This information is out of date and being updated. The new development strategy is announced here, please read the full text of the development strategy for more information. This notice was modified on 30 Apr 2014.
Joomla! is developed using a fixed release cycle. Every six months, the Joomla! Project releases a new minor or major version of Joomla!. Joomla!'s version format is:
Each version of Joomla! is supported by the Joomla! Project for a limited amount of time. There are two classifications for support: short term support (STS) and long term support (LTS). Every fourth release will be assigned long term support.
Please note that both STS and LTS releases, once they have reached the GA (General Availability) status, are fully functional and ready to be used in production environment. The disadvantage of using STS releases is that you will need to update your installation of Joomla! every six months, while the advantage is that you will have access to new features and extensions earlier.
Generally, the first STS release after an LTS release indicates the beginning of a new major release cycle. This STS release introduces fundamentally new features and changes that break compatibility with the previous LTS. Two more STS releases follow (usually compatible with the first STS release), and the release cycle is finished by the release of an LTS release which finalizes the work of the three STS releases. The four releases in one cycle will usually be numbered [major].0,[major].1 and [major].2 (STS) and [major].5 (LTS). For example, the STS release 3.0 will include breaking changes from 2.5, and 3.5 will include matured versions of the changes in 3.0, 3.1 and 3.2.
Usually, there will be a migration path (an officially supported way of migrating to the next version) between two LTS releases (from [major].5 to [next major].5) and between an LTS release and the STS releases in its major release cycle (from [major].2 to [major].5, for example), but not necessarily to the following STS releases (from [major].5 to [next major].0). In the case of 1.5 to 2.5 (LTS to LTS), for example, there is a migration path. Note that in the case of 2.5 to 3.0 (LTS to STS), there is also built-in migration path, since the changes aren't too incompatible.
For more information, see the official Development Strategy.
"Also, for the six months after Joomla! 3.3 is released, the Joomla! Project will be releasing Security Updates for both 3.2 AND 3.3 (as well as 2.5) so any new vulnerabilities can be promptly patched with a one-click update without the need to immediately update to Joomla! 3.3, giving you time to request your hosting provider to update their PHP version."
