 ## [Unreleased]
 
+## [2.10.3] - 2026-03-13

+### Fixed
+- Native binary distribution — `.node` binaries were missing from the npm tarball, causing startup crashes on all platforms since v2.10.0
+- Native loader resolution chain: tries `@gsd-build/engine-{platform}` npm package first, then local dev build, with clear error messages listing supported platforms
+
+### Added
+- Per-platform optional dependency packages (`@gsd-build/engine-*`) for macOS (ARM64/x64), Linux (x64/ARM64), and Windows (x64)
+- Cross-platform native binary CI build and publish workflow
+- Version synchronization script for lock-step platform package releases
