Remember the discussion thread about a Lucene upgrade that includes a Codec update, and needing to broadcast this fact in the upgrade notes page? This markdown file should explicitly add this step.

I don't think I remember a discussion thread regarding this. Quick search on the dev list wasn't helpful either. No mention of codec changes in the current olr/solr-ref-guide/modules/upgrade-notes/pages/major-changes-in-solr-10.adoc either. Do you have a link to the discussion ?
