====== 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.
