高性能的Key-Value数据库Redis 5.0.2发布下载了，新版本修复了两个关于Streams消费者的问题，可以在访问历史记录时由XREADGROUP复制项目的组，以及XREADGROUP可以报告某些历史记录的另一个错误，即使待添加的消费者列表为空。目前已解决了这两个问题，并进行了单元测试以避免出现回归错误。此外，该版本还修复了集群模式下redis-cli的一些问题。最后关于FreeBSD和DragonFly的一些构建问题现在也已经解决。
升级紧急程度 CRITICAL if you use streams and consumer groups.HIGH if you use redis-cli with Redis Cluster.LOW otherwise.
Redis 5.0.2发布详情 Welcome to Redis 5.0.2. This release fixes two issues with Streams consumer groups, where items could be returned duplicated by XREADGROUP when accessing the history, and another bug where XREADGROUP can report some history even if the comsumer pending list is empty. Both problems were addressed and unit tests to avoid regressions implemented. Moreover this release fixes some issue with redis-cli when in cluster mode. Finally some FreeBSD and DragonFly build problems are now resolved. The list of the commits is below.
