Changes in release 3.23.49
--------------------------
* Don't give warning for statement that is only a comment; This is
needed for `mysqldump --disable-keys' to work.
* Fixed unlikely caching bug when doing a join without keys. In this
case the last used column for a table always returned `NULL'.
* Added options to make `LOAD DATA LOCAL INFILE' more secure.
* MySQL binary release 3.23.48 for Linux contained a new glibc
library, which has serious problems under high load and RedHat
7.2. The 3.23.49 binary release doesn't have this problem.
* Fixed shutdown problem on NT.
