Rahul Goswami updated SOLR-18143:
---------------------------------
    Description: Lucene 10.4 released last week and contains several important 
Vector search related changes. It also contains a critical enhancement which 
moves the MIN_SUPPORTED_VERSION (Version.LATEST-1) check to the segment level 
instead of requiring that the index be created in version no older than 
MIN_SUPPORTED_VERSION. This is necessary to be able to open the indexes 
originally created in Solr 8.x and upgraded via the recently introduced index 
upgrade capability in Solr.  (was: Lucene 10.4 released last week and contains
