The recent Pax, and of course the summer ending, or even the summer itself, brought a huge slow in production of both large and minor updates. Mods like IC2 and Redpower lost their original support, as well as PowerCrystals mods, even atomic stryker isint updating too much. Thaumcraft and EE3 are pending updates, with a guarantee on an EE3, possible EE2 update.
Thank you for posting an actual answer. I can see how summer being over could slow down, or stop, mods altogether.
