Bug
- [SERVER-3112] - mongo* tools logs should not log to stdout (broken w/--out -)
- [SERVER-3641] - support mongostat through mongos with authentication
- [SERVER-3672] - use min(majority, all "real" nodes) for majority
- [SERVER-3763] - when one shard goes down, mongos starts returning failure in getlasterror for all the shards, to already connected client.
- [SERVER-3817] - Increment opcounters for bulk insert
- [SERVER-3939] - Rollback is trying to log something in the oplog
- [SERVER-4115] - copyCollectionFromRemote needs to authenticate
- [SERVER-4238] - Make sure authentication always happens when a ScopedConn connects
- [SERVER-4387] - command should force reload of config data after multiple stale config exceptions
- [SERVER-4399] - mongos doesn't always update shards in response to replica set changes
- [SERVER-4400] - attempt to record query plan for a dropped cursor triggers bad file number assertion
- [SERVER-4401] - query optimizer cursor may return partial result set for a $or query if the last index match for a $or clause is deleted while it is "current"
- [SERVER-4474] - Initial sync should ignore capped collection dup key error, too
- [SERVER-4546] - Oplog replay can assert on initial sync if there's no _id index on a capped collection
- [SERVER-4547] - Disable full restore of sharded cluster
- [SERVER-4591] - MongoDB 2.0.2 fails to build: 'str' object has no attribute 'rpartition'
- [SERVER-4626] - If update does not contain an _id in criteria, sync apply can assert and get stuck
- [SERVER-4634] - --use-system-all (and --use-system-snappy?) don't actually use system snappy
- [SERVER-4643] - one of the shard is down
- [SERVER-4665] - Querying against sparse index creates bad state, affecting later queries
- [SERVER-4695] - getLog auth checks needs backport
- [SERVER-4699] - mongos can segfault after primary failover
- [SERVER-4712] - Shards crash fairly frequently when memory is low
- [SERVER-4714] - ScopedConn is segfaulting
- [SERVER-4745] - Figuring out which shard to send a query to takes a long time when doing large $in queries on the shard key
- [SERVER-4749] - fix concurrency api when using openssl
- [SERVER-4765] - sharded currentOp doesn't actually pass query
Improvement
- [SERVER-2612] - support logRotate under windows
- [SERVER-4673] - Don't lock authenticate command if we don't need to
- [SERVER-4780] - Improve Memory Leak Warning Message
