## v7 WIP
44

5+
- Tx.Pipeline now returns a non-transactional pipeline. Use Tx.TxPipeline for a transactional pipeline.
56
- WrapProcess is replaced with more convenient AddHook that has access to context.Context.
67
- WithContext now can not be used to create a shallow copy of the client.
78
- New methods ProcessContext, DoContext, and ExecContext.
