## Stability 

• SERVER-12061 367 Do not silently ignore read errors when syncing a replica set node 

• SERVER-12058 368 Primary should abort if encountered problems writing to the oplog 

## Querying 

• SERVER-16291 369 Cannot set/list/clear index filters on the secondary 

• SERVER-15958 370 The “isMultiKey” value is not correct in the output of aggregation explain plan 

• SERVER-15899 371 Querying against path in document containing long array of subdocuments with nested arrays causes stack overflow 

• SERVER-15696 372 $regex , $in and $sort with index returns too many results 

• SERVER-15639 373 Text queries can return incorrect results and leak memory when multiple predicates given on same text index prefix field 

• SERVER-15580 374 Evaluating candidate query plans with concurrent writes on same collection may crash mongod 

• SERVER-15528 375 Distinct queries can scan many index keys without yielding read lock 

• SERVER-15485 376 CanonicalQuery::canonicalize can leak a LiteParsedQuery 

• SERVER-15403 377 $min and $max equal errors in 2.6 but not in 2.4 

• SERVER-15233 378 Cannot run planCacheListQueryShapes on a Secondary 

• SERVER-14799 379 count with hint doesn’t work when hint is a document 

## Replication 

• SERVER-16107 380 2.6 mongod crashes with segfault when added to a 2.8 replica set with >= 12 nodes. 

• SERVER-15994 381 listIndexes and listCollections can be run on secondaries without slaveOk bit 

• SERVER-15849 382 do not forward replication progress for nodes that are no longer part of a replica set 

• SERVER-15491 383 SyncSourceFeedback can crash due to a SocketException in authenticateInternalUser
