 # Changelog
 
+## 2026-02-07 - 1.17.0 - feat(tsdocker)
+add Dockerfile filtering, optional skip-build flow, and fallback Docker config credential loading
+
+- Add TsDockerManager.filterDockerfiles(patterns) to filter discovered Dockerfiles by glob-style patterns and warn when no matches are found
+- Allow skipping image build with --no-build (argvArg.build === false): discover Dockerfiles and apply filters without performing build
+- Fallback to load Docker registry credentials from ~/.docker/config.json via RegistryCopy.getDockerConfigCredentials when env vars do not provide credentials
+- Import RegistryCopy and add info/warn logs when credentials are loaded or missing
+
 ## 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.
