Version 2.1.4 of the Couchbase .NET SDK has been released, primarily focusing on bug fixes and minor improvements, with plans for version 2.2.0 to offer full support for Multi-Dimensional Scaling (MDS) and N1QL, along with enhanced durability. This release provides beta support for N1QL and partial support for MDS, which requires a single Couchbase Server 4.0 Beta instance with Data, Indexing, and Query services configured. Notable bug fixes address issues such as connection leaks, N1QL query errors, and high latency on asynchronous operations, while improvements include feature testing for large data appends and unit test refactoring. The SDK is accessible for download via NuGet or GitHub.
