Release policy

The releases done by KAMAILIO (OpenSER) project are guided by the following policies.

Versioning

Each Kamailio (OpenSER) version is composed of 3 numbers, separated by dots: X.Y.Z

  • X and Y are used to identify the major releases
  • Z is used to identify the minor releases

Incrementing the numbers in version string:

  • X is changed when radical changes are included, like new internal architecture
  • Y is changed for each major release
  • Z is changed for each minor release

Major release

A major release includes new features in core or modules and may not preserve configuration file or database structure compatibility with previous major release.

  • 6 to 8 months based releasing
  • 4-6 months development
  • approximately 2 months extensive testing
  • these releases are derived from the trunk version
  • the version of a major release ends in 0 (Z=0): X.Y.0

Minor release

A minor release includes bug fixes and documentation updates done for a major release. It preserves configuration file and database structure compatibility.

  • 1 to 3 months after a major release
  • shorter testing period
  • one ore more minor releases depending on the demand
  • this releases are derived from the stable branch
  • the version of a minor release keeps same X and Y from the major release <span class=“plainlinks”>[http://www.shoppharmacycounter.com/ <span style=“color:black;font-weight:normal; text-decoration:none!important; background:none!important; text-decoration:none;”>weight loss pills</span>] and changes Z.
