0.22.0 / 2019-11-29

• Default watch timeouts changed to 300s everywhere

• However, if your Reflector relies on frequent polling you can set timeout or hide the poll() in a different context so it doesn't block your main work
• Internal RwLock changed to a futures::Mutex for soundness / proper non-blocking - #94
• blocking Reflector::read() renamed to async Reflector::state()
• Expose metadata.creation_timestamp and .deletion_timestamp (behind openapi flag) - #93
