 # Changelog
 
+## 2026-02-07 - 1.13.0 - feat(docker)
+add Docker context detection, rootless support, and context-aware buildx registry handling
+
+- Introduce DockerContext class to detect current Docker context and rootless mode and to log warnings and context info
+- Add IDockerContextInfo interface and a new context option on build/config to pass explicit Docker context
+- Propagate --context CLI flag into TsDockerManager.prepare so CLI commands can set an explicit Docker context
+- Make buildx builder name context-aware (tsdocker-builder-<sanitized-context>) and log builder name/platforms
+- Pass isRootless into local registry startup and build pipeline; emit rootless-specific warnings and registry reachability hint
+
 ## 2026-02-06 - 1.12.0 - feat(docker)
 add detailed logging for buildx, build commands, local registry, and local dependency info
