In the current release model, versions are released like the following
|
|
(the table shows the year/quarter of the planned GA release):
|
|
|
|
Q1 Q2 Q3 Q4
|
|
2022 10.7 10.8 10.9 10.10
|
|
2023 10.11-LTS 11.0 11.1 11.2
|
|
2024 11.3 11.4-LTS 11.5 11.6
|
|
2025 11.7 11.8-LTS 12.0 12.1
|
|
2026 12.2 12.3-LTS 13.0 13.1
|
|
2027 13.2 13.3-LTS 14.0 14.1
|
|
2028 14.2 14.3-LTS 15.0 15.1
|
|
2029 15.2 15.3-LTS 16.0 16.1
|
|
...
|
|
|
|
A deprecated feature can be removed only when all releases when it's
|
|
not deprecated have reached EOL. For example, if something was
|
|
deprecated in 11.3, then 10.11 (where it wasn't deprecated) will reach
|
|
EOL in Q1 2028 (standard 5 years LTS life time). Meaning, the feature can
|
|
be removed in 13.4.
|
|
|
|
When the release model changes, the table above and templates below
|
|
have to be updated.
