I'm using Avisynth+ but I'll check plugins version. However I'm pretty sure they're up to date.
UPDATE:
I'm using 0.41mod version of maa2

There is also 0.42+ mod
http://pastebin.com/F0GLtrx5 I guess it's made specially for Avisynth+ however 0.41mod work fine for me too.
UPDATE2:
@Overdrive80 can you please check if those mods works for you with Avisynth 2.6 ?
