Changelog

6.0.0

-----

Upgrade Notes
- Minimum supported Python version is 3.7+
- When installing with pip, the `docker[tls]` extra is deprecated and a no-op,
use `docker` for same functionality (TLS support is always available now)
- Native Python SSH client (used by default / `use_ssh_client=False`) will now
reject unknown host keys with `paramiko.ssh_exception.SSHException`
- Short IDs are now 12 characters instead of 10 characters (same as Docker CLI)

Features
- Python 3.10 support
- Automatically negotiate most secure TLS version
- Add `platform` (e.g. `linux/amd64`, `darwin/arm64`) to container create & run
- Add support for `GlobalJob` and `ReplicatedJobs` for Swarm
- Add `remove()` method on `Image`
- Add `force` param to `disable()` on `Plugin`

Bugfixes
- Fix install issues on Windows related to `pywin32`
- Do not accept unknown SSH host keys in native Python SSH mode
- Use 12 character short IDs for consistency with Docker CLI
- Ignore trailing whitespace in `.dockerignore` files
- Fix IPv6 host parsing when explicit port specified
- Fix `ProxyCommand` option for SSH connections
- Do not spawn extra subshell when launching external SSH client
- Improve exception semantics to preserve context
- Documentation improvements (formatting, examples, typos, missing params)

Miscellaneous
- Upgrade dependencies in `requirements.txt` to latest versions
- Remove extraneous transitive dependencies
- Eliminate usages of deprecated functions/methods
- Test suite reliability improvements
- GitHub Actions workflows for linting, unit tests, integration tests, and
publishing releases
