Hi all,
A recent thread [1] had several topics of discussion come up about
proposed changes to OVN release management. This thread is specifically
to discuss the support lifetime of OVN releases.
Current documentation discusses two ideas with regards to version
support lifetime
* LTS releases receive two years of bugfixes, and an additional year of
critical/security fixes.
* When an issue is fixed in OVN, we fix it in main first, then backport
all the way to the most recent LTS.
In this thread, I propose the following revisions should be made to the
OVN documentation:
* "Supported" versions refers to versions for which we are providing
minor releases [2] . "Unsupported" versions are versions for which we
are no longer providing regular minor releases. An unsupported version
may still receive changes to its development branch, but there will be
no further releases made on that branch.
* Standard support (non-LTS) versions will be supported for one year
from the time of its initial release.
* Instead of backporting fixes to the most recent LTS, we will backport
fixes to the previous 4 branches. This means that we will be providing
fixes to branches of unsupported versions.
* Critical/security fixes should be backported to all branches between
the current main branch and the branch corresponding to the LTS version
that is currently receiving critical/security fixes. This means that we
will be porting the fix to unsupported versions. The fix will be present
in those branches, but we will not create releases for those unsupported
versions.
Please let me know if you have questions or objections to these policy
changes.
Thanks,
Mark Michelson

the current policy regarding minor releases.
