+* Field compression is no longer supported. Fields that were formally
+ compressed will be uncompressed as index segments are merged. For
+ shorter fields, this may actually be an improvement, as the compression

+ compression, and as a result, once you upgrade, previous versions of Solr
+ will no longer be able to read the index.
