Major versions (x.y) are maintained for 3 years. This is the active support: bugs fix, security hole, little improvements. This leads to the release of maintenance versions (minor versions x.y.z), every 1 to 3 months, depending on the criticality of bug fixes.
Then they are maintained one more year, only for security hole (security support).
Maintenance is extended if next major version is not ready after 3 years.
Major versions are noted x.y. Minor versions are noted x.y.z. So it does not follow exactly the semantic notation defined by Semver.
A new major version could have API breakage, but it is rare since Jelix 1.7.
Deprecated API are removed at each “ultra major” versions (like 1.0.0, 2.0.0…). But some deprecated API can be removed in some major versions when they are deprecated since many major versions.
This is why it is highly recommended to use the composer constraint ~ in the composer.json file of your project:
"require": {
"jelix/jelix-standard" : "~1.8.0"
}
Avoid to use the ^ constraint (for example ^1.8.0).
The latest available stable version is Jelix 1.8.10.
