Each mod release includes the latest version of the manual at that time; thus, the latest version for 1.7.10 should have the same version of the manual as the latest version of 1.8 as they were released at roughly the same time.
There will be at least one more 1.7.10 release that will include the rupees and wallets.
I probably won't be doing any coding over the summer, though, since we had more than 6 months of no sunshine this winter and I'd like to take advantage of it while I can, ya know? Plus the baby and puppy need to get outside and experience the world.

you have to look in both the mob config file and the entity biome group config file. You have to make sure the mobs have a list of biomes they will spawn in.

deliberate change, you just have to be in range and looking at a target to attack with the off hand.
