Breaking changes:

Renamed MongoDB.BsonLibrary namespace to MongoDB.Bson (same for DLL name)
Renamed MongoDB.CSharpDriver namespace to MongoDB.Driver (same for DLL name)

Serialization related changes:

Added IBsonSerializationProvider and created the DefaultSerializer
Added BsonDateTimeOptionsAttribute (with Representation, DateOnly and Kind parameters)
Added RootClass parameter to BsonDiscriminatorAttribute
Added IdGenerator and Order parameters to BsonIdAttribute
Added BsonKnownTypesAttribute
Replace BsonUseCompactRepresentationAttribute with more general BsonRepresentationAttribute
Added a number of convention interfaces and a ConventionProfile class
Removed IBsonPropertySerializer (but added Serialize/DeserializeElement to IBsonSerializer)
Implemented serializer for Arrays (one dimensional for now)
Implemented serializers for Collection classes (legacy and generic)
Implemented serializers for Nullable types
Implemented serializer for object (primarily to handle reading the discriminator on deserialization)
Modified BsonClassMap to support fields as well as properties
Added MapField and MapMember to BsonClassMap (in addition to existing MapProperty)
Added MapIdField, MapIdMember and MapIdProperty to BsonClassMap
Added IDiscriminatorConvention and two standard implementations (Scalar- and HierarachicalDiscriminatorConvention)
Removed requirement that POCO class have a public default constructor for deserialization
Added IIdGenerator convention

Added support for generic serializer definitions (closed types created as needed at runtime)
RegisterSerializer now registers serializers using a Type/SerializationOptions pair as the key
Renamed Bson class to BsonConstants (to work around clash with new Bson namespace)
Recommended name for BsonNull constant is now BsonNull.Value (patterned after DBNull.Value in .NET)

Driver related changes:

Insert/Save now handle Id field detection/assignment in POCO classes
Implemented MongoDBRef class
Implemented FetchDBRef and FetchDBRefAs
Moved RenameCollection method from MongoServer to MongoDatabase
