The most comprehensive list is CHANGES.txt. I'd look at the Solr one first (this is the one in the at the root level of your installation directory).
If you have the source code checked out, there's a CHANGES.txt in the <source dir>/solr and <source_dir>/lucene. All the changes refer you to the Solr and Lucene JIRAs that they came from and there's a wealth of detail in those discussions.
