Im not sure what more we can actually do to speed things up. The mods needed for the updated DW 20 pack were only finished a couple of days ago. The mods that I want for the new pack I am working on are not finished yet. We cannot update the old packs because some critical mods like Thaumcraft 3 were not updated and other critical mods like Thermal Expansion have not been updated yet.
Any chance of the configs being maintained in a public repository (i'm assuming you've got them in git or similar and that you've had them more or less ready for quite a while) so people can snag them and roll their own installs until the packs arrive?
Thanks for the awesome work you're doing!
