Couchbase has released version 2.2.8 of its .NET SDK, which primarily includes bug fixes and Developer Previews (DP) for upcoming features in support of Couchbase Server 4.5. This version introduces a preview of Full Text Search, enabling search capabilities over JSON documents similar to Elastic Search, though it is not yet suited for production use. Another key feature previewed is AT_PLUS for N1QL Queries with MutationTokens, facilitating the "Read Your Own Writes" (RYOW) functionality to ensure up-to-date indexes. Additionally, the release addresses several technical tasks, bug fixes, and improvements, such as refactoring WebRequest/WebResponse to System.Net.Http namespace classes and enhancing vBucket Retry Logic. Further detailed discussions on these features and improvements are anticipated in future blog posts.
