 ### Fixes
 
@@ -25,6 +28,15 @@
 - Bump PWA precache limit for canvaskit-webgpu

 - Fix .fig import crash on alias variables without a GUID
+- Fix `save_file` crash on vectors with missing tangent control points — default to straight segments
+- Validate `create_vector` path JSON upfront with clear error messages for malformed input
+- Fix MCP/AI tools rejecting string-encoded numeric arguments from MCP clients (`"42"` → `42`)
+- Fix "Create Instance" context menu item always grayed out — inverted disabled flag
+- Show "Create Instance" instead of "Create Component" in context menu when a component is selected
+- Fix headless layout: use stored .fig dimensions instead of rough text size estimates (26K → 11K mismatches on material3.fig)
+- Fix `--help` output with huge vertical gaps between commands — remove inline examples from query description
+- Fix `openpencil-mcp` npm package missing `dist/stdio.js` — explicitly list entry points in tsconfig
+- Show toast when MCP server fails to start instead of silently swallowing the error
 - Fix external links in AI panel blocked by Tauri ACL — use opener plugin instead of shell
