Some of you probably heard about it, but lets make it as official announement in here.
Current version (v2.2.0) has been released almost a month ago. I was working hard on preparing Infitech Reloaded, but since GT6 will take probably long time to be in playable state I will be pushing the massive changes from Infitech Reloaded into Infitech 2. This will not include GT6 and honestly I am not even sure if I will be making Infitech with GT6.
I will be making one or two hotfix versions (v2.2.1 and v2.2.2) and then I will be getting the massive update ready. It will be as v3.0.0 and to have the transition for you as smooth as possiible, you will need to restart. You will be able to transfer your current builds, if you will want, with the use of MCEdit or (if you know how) via AE2 Spatial Storage + NEI inventory save feature.
As for what changes will happen in v3, I am not going to tell you all of them, but most notable ones will be removal of some mods (project zulu, biomes o plenty and other not necessary mods), replacing ProjectRed with BluePower and updating ExtrabiomesXL to propper version. Recipes for machines will be extensively changed to the point where you will not be able to really make for example Forestry machines or Steve's Workshop Production tables without touching GT.
Also one change, which we are currently testing, will be complete removal of IC2 cables (yes, no more cheaty wiring).
v3 will also contain RFTools, but it will probably not appear in v3.0.0. There is a lot of stuff I need to do for balancing purposes
If you have any questions or concerns, feel free to ask, and if I will be able I will try to answer them.
Do not ask for ETA on v3. I work on the modpack when I have time, whenever I want.
edit: As for HQM addition. Would love to, but I su*k at writing quests
