I just uploaded a new version, RP2pr3. You can get it from the Download link in the upper right corner of the blog.
Major new features
Tubes now alternate between valid same-length destinations, allowing fair item distribution.
A preview version of Blutricity.
A non-colored bundled cable.
Transposers and Filters can insert or extract from storage minecarts.
New Item Detector block.
Ore Dictionary support.
Transposer passive actions switch off when powered, allowing the Transposer to be used as a valve.
A major secret feature.
Some recipes are temporary, and a few have changed.
Game balance is still not finalized.
Volcanos and Rubber Trees are still using an even distribution.
Creative Mode is still not supported. RedPower blocks can’t be broken in creative mode.
The Blutricity energy network loses too much power and has too much line sag.
A small save change will make jacketed wires in inventory invalid. Jacketed wires in the world will be fine.
Spilling items around full chests.
Basalt covers preview as bedrock
Bad ejection positions
Filters accepting blocks backwards.
Items entering stuffed up transposer.
Not filtering on the sucking cone?
Can disable silver, tin, copper generation
Add a “autoAssign” option to the config file, to prevent the IDs from wandering.
