| =================================== | ||
|
|
||
| This is a major release featuring support for server 2.2. The major change is | ||
| support for[read preferences](http://docs.mongodb.org/manual/applications/replication/#read-preference) | ||
| allowing tag based granularity for selecting servers to send commands and | ||
| queries to. In addition, we have added support for SSL and a helper method | ||
| for the new aggregation framework. | ||

||
| These release notes describe the changes at a higher level, and omits describing | ||
| some of the minor changes. | ||
|
|
||
| Breaking changes | ||
| ---------------- | ||
|
|
||
| - ConnectWaitFor has been removed and replaced with read preferences. Anyone | ||
| using the ConnectWaitFor enumeration will need to change their code. | ||
| - Commands are no longer always sent to primaries. If you are expecting this | ||
| behavior, ensure that your read preference is set to Primary. | ||

| - ConnectWaitFor has been removed and replaced with read preferences. Anyone | ||
| using the ConnectWaitFor enumeration will need to change their code. | ||
| - The serialized representation for a C# null of type BsonNull has been changed | ||
| from { $csharpnull : true } to { _csharpnull : true } to work around limitations | ||
| of the server. Existing data will still be correctly deserialized but new data | ||
| will be written in the new format. This is very unlikely to affect you because | ||
| it is very unlikely you have any properties of type BsonNull in your classes. | ||
|
|
||
| New features | ||
| ------------ | ||
|
|
||
| - There is a new \[BsonSerializer] attribute that can be used to specify which | ||
| serializer to use for a class. | ||
| - Instances of ReadOnlyCollection are now serializable/deserializable. | ||
| - Queries involving Mod now work with 64-bit integers also. | ||
| - Support for TTL collections (see IndexOptions.SetTimeToLive). | ||
| - Simple helper method for aggregation framework (see MongoCollection.Aggregate). | ||
| - SlaveOK has been deprecated and replaced with the more flexible ReadPreference options. | ||
| - Support for SSL connections. | ||
| - Improved support for LINQ queries from VB.NET. | ||
| - Support for connecting to multiple mongos’ with load balancing |
