This is a bug fix and performance improvement release for the Couchbase .NET SDK 2.0, following up on the GA release 2.0.0 in early December last year. The transport layer has been rewritten to use SocketAsyncEventArgs instead of the older asynchronous Socket API, reducing garbage collection issues. A single contiguous fixed buffer is used for all SocketAsyncEventArgs instances, eliminating problems with garbage collection. New bulk methods have been added for removing keys in parallel, which can be useful in real-world scenarios. Several major bug fixes have also been included, addressing issues such as CAS changes and TTL follow rules. The release includes contributions from the community through Pull Requests, GitHub tickets, and forum discussions. The Couchbase .NET SDK 2.0 packages are available on NuGet, S3, or can be pulled directly from master using the "2.0.1" tag.
