Man, I'm not going to figure out what changes you've made against 2.44.1 and then port those up to the trunk. I do enough of that in my day job. You want to make a contribution? Grab the code from the SVN trunk, make changes to it, and send me the SVN diff file. I know you know all about that, since you already asked very specific questions about the process in this very thread!
If you don't want to submit your changes to the trunk, you can just release a modified EXE.
