+mongodb (1:2.6.11-0.1) UNRELEASED; urgency=medium
+ When upgrading MongoDB to 2.6, keep in mind that only upgrades from 2.4 are
+ supported. If you wish to upgrade from previous MongoDB versions, you have
+ to upgrade to 2.4 first.
+ Furthermore, MongoDB 2.6 now enforces document constraints in a more strict
+ manner, specifically:
+ * Index key length limit: 2.6 implements a stronger enforcement of the
+ limit on index key. Index creation, document inserts and updates may
+ fail if an index entry exceeds the limit.
+ * Field name restrictions: Updates no longer support saving field names
+ containing a dot ('.'), or beginning with a dollar sign ('$'). Note that
+ these restrictions on field names have been introduced in MongoDB 2.2.
+ To check your existing database for compatibility with MongoDB 2.6, run
+ $ db.upgradeCheckAllDBs()
+ on a MongoDB 2.6 client connected to your existing MongoDB 2.4 database.
+ Additionally, MongoDB 2.6 introduces a new authorization model, which
+ requires manual action to migrate to.
+ For a full list of changes as well as instructions on how to upgrade
+ standalone servers and replica sets, see:
