If you are using a released version of Kubernetes, you should refer to the docs that go with that version.
The latest release of this document can be found [here](http://releases.k8s.io/release-1.2/docs/devel/issues.md).Documentation for other releases can be found at releases.k8s.io.
A quick overview of how we will review and prioritize incoming issues at https://github.com/kubernetes/kubernetes/issues
We use GitHub issue labels for prioritization. The absence of a priority label means the bug has not been reviewed and prioritized yet.
We try to apply these priority labels consistently across the entire project, but if you notice an issue that you believe to be misprioritized, please do let us know and we will evaluate your counter-proposal.
- priority/P0: Must be actively worked on as someone's top priority right now. Stuff is burning. If it's not being actively worked on, someone is expected to drop what they're doing immediately to work on it. TL's of teams are responsible for making sure that all P0's in their area are being actively worked on. Examples include user-visible bugs in core features, broken builds or tests and critical security issues.
- priority/P1: Must be staffed and worked on either currently, or very soon, ideally in time for the next release.
- priority/P2: There appears to be general agreement that this would be good to have, but we don't have anyone available to work on it right now or in the immediate future. Community contributions would be most welcome in the mean time (although it might take a while to get them reviewed if reviewers are fully occupied with higher priority issues, for example immediately before a release).
- priority/P3: Possibly useful, but not yet enough support to actually get it done. These are mostly place-holders for potentially good ideas, so that they don't get completely forgotten, and can be referenced/deduped every time they come up.
We additionally use milestones, based on minor version, for determining if a bug should be fixed for the next release. These milestones will be especially scrutinized as we get to the weeks just before a release. We can release a new version of Kubernetes once they are empty. We will have two milestones per minor release.
- vX.Y: The list of bugs that will be merged for that milestone once ready.
- vX.Y-candidate: The list of bug that we might merge for that milestone. A bug shouldn't be in this milestone for moe than a day or two towards the end of a milestone. It should be triaged either into vX.Y, or moved out of the release milestones.
The above priority scheme still applies, so P0 and P1 bugs are work we feel must get done before release, while P2 and P3 represent work we would merge into the release if it gets done, but we wouldn't block the release on it. A few days before release, we will probably move all P2 and P3 bugs out of that milestone tag in bulk.
