+ === document and view file compression ===
+ 
+  * The new optional compression of disk files requires an upgrade of the on-disk format
(5->6) which occurs on creation for new databases and views, and on compaction for existing
ones
+  * This format is not supported in previous versions, so rollback would require replication
to the previous CouchDB release, or restore from backup
+  * adding {{{compression = none}}} to your {{{local.ini [couchdb]}}} section disables compression
but the ondisk format will still be upgraded as above
+  * file compression is enabled by default
