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

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 0.26.0

SysML v2.0 Extension v0.26.0

Added

• Model Explorer package context menu action: View Model Dashboard
• Model Dashboard now support workspaces

Changed

• LSP updated to 0.7.0
  • Improved semantic validation
  • New quick fix actions
  • Model Complexity Index calculation tweaks
  • Model Dashboard workspace targeting UI: file/semantic mode toggle with filtered target dropdown
  • Updated to OMG 2026-02 - SysML v2 Release

Fixed

• Visualizer filter reliability across diagram data sources (including non-standard element collections)
• State transition rendering for qualified names and selected-machine transition mapping
• Webview disposal race conditions in visualizer updates/postMessage paths
• Model Dashboard auto-refresh on file changes while open

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

Release 0.22.0

SysML v2.0 Extension v0.22.0

Added

• Feature Inspector panel (src/panels/featureInspectorPanel.ts) — cursor-tracking webview showing resolved type information, specialization breadcrumbs, feature tables with direction/multiplicity/modifier badges, clickable type drill-down, and navigation history with back button
• Feature Explorer tree view (src/explorer/featureExplorerProvider.ts) — master-detail sidebar showing resolved type info, specialization chains, and feature groups (parts, ports, attributes, etc.) for the selected definition
• Model Complexity Index (MCI) — status bar indicator (0–100 score) with hotspot detection for complex elements, documentation coverage, coupling analysis, and textual rating
• Model Explorer workspace modes — toggle between By File and Semantic Model views; workspace-wide model loaded automatically for .code-workspace projects; active document auto-revealed in tree
• Diagnostic-reactive status bar — live error/warning counts with colour-coded icons ($(error) / $(warning) / $(check)); click to open the Problems panel
• LSP server health in status bar tooltip — uptime, heap/RSS memory usage, and cache statistics (documents, symbol tables, semantic tokens)
• SysML: Show Type Hierarchy command — surfaces VS Code's built-in type hierarchy view for SysML definitions
• SysML: Show Call Hierarchy command — surfaces VS Code's built-in call hierarchy view for action/state invocations
• SysML: Toggle View: By File / Semantic Model command — switch Model Explorer between file-based and semantic views
• Workspace pre-parsing settings — sysml.workspace.preloadOnOpen (always / workspaceOnly / never) and sysml.workspace.excludePatterns (glob array)
• Camera Example multi-file sample (samples/Camera Example/) — .code-workspace with 8 SysML files covering General View, Interconnection View, Activity, Sequence, State, and Use Case diagrams
• Animated parse progress indicator — status bar animation showing parse stages (assembling model, building blocks, linking elements) with real-time progress feedback

Changed

• SysML: Clear Parse Cache enhanced — now flushes server caches (documents, symbol tables, semantic token sets) with reported counts, then re-parses the active file immediately
• Model Dashboard updated with Model Complexity Index display and build timing metrics
• ESLint configuration modernised — flat config format with browser globals for webview JS, Node globals for scripts, vendor files ignored, type-checked TypeScript linting

Fixed

• ESLint errors in browser JS — added proper environment globals for media/game/, media/webview/, and scripts/ files; ignored third-party vendor bundles and .venv directory

Release 0.21.0

SysML v2.0 Extension v0.21.0

Added

• LSP model provider (src/providers/lspModelProvider.ts) — sends sysml/model requests to the language server for structured model data
• Model type definitions (src/providers/sysmlModelTypes.ts) — shared TypeScript types for elements, relationships, and model statistics
• Model Dashboard panel (src/panels/modelDashboardPanel.ts) — webview dashboard showing model statistics and build timing
• Go-to-Definition for library imports — navigate to standard library definitions from import statements
• modelBuildTimeMs timing metric — real ANTLR parse time from the LSP server, reported consistently across status bar, dashboard, and output log

Changed

• Architecture: complete migration to LSP-only model — visualization panel and model explorer now use sysml/model LSP requests instead of the in-extension ANTLR parser; the extension no longer bundles any parser, resolver, or library code
• Visualization panel refactored (src/visualization/visualizationPanel.ts) — rebuilt to consume LSP model data directly
• Model Explorer refactored (src/explorer/modelExplorerProvider.ts) — uses LSP model provider instead of in-extension parser
• Extension activation refactored (src/extension.ts) — streamlined for LSP-only architecture

Fixed

• LSP cold-start race condition — model explorer and visualization now wait for the server to be ready
• Filename encoding in logs — spaces in filenames are properly handled

Removed

• In-extension ANTLR parser (src/parser/) — antlrSysMLParser.ts, sysmlParser.ts, parserWorker.ts, parserWorkerHost.ts, libraryIndexer.ts, vscodeMock.ts, and generated/ directory
• Semantic resolver (src/resolver/) — resolver.ts, diagnostics.ts, types.ts, index.ts
• Library service (src/library/) — service.ts, cacheManager.ts, compiler.ts, types.ts, index.ts
• Grammar files (grammar/) — SysMLv2Lexer.g4, SysMLv2Parser.g4
• sysml.library/ directory — standard library files now bundled in the LSP server
• antlr4 runtime dependency

Release 0.20.0

SysML v2.0 Extension v0.20.0

Fixed

• Comprehensive keyword validator fix: eliminated ~100 false-positive "Unexpected identifier where a SysML keyword was expected" diagnostics by adding missing tokens to NAME_PRECEDING_KEYWORDS — covers KerML elements, annotations, control nodes, reference-preceding keywords, succession/flow tokens, relationship keywords, modifiers, visibility keywords, and punctuation (e.g. attribute redefines, <'short-name'> identifier, exhibit, perform, include, etc.)

Changed

• Updated sysml-v2-lsp dependency from 0.1.6 to 0.1.7
