 # Changelog
 
+## 2026-02-07 - 1.16.0 - feat(core)
+Introduce per-invocation TsDockerSession and session-aware local registry and build orchestration; stream and parse buildx output for improved logging and visibility; detect Docker topology and add CI-safe cleanup; update README with multi-arch, parallel-build, caching, and local registry usage and new CLI flags.
+
+- Add TsDockerSession to allocate unique ports, container names and builder suffixes for concurrent runs (especially in CI).
+- Make local registry session-aware: start/stop/use registry container and persistent storage per session; retry on port conflicts.
+- Inject session into Dockerfile instances and TsDockerManager; use session.config.registryHost for tagging/pushing and test container naming.
+- Stream and parse buildx/docker build output via createBuildOutputHandler for clearer step/platform/CACHED/DONE logging and --progress=plain usage.
+- Detect Docker topology (socket-mount, dind, local) in DockerContext and expose it in context info.
+- Add manager.cleanup to remove CI-scoped buildx builders and ensure CLI calls cleanup after build/push/test.
+- Update interfaces to include topology and adjust many Dockerfile/manager methods to be session-aware.
+- Large README improvements: multi-arch flow, persistent local registry, parallel builds, caching, new CLI and clean flags, and examples for CI integration.
+
 ## 2026-02-07 - 1.15.1 - fix(registry)

+## Architecture: How tsdocker Works
+
+tsdocker uses a **local OCI registry** as the canonical store for all built images. This design solves fundamental problems with Docker's local daemon, which cannot hold multi-architecture manifest lists.

+### 🔑 Why a Local Registry?
+
+| Problem | Solution |
+|---------|----------|
+| `docker buildx --load` fails for multi-arch images | `buildx --push` to local registry works for any number of platforms |
+| `docker push` only pushes single-platform manifests | OCI API copy preserves full manifest lists (multi-arch) |
+| Images lost between build and push phases | Persistent storage at `.nogit/docker-registry/` survives restarts |
+| Redundant blob uploads on incremental pushes | HEAD checks skip blobs that already exist on the remote |

-Managing Docker workflows manually is tedious:
-- Remembering build order for dependent images
-- Pushing to multiple registries with different credentials
-- Setting up Buildx for multi-arch builds
-- Ensuring consistent test environments

-### ✨ The Solution
-
-tsdocker automates the entire workflow:
-- **One command** to build all images in dependency order
-- **One command** to push to all registries
-- **Automatic** Buildx setup for multi-platform builds
-- **Consistent** containerized test environments
