Support information

untermStrich guarantees 18 months of support from the last major release or the end of development of a version. The following schedule, therefore, applies to the current and previous untermStrich versions:


  • End of support: No more support (written or by phone) will be provided for this version. There will be no bugfixes, nor will there be any adaptations to changed operating environments.
  • End of development: No new features will be implemented for the version from this point on. Bugfixes and hotline support will be implemented and delivered until the end of support. No adaptations to changed operating environments will be made.
  • Current version: New functionalities are implemented, support for new operating systems or Office products is guaranteed
  • Major version: Always up to the second digit (e.g. – so here 10.8.). New major versions mostly result from the changed operating environments, e.g. X → X.1, because of the operating systems’ latest PHP versions.
