The new anti-piracy is still not cracked/removed. You're allways having 0.5 damage to everything. Try hitting a mob with sharpness 1000, the total damage will be 0.5 =))
Lucky me I had Plugman which helped me find what plugin does that. :)
Excellent release, worked perfectly on my server with no issues whatsoever. It turns out my permissions plugin was bugged, had to update it because of Lib's Disguise :P
