 # 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
+
+- Log startup of local registry including a note about buildx dependency bridging
+- Log constructed build commands and indicate whether buildx or standard docker build is used (including platforms and --push/--load distinctions)
+- Emit build mode summary at start of build phase and report local base-image dependency mappings
+- Report when --no-cache is enabled and surface buildx setup readiness with configured platforms
+- Non-functional change: purely adds informational logging to improve observability during builds
+
+## 2026-02-06 - 1.11.0 - feat(docker)
+start temporary local registry for buildx dependency resolution and ensure buildx builder uses host network
+
+- Introduce a temporary local registry (localhost:5234) with start/stop helpers and push support to expose local images for buildx
+- Add Dockerfile.needsLocalRegistry to decide when a local registry is required (local base dependencies + multi-platform or platform option)
+- Push built images to the local registry and set localRegistryTag on Dockerfile instances for BuildKit build-context usage
+- Tag built images in the host daemon for dependent Dockerfiles to resolve local FROM references
+- Integrate registry lifecycle into Dockerfile.buildDockerfiles and TsDockerManager build flows (start before builds, stop after)
+- Ensure buildx builder is created with --driver-opt network=host and recreate existing builder if it lacks host network to allow registry access from build containers
+
+## 2026-02-06 - 1.10.0 - feat(classes.dockerfile)
+support using a local base image as a build context in buildx commands
+
+- Adds --build-context flag mapping base image to docker-image://<localTag> when localBaseImageDependent && localBaseDockerfile are set
+- Appends the build context flag to both single-platform and multi-platform docker buildx commands
+- Logs an info message indicating the local build context mapping
+
 ## 2026-02-06 - 1.9.0 - feat(build)
 add verbose build output, progress logging, and timing for builds/tests
