Changes
This is a new major release, which has a 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.
We also have introduced some deprecation notices for features and methods that
are going to disappear in version 2 of the driver, which we plan to release
before the end of the year.
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)
Known issues (to be addressed before 1.3.0):
- Authentication has not been implemented it, so this release will only work
for installations without authentication enabled.
- Support for connections to multiple mongos nodes is not implemented yet.
- It has not been tested on anything but Linux.
