So why bother? Firstly, I am able to re-organise some of the code, making it easier for me to maintain in future. Second, the new XML format is more "industry standard," making it easier to read. Finally, it paves the way for an upcoming project I have in the works. You'll have to wait and see what it is, but I think you'll like it...
There are also a couple of bug fixes and new features coming up. Take a look at the three tasks marked as "started" on the UserVoice page.
As before, I'll post a pre-release version up in the forum for the brave of heart to have a go with before the final release. This should help make sure there are no glaring problems.
