C# Driver Version 1.3 Release Notes
===================================
This release of the C# driver has fewer changes than most releases before it. The primary goal of this release is to support
new features introduced by the 2.0 server release, and to fix bugs reported since the 1.2 C# driver was released.
Highlights
Support for new features introduced by 2.0 server release
A number of minor bug fixes
One important bug fix for Disconnect (which caused the connection pool to get jammed)
Breaking changes (mostly internal and/or low level)
Slight changes in Equals and == for BsonValues
Equals no longer does numeric coercion and uses Equals (instead of ==) to compare values
Comparing BsonDouble NaN values now mirrors Equals and == behavior of System.Double
Operator == (and !=) still coerce different numeric types to a compatible type before comparing
Calling BsonMemberMap.SetDefaultValue no longer automatically sets SerializeDefaultValue to true
GetIndexes now returns a GetIndexesResult (original return value is still available as result.RawDocuments)
JIRA Issues resolved
--------------------
The list of JIRA issues resolved in this driver release can be found at https://jira.mongodb.org/secure/IssueNavigator.jspa?mode=hide&requestId=11131

BsonNull.cs
BsonObjectId.cs
BsonRegularExpression.cs
BsonString.cs
BsonSymbol.cs
BsonTimestamp.cs
BsonUndefined.cs
Added implementations of operator == and operator !=
Equals now checks type of rhs
BsonDocument.cs
Added implementations of operator == and operator !=
Equals now checks type of rhs

BsonDouble.cs
Added implementations of operator == and operator != (now handles NaN same as System.Double)
Equals now uses Equals instead of == to compare values (now handles NaN same as System.Double)
Equals now checks type of rhs
Equals no longer does numeric coercions (now only == and != do)
BsonElement.cs
Equals now checks type of rhs
BsonInt32.cs
BsonInt64.cs
Added implementations of operator == and operator !=
Equals now checks type of rhs
Equals no longer does numeric coercions (now only == and != do)
BsonValue.cs
Operator == and != now call virtual method OperatorEqualsImplementation
Default implementation of OperatorEqualsImplementation calls Equals, but numeric subclasses override to do numeric coercions
BsonDictionaryOptionsAttribute.cs
New attribute used to choose the representation to use when serializing a Dictionary
DictionarySerializationOptions.cs
New serialization options used to choose the representation to use when serializing a Dictionary
DictionaryGenericSerializer.cs
