AI summary: FTB has added the Refined Wireless Upgrade and Replication AE2 Bridge mods to expand your automation setups. Replication receives a massive overhaul: machines now run significantly faster, and you can scan and duplicate rare items like Nether Stars, Elytras, and Dragonsteel. Combat also gets a boost with an armor-penetration mechanic for unarmed attacks, plus a new keybind to toggle sword blocking so you can freely use off-hand bows.
