The Qubes OS Project uses the [semantic versioning](https://semver.org/)
standard. Version numbers are written as `<major>.<minor>.<patch>`. When
`<patch>` is zero, it is often omitted as a matter of convention, e.g., `4.1`.

## Release schedule
There is no specific schedule for releases other that more general
roadmap. When time comes, Supreme Committee declares feature freeze and tags
`-rc1` and releases ISO image. From this time on, no new features are accepted.
Also a strict time schedule kicks in.

When time comes, Supreme Committee declares feature freeze and tags `-rc1` and

strict time schedule kicks in.
Each release candidate period is as follows. For the first two weeks we accept
and assign bug reports to be fixed before next release candidate. For the next
two weeks we generally focus on fixing assigned bug reports, so issues discovered
during this time may be postponed until later RC. Finally after that there is
one week of current-testing freeze, during which time no new packages are
released, in hope that they will be installed by wider user base and tested.

The next RC is released five weeks after the former. All packets are published
in `current` repository and the cycle starts over. There should be no less than
1 and no more than 3 release candidates before final release.

should be another RC. If, based on remaining issues, the Committee decides to
release final, then the Committee agrees upon the release date, which should be
no later than a week after.
