# Releases
|
||
|
|
|
||
|
|
The release process hopes to encourage early, consistent consensus-building during project development.
|
||
|
|
The mechanisms used are regular community communication on the mailing list about progress, scheduled meetings for issue resolution and release triage, and regularly paced and communicated releases.
|
||
|
|
Releases are proposed and adopted or rejected using the usual [project governance](GOVERNANCE.md) rules and procedures.
|
||
|
|
|
||
|
|
An anti-pattern that we want to avoid is heavy development or discussions "late cycle" around major releases.
|
||
|
|
We want to build a community that is involved and communicates consistently through all releases instead of relying on "silent periods" as a judge of stability.
|
||
|
|
|
||
|
|
## Parallel releases
|
||
|
|
|
||
|
|
A single project MAY consider several motions to release in parallel.
|
||
|
|
However each motion to release after the initial 0.1.0 MUST be based on a previous release that has already landed.
|
||
|
|
|
||
|
|
For example, runtime-spec maintainers may propose a v1.0.0-rc2 on the 1st of the month and a v0.9.1 bugfix on the 2nd of the month.
|
||
|
|
They may not propose a v1.0.0-rc3 until the v1.0.0-rc2 is accepted (on the 7th if the vote initiated on the 1st passes).
|
||
|
|
|
||
|
|
## Specifications
|
||
|
|
|
||
|
|
The OCI maintains three categories of projects: specifications, applications, and conformance-testing tools.
|
||
|
|
However, specification releases have special restrictions in the [OCI charter][charter]:
|
||
|
|
|
||
|
|
* They are the target of backwards compatibility (§7.g), and
|
||
|
|
* They are subject to the OFWa patent grant (§8.d and e).
|
||
|
|
|
||
|
|
To avoid unfortunate side effects (onerous backwards compatibity requirements or Member resignations), the following additional procedures apply to specification releases:
|
||
|
|
|
||
|
|
### Planning a release
|
||
|
|
|
||
|
|
Every OCI specification project SHOULD hold meetings that involve maintainers reviewing pull requests, debating outstanding issues, and planning releases.
|
||
|
|
This meeting MUST be advertised on the project README and MAY happen on a phone call, video conference, or on IRC.
|
||
|
|
Maintainers MUST send updates to the dev@opencontainers.org with results of these meetings.
|
||
|
|
|
||
|
|
Before the specification reaches v1.0.0, the meetings SHOULD be weekly.
|
||
|
|
Once a specification has reached v1.0.0, the maintainers may alter the cadence, but a meeting MUST be held within four weeks of the previous meeting.
|
||
|
|
|
||
|
|
The release plans, corresponding milestones and estimated due dates MUST be published on GitHub (e.g. https://github.com/opencontainers/runtime-spec/milestones).
|
||
|
|
GitHub milestones and issues are only used for community organization and all releases MUST follow the [project governance](GOVERNANCE.md) rules and procedures.
|
||
|
|
|
||
|
|
### Timelines
|
||
|
|
|
||
|
|
Specifications have a variety of different timelines in their lifecycle.
|
||
|
|
|
||
|
|
* Pre-v1.0.0 specifications SHOULD release on a monthly cadence to garner feedback.
|
||
|
|
* Major specification releases MUST release at least three release candidates spaced a minimum of one week apart.
|
||
|
|
This means a major release like a v1.0.0 or v2.0.0 release will take 1 month at minimum: one week for rc1, one week for rc2, one week for rc3, and one week for the major release itself.
|
||
|
|
Maintainers SHOULD strive to make zero breaking changes during this cycle of release candidates and SHOULD restart the three-candidate count when a breaking change is introduced.
|
||
|
|
For example if a breaking change is introduced in v1.0.0-rc2 then the series would end with v1.0.0-rc4 and v1.0.0.
|
||
|
|
- Minor and patch releases SHOULD be made on an as-needed basis.
