Changes in release 3.21.27
--------------------------

   * Added user level lock functions `GET_LOCK(string,timeout)',
     `RELEASE_LOCK(string)'.

   * Added `opened_tables' to `show status'.

   * Changed connect timeout to 3 seconds to make it somewhat harder
     for crackers to kill `mysqld' through telnet + TCP/IP.

   * Fixed bug in range optimizer when using `WHERE key_part_1 >=
     something AND key_part_2 <= something_else'.

   * Changed `configure' for detection of FreeBSD 3.0 9803xx and above

   * `WHERE' with string_column_key = constant_string didn't always find
     all rows if the column had many values differing only with
     characters of the same sort value (like e and e').

   * Strings keys looked up with 'ref' were not compared in
     case-sensitive fashion.

   * Added `umask()' to make log files non-readable for normal users.

   * Ignore users with old (8-byte) password on startup if not using
     `--old-protocol' option to `mysqld'.

   * `SELECT' which matched all key fields returned the values in the
     case of the matched values, not of the found values. (Minor
     problem.)
