The latest beta release of the Couchbase C SDK library introduces several enhancements and fixes over its previous developer preview version, including the implementation of HTTP keepalive for views, which allows multiple view requests to utilize the same TCP connection, thus improving efficiency. The API documentation has been updated, particularly for the v3 API, and the dsn field has been renamed to connstr. Additionally, the input format for manpages has been transitioned from asciidoc to ronn, a markdown-like syntax, allowing better integration with Doxygen's markdown parser for improved documentation visibility. Furthermore, RPM packages are now available for EL7, extending the library's support for CentOS 7, following community requests, while packages for Ubuntu Trusty/14.04 have been available since the developer preview.
