Functionality added or changed:

  • The libedit library was upgraded to version 2.11. (Bug#42433)

Bugs fixed:

  • Security Fix: Using an XPath expression employing a scalar expression as a FilterExpr with ExtractValue() or UpdateXML() caused the server to crash. Such expressions now cause an error instead. (Bug#42495)

  • On the IBM i5 platform, the MySQL configuration process caused the system version of pthread_setschedprio() to be used. This function returns SIGILL on i5 because it is not supported, causing the server to crash. Now the my_pthread_setprio() function in the mysys library is used instead. (Bug#42524)

  • The SSL certficates included with MySQL distributions were regenerated because the previous ones had expired. (Bug#42366)

  • User variables within triggers could cause a crash if the mysql_change_user() C API function was invoked. (Bug#42188)

  • Some queries using NAME_CONST(.. COLLATE ...) led to a server crash due to a failed type cast. (Bug#42014)
