On this page
Since 2022 the Nuclos version contains the release year. A version is structured as follows:
MAJOR.YEAR.COUNTER[.BUGFIX]
| Part | Meaning | Example |
|---|---|---|
MAJOR | Major version (rare) | 4 |
YEAR | Release year | 2026 |
COUNTER | Sequential, reset to 1 each year | 31 |
BUGFIX | Only for bugfix releases | 1 |
| Release type | Version | Git branch/tag |
|---|---|---|
| Minor release | 4.2026.1 | 4.2026.1 |
| Bugfix release | 4.2026.1.1 | 4.2026.1 |
Change in 2022
Changes compared to the old scheme (until 2021, e.g. 4.53.0): the year is also part of the minor segment, the counter restarts at 1 every year and the bugfix segment only appears for bugfix releases.
