Changelog

Sourced from kube's changelog.

0.23.0 / 2019-12-31

• Bump tokio and reqwest to 0.2 and 0.10
• Fix bug in log fetcher - #107
• Temporarily allow invalid certs when testing on macosx - #105

0.22.2 / 2019-12-04

• Allow sharing Reflectors between threads - #97
• Fix Reflector pararall lock issue (poll no longer blocks state)

0.22.1 / 2019-11-30

• Improve Reflector reset algorithm (clear history less)

0.22.0 / 2019-11-29

• Default watch timeouts changed to 300s everywhere
• This increases efficiency of Informers and Reflectors by keeping the connection open longer.
• 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

0.21.0 / 2019-11-29

• All watch calls returns a stream of WatchEvent - #92
• Informer::poll now returns a stream - #92

0.20.1 / 2019-11-21

• ObjectList now implements Iterator - #91
• openapi feature no longer accidentally hardcoded to v1.15 feature - #90

0.19.0 / 2019-11-15

• kube::Error is now a proper error enum and not a Fail impl (thiserror)
• soft-tokio dependency removed for futures-timer
• gzip re-introduced

0.18.1 / 2019-11-11

• Fix unpinned gzip dependency breakage - #87

0.18.0 / 2019-11-07

• api converted to use async/await with 1.39.0 (primitively)
• hyper upgraded to 0.10-alpha
• synchronous sleep replaced with tokio timer
• Log trait removed in favour of internal marker trait

... (truncated)
