supported view/filter/render scenarios
• View filter contract tests — 45 new extension tests covering boolean expressions, metaclass resolution, metadata matching, subview tracking, and render mappings
• LSP test coverage — 13 new tests for transitive type hierarchy, viewpoint diagnostics, and symbol table view/filter/expose/rendering extraction

Fixed

• Multi-filter AND semantics — multiple filter directives now correctly combine with AND; previously the fast path used set union (OR)

Removed

• Dead code: unused _lastUpdateTime field and unreferenced findElementInParent() method

Release 0.33.0

SysML v2.0 Extension v0.33.0

Added

• LSP model caching — LspModelProvider now caches results by URI, avoiding redundant LSP requests when multiple consumers (model explorer, visualization, feature inspector, dashboard) query the same file
• Consolidated file-change notifications — save, edit, and file-system-watcher events are debounced into a single 300ms notification per URI, eliminating up to 3 redundant panel refreshes per save
• Parallel workspace loading — model explorer loads files in chunks of 4 concurrently instead of sequentially, improving workspace load times
• Dependabot configuration — automated dependency updates for npm and GitHub Actions with grouped minor/patch PRs
• npm audit in CI — lint job now runs npm audit --audit-level=high to catch known vulnerabilities
• LSP dependency management scripts — lsp:local, lsp:npm, and lsp:which scripts for switching between local and npm LSP versions

Changed

• Updated sysml-v2-lsp dependency from 0.12.0 to 0.13.0 — batch parsing bug fixes (DFA pre-seed retry, error listener ordering, SLL error collection)
• Upgraded typescript from 5.x to 6.0.2
• Upgraded eslint from 9.x to 10.2.0 and @eslint/js to 10.0.1
• Upgraded @types/node from 24.x to 25.6.0 and @types/vscode to 1.116.0
• Upgraded cytoscape to 3.33.2 and @vscode/vsce to 3.9.0
• Unit tests now run compiled .js output instead of using ts-node, fixing compatibility with Node 22+ ESM resolution
• Release workflow restricted to main branch and version tags only

Fixed

• Unit test failures on Node 22 — replaced CJS Module._resolveFilename vscode mock hook with a plain .cjs require hook that works with Node 22's ESM module resolution
• Release workflow running on non-main branches — added branch guard (main and v* tags only)
• CI YAML syntax errors — converted inline node -e scripts to YAML block scalars to avoid nested quote issues

Removed

• Deprecated downlevelIteration option from tsconfig.json (unnecessary with ES2022 target, deprecated in TypeScript 6)

Release 0.28.0

SysML v2.0 Extension v0.28.0

Added

• Requirement satisfy/verify diagnostics — warnings for unsatisfied and unverified requirements
• Cross-file go-to-definition — Ctrl+Click navigates to definitions in other workspace files and standard library packages
• Library unit resolution — SI and USCustomary units (kg, foot, knot, etc.) resolve in constraint expressions

Changed

• Updated sysml-v2-lsp dependency from 0.8.0 to 0.9.0
• CI/release workflows updated to Node.js 22 LTS; GitHub Release action bumped to v4
• Sequence diagram spacing adapts to label width; long labels truncated with tooltip

Fixed

• False-positive syntax errors suppressed — arithmetic operators, collection expressions (->select, ->collect), and unit expressions (W/m^2) no longer flagged inside block bodies
• Concatenated type names
• Keyword validator — collect, xor, null, implies no longer flagged as misspelled keywords

Release 0.27.0

SysML v2.0 Extension v0.27.0

Added

• Metadata visualization — metadata def and metadata elements now render as first-class structural nodes in diagram views
• Base type display on nodes — diagram nodes show specialization and typing relationships using SysML notation (:> for definitions, : for usages)
• Attribute values in diagram nodes — definition nodes display attribute values inline

Changed

• Updated sysml-v2-lsp dependency from 0.7.0 to 0.8.0
  • Fixed extractName() picking up prefix metadata annotation names instead of element names
  • Metadata annotations extracted and emitted in model DTOs

Fixed

• Metadata keyword text colour — metadata def and metadata keywords now render in purple (#D4A5FF) instead of falling through to the grey default

Release 0.25.0

SysML v2.0 Extension v0.25.0

Added

• Comprehensive test suite — new test files covering CodeLens, diagram buttons, editing features, MCP server, Model Explorer integration, performance and visualization panel (224 tests total, 176 unit + 48 integration)
• CI pipeline restructured — split into 3 parallel jobs: lint, unit-tests, and integration-tests (runs after lint + unit pass)
• Release pipeline test gate — test job must pass before the release job runs

Changed

• Updated sysml-v2-lsp dependency from 0.5.1 to 0.6.0
• Makefile: make test runs unit tests only; make test-integration runs the full Extension Host suite

Fixed

• end port validation false positive (#15) — parser erroneously rejected end port, end part, end item, and other end <keyword> syntax in interface/connection definitions; root cause was a stale DFA snapshot in the LSP server that didn't cover the new grammar paths
• DFA snapshot robustness — LSP parser now retries with a cleared DFA when pre-seeded states produce parse errors, preventing stale snapshots from causing silent failures
