it is my understanding that users are encouraged to reindex whenever there's a major (N+1) Lucene/Elasticsearch update...
And reindexing is probably required for upgrading to major version N+2 afterwards, because Lucene (or ES) is not guaranteed to be ableÂread index from version N-2...(I forgot which one, or maybe both, I have to re-read my own mails :-)
So it would be a good thing to mention reindexing in the release notes

Good stuff, thanks Andreas. I'm not really familiar with the various lucene and solr versions, will this have any influence on existing users with existing indexes? Or will it seamlessly upgrade?

I'll have a closer look this weekend.
