Week Ending October 27, 2019

Developer News

Don’t forgt to register for the San Diego Contributor Summit.

The Kubernetes Community Meeting is changing formats and moving to a biweekly cadence in 2020.

The brand-new SIG-Usability has started having meetings and making plans. One thing they’re tackling for 1.17/1.18 is secure-by-default configuration. If you’re interested in usability and user experience, maybe join them.

Server-side apply is beta right now and WG Apply plans for more performance improvements in 1.17 before it goes GA. Unions and immutability are also WIP, but nobody is still working on server dry-run, so if you want that to be GA, maybe join WG Apply and lend a hand.

Release Schedule

Next Deadline: 1.17.beta0 released Oct 29th and branch

We are almost in burndown, with Code Freeze coming November 14th. We’re branching, and testgrid will be dropping 1.13 and adding 1.17 jobs. And all enhancements have been merged, so if you have a new one … submit it for 1.18.

No patch releases planned this week.
