Release schedule policy
For the benefit of its users, Helm defines and announces release dates in advance. This document describes the policy governing Helm's release schedule.
Release calendar
A public calendar showing the upcoming Helm releases can be found here.
Semantic versioning
Helm versions are expressed as x.y.z, where x is the major version, y is
the minor version, and z is the patch version, following
Semantic
Versioning terminology.
Patch releases
Patch releases provide users with bug fixes and security fixes. They do not contain new features.
A new patch release relating to the latest minor/major release will normally be done once a month on the second Wednesday of each month.
A patch release to fix a high priority regression or security issue can be done whenever needed.
A patch release will be cancelled for any of the following reasons:
- if there is no new content since the previous release
- if the patch release date falls within one week before the first release candidate (RC1) of an upcoming minor release
- if the patch release date falls within four weeks following a minor release
Minor releases
Minor releases contain security and bug fixes as well as new features. They are backwards compatible with respect to the API and the CLI usage.
To align with Kubernetes releases, a minor helm release will be done every 4 months (3 releases a year).
Extra minor releases can be done if needed but will not affect the timeline of an announced future release, unless the announced release is less than 7 days away.
At the same time as a release is published, the date of the next minor release will be announced and posted to Helm's main web page.
Major releases
Major releases contain breaking changes. Such releases are rare but are sometimes necessary to allow helm to continue to evolve in important new directions.
Major releases can be difficult to plan. With that in mind, a final release date will only be chosen and announced once the first beta version of such a release is available.
