Percona XtraDB Cluster 5.6.42-28.30 发布

Percona XtraDB Cluster 5.7.17-27.20 发布了，二进制文件可在 下载区 或  软件仓库 中下载。

Percona XtraDB Cluster 5.7.17-27.20 基于以下这些项目：

• Percona Server 5.6.42

• Codership WSREP API release 5.6.42

• Codership Galera library 3.25

Fixed Bugs

• PXC-2281 : Debug symbols were missing in Debian dbg packages.

• PXC-2220 : Starting two instances of  Percona XtraDB Cluster on the same node could cause writing transactions to a page store instead of a galera.cache ring buffer, resulting in huge memory consumption because of retaining already applied write-sets.

• PXC-2230 :  rgcs.fc_limit=0 not allowed as dynamic setting to avoid generating flow control on every message was still possible in  my.cnf due to the inconsistent check.

• PXC-2238 : setting  read_only=1 caused race condition.
