The recent release of version 1.3.6 of the .NET SDK by Couchbase focuses on bug fixes and maintenance, with significant contributions from the community, which are highly valued in this open-source project. Key improvements include fixing a bug related to missing username and password in API calls, adjusting the verbosity of logging in the heartbeat component, addressing clock drift issues between client and server, and enhancing the disposal process of internal components to prevent NullReferenceExceptions. Despite fewer new features in the 1.X series due to a development shift towards the 2.X series and a new LINQ provider in anticipation of Couchbase Server 3.0, developer previews have been released, with more updates expected soon.
