At times to be determined by the release working group, major versions will be frozen and transitioned to Long Term Support (LTS). After a determined period of time, versions in Long Term Support will be deep-frozen and transition to Maintenance.
Versions in Maintenance should not have any changes landed, except for:
- Critical bug fixes
- Critical security updates
- Important documentation updates
Unless a change is urgent, Maintenance releases are likely to be made with minimal frequency.
The v4 branch is currently in Active LTS and will receive bug fixes till 2021-07-01, after which
it will only receive critical fixes till its End of Life.
