Release schedule

Neos releases follow Semantic Versioning, and the team strives for a regular Neos release every four months:

  • Three minor releases per year, with patch level releases as needed in between
  • Major releases happen yearly, assuming there will be breaking changes
  • Each release receives bug fixes for at least 1 year (extended by previous LTS) and security fixes for 1 additional year (at least 2 in total)
  • Each Long Term Support (LTS) version receives bug fixes for 2 years and security fixes for 1 additional year (3 in total)
