 Fixed unlikely caching bug when doing a join without keys. In this case
 the last used field for a table always returned @code{NULL}.
+@item
+Added options to make @code{LOAD DATA LOCAL INFILE} more secure.
+@item
+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.
