Bug fixes and improvements introduced in MongoDB and included in Percona Distribution for MongoDB are the following:

• Fixed the flow for converting a replica set into a sharded cluster b adding support for the drivers to communicate the signed $clusterTimes to shardsvr replica set before and after the addShard command is run.
• Fixed the issue with the incorrect output for the query where the $or operator rewrites the $elemMatch extra condition.
• Blocked the $group min/max rewrite in timestamp if there is a non-meta filter.
• Disallowed the retry to forcibly evict the page during reconciliation.

Percona Backup for MongoDB 2.2.1 provides the ability to increase the wait time for physical backup to start. This eliminates the PBM failure when creating $backupCursor takes longer than usual.
