I've seen in his planned features that in order to update to the next version of any pack containing Gregtech you have to build an update module and companamacerelectrocentriextracinilate it in a companamacerelextrocentriextainizer.
To make the update module, you need 3 supercompressed iridium plates (9 iridium plates makes a compressed iridium plate, 9 compressed iridium plates makes a supercompressed iridium plate), 2 sodamnfuckincomplicated machine circuit truncated blocks, (which among other things needs 6 supercompressed uu-matter blocks, which are compressed in an industrial commercial alienatic overcomplicated compressor) 2 netheressence platium+chrome whyareyoumakingthis upgrades (1 super platinum ingot block, 1 supercompressed chrome ingot block, 7 nether stars make one) and 2 blocks of ultraenriched supernutricious omega dirt. Of course, to make the companamacerelextrocentriextainizer is another forum and wiki on it's own.
