MariaDB 10.1.4 发布了，下载地址：https://downloads.mariadb.org/mariadb/10.1.4/
这是 MariaDB 10.1 的第二个 Beta 测试版本，也是第 5 个发行版本，该版本值得关注的改进内容包括：
- Encryption: 很多跟表和表空间加密的改变在该版本得以实现，详情请看 updated documentation和 nice summarization here
- Consistent support for IF EXISTS, IF NOT EXISTS, and OR REPLACE clauses was added to:
- New server variable: New server variable enforce_storage_engine
- New status variable: New status variables to show the number of grants on different objects (Also see Status Variables Added in MariaDB 10.1)
- New status variable: New status variables to track MASTER_GTID_WAIT time. This feature was contributed by Daniel Black.
- New status variable: New status variable Slave_skipped_errors. This feature was contributed by Daniel Black.
- Performance: xid cache scalability was significantly improved (by using lock-free hash)
- Performance: VIEW definitions are now cached in memory (in the table definition cache)
- Replication: Starting with this release, commits in certain instances in parallel replication complete immediately, avoiding losing throughput when many transactions need conflicting locks. See binlog_commit_wait_count.
