- Add API support for SCTP port mapping
- Add canonical import path
- Add `REMOVE` and `ORPHANED` to TaskState
- Fix TLS from environment variables in client
- Introduce NewClientWithOpts func to build custom client easily
- Wrap response errors for container copy methodsto fix error detection using
`IsErrNotFound` and `IsErrNotImplemented` for `ContainerStatPath`,
`CopyFromContainer`, and `CopyToContainer` methods.
- Produce errors when empty ids are passed into inspect calls
