Packaging: Some builds on Solaris 64-bit failed because the packages exceeded the 2GB limit for the SVR4 installation layout. Now such packages are built without the embedded versions of mysqltest and mysql-client_test to save space. (Bug #14058643)
If the Transaction Coordinator aborted a transaction in the “prepared” state, this could cause a resource leak. (Bug #14208924)
An error handling routine in the local query handler used the wrong code path, which could corrupt the transaction ID hash, causing the data node process to fail. This could in some cases possibly lead to failures of other data nodes in the same node group when the failed node attempted to restart. (Bug #14083116)
When attempting to connect using a socket with a timeout, it was possible (if the timeout was exceeded) for the socket not to be set back to blocking. (Bug #14107173)

Attempting to add both a column and an index on that column in

this issue affected only the mysqld shipped

operations are supported.

When an NDB API application called
again after the previous call had returned end-of-file (return
code 1), a transaction object was leaked. Now when this happens,
NDB returns error code 4210 (Ndb sent more info than
length specified); previouslyu in such cases, -1 was
returned. In addition, the extra transaction object associated
with the scan is freed, by returning it to the transaction
coordinator's idle list.
