Release Summary

Bugfix release with documentation warnings about using certain functionality when connecting to the Docker daemon with TCP TLS.

Bugfixes

• socket_handler module utils - make sure this fully works when Docker SDK for Python is not available (https://github.com/ansible-collections/community.docker/pull/620).
• vendored Docker SDK for Python code - fix for errors on pipe close in Windows (https://github.com/ansible-collections/community.docker/pull/619).
• vendored Docker SDK for Python code - respect timeouts on Windows named pipes (https://github.com/ansible-collections/community.docker/pull/619).
• vendored Docker SDK for Python code - use poll() instead of select() except on Windows (https://github.com/ansible-collections/community.docker/pull/619).

Known Issues

• docker_api connection plugin - does not work with TCP TLS sockets! This is caused by the inability to send an close_notify TLS alert without closing the connection with Python's SSLSocket (https://github.com/ansible-collections/community.docker/issues/605, https://github.com/ansible-collections/community.docker/pull/621).
• docker_container_exec - does not work with TCP TLS sockets when the stdin option is used! This is caused by the inability to send an close_notify TLS alert without closing the connection with Python's SSLSocket (https://github.com/ansible-collections/community.docker/issues/605, https://github.com/ansible-collections/community.docker/pull/621).
