Changes 5.5.51:
Bugs Fixed

Replication: When using statement-based or mixed binary logging format with \ 
--read-only=ON, it was not possible to modify temporary tables.

MySQL Server upgrades performed using RPM packages failed when upgrading from \ 
MySQL 5.1 Community to MySQL 5.5 Community or MySQL 5.1 Commercial to MySQL 5.5 \ 
Commercial.

A buffer overflow in the regex library was fixed.

Certain arguments to NAME_CONST() could cause a server exit.

Installing MySQL from a yum or zypper repository resulted in /var/log/mysqld.log \ 
being created with incorrect user and group permissions.

If a stored function updated a view for which the view table had a trigger \ 
defined that updated another table, it could fail and report an error that an \ 
existing table did not exist.

If an INSTALL PLUGIN statement contained invalid UTF-8 characters in the shared \ 
library name, it caused the server to hang (or to raise an assertion in debug \ 
builds).

For multibyte character sets, LOAD DATA could fail to allocate space correctly \ 
and ignore input rows as a result.
