1. #230402 repairing CCK integration and changing strategy a bit. Now only checkboxes, selects and radio buttons generate facet blocks automatically. Other CCK fields can have facets and facet blocks by implementing hook_apachesolr_cck_field_mappings
2. #248552 add explicit check for required field nid
   #230377 add results sorting to ApacheSolr. There is now a block that allows you to sort by Title, Type, Author, and Date. The solrsort GET parameter can additionally be used to sort by comment count, uid and nid, as well as any CCK text fields that are indexed. This change requires you to update the schema.xml file in your Solr installation, restart Solr, and re-index your site.
3. #248882 Fixed problem with indexing when no solr instance available
4. #248881 Adding hook_requirements so that Solr server status can be monitored more easily by administrator
5. #247358 created a function, apachesolr_has_searched, that acts a semaphore to only do Solr related stuff if there has been a search (like generate blocks). Fixed form_alter (hacked it, really) so that it doesn't instantiate a Solr object every time the search form is built (like on q=search/node). See the issue for discussion of deeper problem.
