Key points
- Four releases a year on known dates (within reason, weekends, blockers, etc.).
- Everything merged to master at all times is intended and ready to be included in the next scheduled release. No or minimal cherry-picking to release branches. Keep master releasable.
- Each release has a fixed and well known feature-freeze date. Features may be targetted targeted for releases, but no promises are made of features being included unless they have been merged to master by that date.
- Everything merged to master at all times prior to feature freeze is intended and ready to be included in the next scheduled release. Keep master releasable!
- Merging earlier rather than later in the merge window is to be encouraged!
- After the feature freeze date only , fixes intended for the release should be merged to master delivery until the next feature window opens. Aside from any release-specific commits, the release The delivery branch will be kept in sync with mastermerged to both master and release branches on a weekly schedule.
- All fixes merged to master delivery after the feature-freeze date should be made assessed and reviewed in accordance with the Bug Priority Guidelines
- One release a year is designated a long-term / extended support version -
- Only this release has a full NetCAT process, and subsequently a much shorter (month less) merge window to accommodate it (and because the emphasis for this release should be on fully stabilising features added in the previous 3 releases).
- For 9 months of the year that means that people have a choice of two downloads (need to consider how to describe that, and what if any infrastructure concerns that brings?). NetBeans 11.0 remains available until April 2020.
- Minimal serious bug fixes might be backported to the LTS release and pushed via UC, taking into account the Bug Priority Guidelines (critical or blocker affecting significant users?) These should be done on the relevant release branch.
- Users needing features should be encouraged on to the faster release train, and help test those features before next LTS.
- Major version number is incremented for LTS. So NetBeans 12.0 would be in April 2020. Perhaps counter-intuitively the major version number would be increased for the versions with least new features. (Consider NetBeans 11.1 equivalent to NetBeans 11 feature update 1?)
History
In 2019 there was a decision to move towards a time-based, quarterly release schedule for Apache NetBeans releases. This started from Apache NetBeans 11.1, and retrospectively designated Apache NetBeans 11.0 as an LTS release.
At the end of 2019 the schedule was shifted back by one month, to avoid the end of year period. At the end of 2020, master freezing was replaced by a move to a delivery and release branch mechanism.
In early 2021, a decision was made to review the process and requirements for LTS releases, and in October 2021 a decision was made to concentrate solely on quarterly releases, changing the numbering scheme accordingly. No further LTS release will be made.
