Changes since the last release:
- Tasks can now carry a retry policy that decides whether a failure is worth retrying.
- Heartbeat writes are batched, which cut metadata database load by about a third in testing.
- Fixed a crash when two tasks in one Dag file shared a task id.
- Dropped support for Python 3.9.
