+### Bug Fixes
+
+- **Dotted form values:** Preserve literal emails, URLs, and version strings in form value lookups instead of treating them as missing state paths (#353)
+- **Numeric validation:** Reject partially numeric strings such as `"123abc"`, empty strings, and whitespace-only strings instead of accepting them as numbers (#389)
+- **Schema type inference:** Infer `s.any()` fields as `any`, matching `z.any()`, so validated specs remain assignable to `Spec` without casts (#390)
+
+### Documentation
+
+- Migrated the **docs site** to Geistdocs while preserving public URLs, page content, and anchors (#340)
+- Updated **native WebMCP discovery and search** with the Geistdocs MCP adapter (#363)
