Automated build from main branch (commit: 833f7c5)

0.3.51 - 2026-03-04

Release Notes

Changed

• Bump stdlib to 0.5.11

Added

• Added typed part metadata with builtin.Part(...) and Component(part=...), including JSON netlist serialization and list[Part] support for properties["alternatives"].

0.3.49 - 2026-03-02

Release Notes

Changed

• Replace [assets] with [[workspace.kicad_library]] for built-in resolution of KiCad symbol, footprint, and 3D model repositories.
• Embed referenced 3D models directly into .kicad_pcb layout files, eliminating the need for external 3D model files at layout time.

0.3.48 - 2026-02-28

Release Notes

Added

• pcb simulate: run SPICE simulations directly via ngspice with inline set_sim_setup(), --netlist/-o - output, workspace discovery, and LSP diagnostics on save. Errors on components missing a SpiceModel to prevent incomplete netlists.
• Support net names in f-strings for SPICE simulation setup (e.g. f"V1 {VIN} {GND} AC 1"), including dot-notation for interface nets ({POWER.vcc}).

Fixed

• Normalize net and component symbol source paths to package://..., so emitted schematic/netlist symbol_path values no longer leak absolute cache paths.

0.3.46 - 2026-02-26

Release Notes

Changed

• Use zstd level 17 (was 15) when embedding STEP 3D models into KiCad footprints.
• Path(..., allow_not_exist=True) no longer emits missing-path warnings.
• pcb search component add now prefers symbol datasheets, using fallback URL scan only when needed.
• pcb search add-component now rewrites symbol Manufacturer_Part_Number/Manufacturer_Name metadata before generating .zen.

Fixed

• Normalize netlist package_roots cache paths to <workspace>/.pcb/cache for unvendored remote dependencies (including stdlib).
• MCP resolve_datasheet now avoids top-level JSON Schema combinators in inputSchema, fixing strict MCP clients (e.g., Claude Code) that reject oneOf at schema root.

0.3.45 - 2026-02-25

Release Notes

Added

• Added MCP tool resolve_datasheet to produce cached datasheet.md + images/ from datasheet_url, pdf_path, or kicad_sym_path.
• Added LSP request pcb/resolveDatasheet, sharing the same resolve flow as the MCP tool.

Fixed

• Standalone .zen files with inline manifests now map Board(..., layout_path=...) to package://workspace/..., avoiding absolute-path leakage.
• Stackup sync now emits dielectric (type ...) once per grouped layer (not per addsublayer), preventing spurious layout.sync drift.

0.3.44 - 2026-02-20

Release Notes

Added

• Component() now infers missing footprint from symbol Footprint (<stem> or KiCad <lib>:<fp>), reducing duplicated footprint data over .kicad_sym.

Changed

• MCP external tool discovery now prefers mcp --code-mode=false (raw tools) and falls back to mcp only when needed, avoiding nested code-mode wrappers for compatible pcb-* backends.

Fixed

• Reduced layout.sync false positives in publish/check flows by normalizing .kicad_pro newline writes and ignoring trailing whitespace-only drift when comparing synced layout files.
• Simplified dependency fetch/index concurrency paths and reuse a shared cache index during resolve/fetch phases to reduce open-file pressure on macOS.
• Auto-deps is now conservative and online-only: it adds remote deps only after successful materialization, skips imports already covered by existing dependencies/assets, and no longer infers missing deps from pcb.sum.
• Branch-based dependencies now require commit pinning for reproducibility: online resolve/update pins branch deps to rev, while --locked/--offline reject branch-only declarations.
• Fixed dotted pin-name handling by resolving port owners with longest-prefix component matching in netlist/layout/publish flows.

0.3.42 - 2026-02-13

Release Notes

Changed

• config() physical-value coercion now accepts numeric scalars (int/float) in addition to strings, matching constructor behavior.
• config() now enforces required module inputs: optional=False emits an error diagnostic even when default is set; omitted optional infers from default.
• Bump stdlib to 0.5.8

Fixed

• Fix package:// resolution for workspace and versioned dependencies, preventing absolute path leakage from File().
