Versioning (Release number info) August 08, 2008 / Updated: October 26, 2026

Please note the following definitions on what each of the digits in our release numbering signifies.

Since 1.4.7 we generally try to follow semantic versioning:

• patch release with small version jumps like 1.6.7 to 1.6.8: This should generally be compatible with the official release containing bugfixes only. (we previously may have referred to this as "support build")
• minor release with greater version jumps like 1.6.8 to 1.7. This should also generally be compatible with the official release but it cannot always fully be guaranteed (also previously often called "support build")
• major release with major changes and great version jumps like from 1.7. to 2.0: This may not be compatible with the official release introducing breaking changes. (we previously may have referred to this as "development build")

Version numbers characters appended to the version like 1.7a, 1.7b or 1.7RC may suggest the development progress (alpha, beta, Release Candidate) but are not a fixed status.

Prior 1.4.7:

• Change in the first digit of the release represents a major change (e.g. 1.x to 2.x)
• Change in the second digit represents a major feature release (e.g. 1.3 to 1.4)
• Change in the third digit represents a minor feature release with new features and bugfixes  (e.g. 1.4.3 to 1.4.4)
• Change in the fourth digit represents a support release with only bugfixes (e.g. 1.4.4.1)

In the case of support releases we expect no compatibility issues with running sites. For all other releases you should review the release announcement to get an idea of possible incompatibilities with third party themes and plugins.
