1.3.0 (Extension 0.4.0)

PCB DRC Execution, CPL Export, Layer Stackup, Routing Status, PCB Components, Net Highlighting, Canvas Selection, and Library Search

• Active PCB DRC execution (easyeda_run_drc): execute native PCB design rule checks (eda.pcb_Drc.check) with optional verbose violation reporting.
• Pick-and-Place / CPL export (easyeda_export_cpl): generate component placement files (eda.pcb_ManufactureData.getPickAndPlaceFile) for SMT assembly workflows.
• PCB layer stackup (easyeda_get_pcb_layers): inspect active PCB layers, copper thicknesses, visibility, and layer types with case-insensitive copper filtering.
• PCB routing status (easyeda_get_routing_status): inspect routed vs. unrouted nets, track segments, vias, and airwire/ratline completion status on the active PCB.
• PCB component placement inspection (easyeda_list_pcb_components): list placed PCB footprints with coordinates, rotation, layer side (top/bottom), and designator filters.
• Interactive net highlighting (easyeda_highlight_net): highlight and dim specific nets directly on the active PCB canvas.
• Canvas selection inspection (easyeda_get_selection): inspect currently selected primitives on the active schematic or PCB canvas.
• Component library search (easyeda_search_library): search EasyEDA/LCSC component libraries (eda.lib_Device.search) by query and library UUID.

1.2.0 (Extension 0.2.0)

One-Command Client Setup, 1-Click Install Links, and Claude Desktop .mcpb Bundle

• Multi-client auto-installer (npx -y @vlabsoftware/easyeda-pro-mcp setup): automatically detects and configures Claude Desktop, Cursor, VS Code (servers schema), Antigravity, Windsurf, Claude Code (~/.claude.json), and Codex (~/.codex/config.toml) across macOS, Windows (cmd /c npx), and Linux while preserving existing MCP servers and comments.
• Bundled .eext extension in npm package (export-extension): packages build/dist/easyeda_mcp_bridge.eext inside @vlabsoftware/easyeda-pro-mcp so setup and export-extension extract the version-matched EasyEDA Pro extension directly to disk without cloning the repository.
• 1-click install badges & Claude Desktop .mcpb bundle (npm run package:mcpb): adds verified 1-click install links for Cursor and VS Code plus a standalone easyeda-pro-mcp.mcpb (manifest_version: "0.3") archive for Claude Desktop.
• Bridge environment variable hardening: safely falls back to 127.0.0.1:8765 when EASYEDA_MCP_WS_HOST or EASYEDA_MCP_WS_PORT are blank strings.

1.1.0 (Extension 0.2.0)

PCB DRC Design Rule Inspection and Editing (#14)

• Native PCB DRC rule reads (easyeda_get_drc_rules): inspect current PCB rules, saved configurations, netRules, netByNetRules, and regionRules, along with per-method runtime capability detection on eda.pcb_Drc.
• Immutable DRC edit previews (easyeda_prepare_drc_edit): stage changes without modifying the PCB and receive an editId, target PCB identity (projectUuid, documentUuid, tabId), before/after snapshot, and exact confirmation phrase.
• Confirmed DRC rule updates (easyeda_confirmed_action with action: "editDrcRules"):
  • createConfiguration: create a new named rule profile (allowOverwrite=false).
  • updateCurrentConfiguration: update the active PCB rule configuration.
  • replaceNetRules, replaceNetByNetRules, replaceRegionRules: replace rule tables on the active PCB.
• Stale-state & transport safety (easyeda_get_drc_edit_result): enforce exact confirmation (CONFIRM editDrcRules <editId>) at both the MCP server and extension boundaries, block execution if the PCB target, session, or underlying rules changed since preview, verify changes via full native readback, and query inconclusive/timed-out edits without replaying mutations.
• Release & CI hardening: unified runtime/package/manifest version checks (src/version.ts), end-to-end stdio + WebSocket DRC smoke test (npm run test:smoke:drc), and DRC Rule Editing documentation.
