Re: [jira] [Commented] (LUCENE-8347) BlendedInfixSuggester to handle

Posted by Erick Erickson <er...@gmail.com>.
The branches where development happens are master and branch_7x.
Typically we pull and work on master and whoever commits it backports
to 7x if appropriate.
So from your perspective, if you're doing development just use "master".
If you're trying to patch your local version, pull that branch. For
instance, if you're working on Solr 7.2.1, then pull branch_7_2
Best,
Erick
