NOTICE: Data Format Changes

Couch users,

This is just a warning that the latest updates to svn trunk (r690668)
are backwards-incompatible with prior versions of CouchDB. If you have
data that you don't want to lose, please follow the suggestions on
http://wiki.apache.org/couchdb/BreakingChanges to dump you database
from the old version, before upgrading and reloading into the new
version.

An alternative process would be to launch a the new-version of CouchDB
from the source directory (see
http://wiki.apache.org/couchdb/Contributing for information on running
from source). You should ensure that this version is not using the
same data directory as your existing install. Then you should be able
to replicate existing databases to the new version. When your
replication is done, you should shutdown both instances, move your
original data directory aside, and `make install` the new version.
Then you move the newly created data directory into place where the
old one was, and boot CouchDB normally. You should see your existing
databases are available.

To be on the safe side, please make a backup of your data directory
before beginning this process.

Chris
