Shawn Heisey commented on SOLR-12243:
-------------------------------------
In general, we make changes to master. Then we backport to the current stable
development branch.
The current stable development branch is branch_7x.
If there are any releases currently underway or due to be underway shortly, and
the release manager for that version agrees with the change, the change MIGHT
be backported to a more specific branch, such as branch_7_3.
At some point in the future that has not yet been determined, we will create
branch_8x from master and begin the process of releasing 8.0.0. At that point,
work on branch_7x is likely to stop.
