upgrade from Solr 8 11.1 to 8 11.3 reindex

[Bill Okara]

Hi,

do collections need to be re-indexed when upgrading Solr from 8.11.1 to 8.11.3?

I was under the impression that reindex would not be needed since it’s just a 
minor version upgrade, but would like to confirm that’s true.

also,
should  the <luceneMatchVersion> be changed to 8.11.3 when upgrading, or can I 
leave it as 8.11.1？

Thanks,
Bill
