As of Elgg 2.0, each minor release receives bug and security fixes only until the next minor release.
Within each major version, the last minor release is designated for long term support (“LTS”) and will receive bug fixes until 1 year after the release of the next major version and security fixes until the 2nd following major version release.
E.g. 2.3 is the last minor release within 2.x. It will receive bug fixes until 1 year aftr 3.0 is released and security fixes until 4.0 is released.
When bugs are found, a good faith effort will be made to patch the LTS release, but not all fixes will be back-ported. E.g. some fixes may depend on new APIs, break backwards compatibility, or require significant refactoring.
If a fix risks stability of the LTS branch, it will not be included.
Below is a table outlining the specifics for each release (future dates are tentative):
