Since BC isn't updated to 1.6.x yet, I can try to push a quickish update to 1.5.x with no new features then start working on a 1.6.x version, or ignore 1.5.x and start working on a 1.6.x and try to get in some new stuff to be released when BC is updated. The former means you will have an update soonish but nothing new, the ladder means no update for a while, but probably some new stuff when there is a update. I'm not sure how many people have updated to 1.5.x, I haven't due to redpower 2. So, let me know what you would like more.
I'll check back and tally the votes on Saturday.
If you mind, do pls a quickish update to 1.5.2. That would be nice of you.
