So I just posted RedPower 2 Prerelease 4, for Minecraft 1.0.0. Download link is up top, as always.
Major New Features
New Blutricity energy net.
Added Battery Boxes.
Added Sorting Machine.
Added Paint Cans/Brushes.
Added Redstone Tubes.
Added partial support for Creative mode.
Blutricity power is a little “springy”. When you connect it, you’ll see line transients if you repeatedly measure with a voltmeter. This is normal.
There are probably issues with TMI. Don’t bother reporting them. I plan to fix TMI interaction in pr4b.
I have no idea what happens if you to enchant RP items.
Forge 1.2.0 has a bug with repair recipes. Just don’t use them with RP items. The next Forge version will fix this.
Rubber trees now have a fast mode.
Fixed infinite backstuffing.
Fixed machine freezing.
Fixed covers on logic turning into cobble.
Fixed ore generation patterns.
Fixed a major loss of framerate in SMP with tubes.
