Full details of enhancements / fixes included in M3 can be found in the GitHub project: https://github.com/paulswithers/openlogjava/issues?milestone=2&state=closed
#8 Fix for various uncaught exceptions that had different Java classes for error.getCause() or error.getCause().getCause().
#9 Fix for error message greater than 32k (happens if error is in a large SSJS library)
#10 Enhancement to logging to an OpenLog that's a mail-in database. Use xsp.openlog.email for the email address to mail to. You should not need an OpenLog database on the server, because the message is created in the mail.box. (Domino automatically handles re-directing mail.box to mail1.box etc if multiple mail boxes are in use on the server.)
