This release fixes two problems.
The first one is the test for MySQL V 4.0.2 or above to enable AES encryption was not working properly. The code has been changed to require a compile time parameter (-D AES) to enable AES encryption (only available with MySQL 4.02 or later). The documentation was also updated to reflect this change.
The second change was to fix a minor bug in the AES encryption. The module was not handling the salt field properly.
