Versions and changes
All published releases with version number, release date and end of support. What has changed in each release is documented in the change history of the documentation — in German and English.
Since the switch to MSI-based installation, the version format is Year.HalfYear.Day.Revision — 2026.2.249.0 therefore stands for the year 2026, the second half of the year and the 249th calendar day. Older releases still carry the 4.1.8.x scheme. The numbering has changed, not the product line.
