This release opens the new 7.5 development branch. Most importantly, this version provides certificate-based authentication for RELP. It also includes mmfields, a module that can be used to parse CEF and other similar delimited formats. BSD-support has been improved and imjournal has been hardened to prevent corrupt journal databases from spamming the system too much.

As always, feedback is appreciated.
