Hi Jonathan- The main branch is the tip of development, and what will eventually become 10.0. It can use a later version of Java, make (some) non-backwards-compatible API changes, etc. branch_9x tracks the latest 9.x release, and must run on the version of Java supported by 9.x releases, must be API backwards-compatible, etc. The general approach is to make changes against main, and then backport those changes to branch_9x in a 9.x friendly way if possible. Sometimes a change on main is complex enough that backporting in a 9.x friendly manner isn't really feasible, in which case the change will be released with 10.0. I'm sure I'm leaving out some details, but hopefully this is helpful. You may also find this reference useful: https://cwiki.apache.org/confluence/display/LUCENE/BackwardsCompatibility
