1.3.0RC1 This is the first release candidate of the 1.3 series. The 1.3 series are
a major improvement with a completely rewritten connection handling backend. It has been
rewritten to form a new improved framework for handling connections. On top of
this new framework, new functionality is also implemented to provide read
preference support that comes with MongoDB 2.2. The new framework no longer has
the concept of a connection pool, but instead make sure there is only one
connect per node/db/username.

New major features in this release to support the MongoDB 2.2 release:

- Support for the aggregation framework through the aggregate() helper.
- Support for read preferences and read preference tags (See:
http://docs.mongodb.org/manual/applications/replication/#replica-set-read-preference)

tuned.

* Creating new instances of MongoId is faster.

1.1.0 Replica set reads can be distributed to slaves. This can be done by calling
setSlaveOkay on a connection, database, or collection. You can see the slave
that will be used with Mongo::getSlave and see/refresh the set status with
Mongo::getHosts.You can now see the server used for a query with
MongoCursor::info.
Added mongo.no_id php.ini option.
Better exception is thrown when the database is corrupt.
Fixed MongoDB::createCollection parameter parsing on 64-bit machines.

checks on all methods, added fields param to GridFS::findOne. Fixed some
error messages (authentication and BSON deserialization) and handling (for
large messages and field names passed as integers). Fixed a couple of double
frees and an incorrect cursor boundry condition. Added MongoId::__set_state
and MongoId::getHostname (to see the hostname hashed for unique ids).
1.0.7 The bug fix release! A zillion bugfixes and the new static
MongoCursor::$timeout property for setting a default timeout for requests.
Bug fixes include count error handling, fixing double frees with BSON errors
and ensureIndex, a mutex fix for FreeBSD, catching socket connection errors
(William Volkman), database commands propagate exceptions, and cursor killing
is more efficient.
1.0.6 Allow MongoCollection::ensureIndex to create 2D indexes.
Added MongoCursor::fields().
Fixed for big endian machines.
Removed debug statements.
1.0.5 Mutex fixes (especially on Windows) and improvements (failures throw exceptions).
New Cursor::info() function, which gives the query, fields, namespace, limit, and
skip (by Cesar Rodas)
Added safe option for remove, update, batch, and gridfs insert methods.

grouping key to use keyf.
