It really depends on when someone has time to work on it. Our releases
are time based, and will happen even when a bugfix/feature is not merged
or implemented. We can't give any guarantees about availability for
final patche (or backports).

The best you can do is help testing a potential fix, and work with the
developer(s) of that patch to improve and get it accepted in the master
branch. If developers do not have time to work on it, or progress is
slow, you can ask them if you can take it over from if you are
comfortable with writing the code.
