Thermal Expansion thinks that they don't have to update until 1.8 .

Thermal Expansion has updated to 1.7.10.
Mostly because updating to 1.7.2 is pointless as Forge is no longer updating to that version, and most mods are updating to the most recent version, both for Vanilla MC and Forge. You are deciding to yell at Thermal Expansion because they are not updating to 1.7.2. What about Father Toast's Mods(first thing that came to mind) that also did not update to 1.7.2? Why aren't you yelling at them?I am giving this suggestion because thermal expansion said that they will not update to 1.7.2 but to 1.7.10 .
If you're yelling at them because they didn't update to an obsolete version of Minecraft, then you should be yelling at GregTech for not updating to 1.2.5. This part of your argument is stupid and pointless.
