Couchbase 4.5 开发者预览版发布
Couchbase 4.5 开发者预览版发布，Couchbase Server （前身是 Membase） 是一个分布式的面向文档的 NoSQL 数据库管理系统，该系统联合了 CouchDB 的简单和可靠以及 Memcached 的高性能以及 Membase 的伸缩性。
对于开发者来说，该版本值得关注的新特性包括：
Query Workbench – 内建的查询编辑器
Full-text Search – support for term, fuzzy, phrase, match, and prefix queries has been added – faceting, scoring, and highlighting, too.
Sub-document API – enables clients to add, remove, and modify individual fields (or read them), including objects and arrays, without reading and writing the entire document
Array Indexing – index specific fields of elements within nested arrays to improve query performance
Extended N1QL joins – support a new query optimization for filtering the right side first, with an index, resulting in added flexibility and improved query performance
Query Profiling and Monitoring – monitor active queries and connections as well as profile queries to identify and diagnose performance issues
同时我们还提供了 Debian 8 的构建版本，详情请看 existing wide list of platforms
