*rolls eyes* Yes, yes. Obviously, this is all just a vast conspirancy to somehow force people to play a certain way... *sigh* For a community that claims to abhor drama, people really like to conjure it from thin air.
The reasons for the name change are simple: Numerous bugs have been occuring since MFR introduced its own (compatible) biofuel. The liquid code in Forestry was written at a time when such a thing as the liquid dictionary did not exist. For that reason most recipe handling is hardcoded to actual item ids and does not use the liquid dictionary. I thought I had squashed those bugs in 2.2.0.1, but turns out I still missed some. So instead of playing "whack-a-bug" for the next 10 releases, I am simply changing the internal name of the liquid. No conflicts with MFR anymore - which means people can actually run Forestry and MFR alongside instead of having to choose one or the other because of $crashbugoftheday. In the meantime I can sort out the liquid dictionary issues at my own pace.
It's not like there is any real reason to have MFR and Forestry produce the exact same liquid. If you are using MFR, you'll feed its biofuel into its bio generator and if you are using Forestry you are dumping ethanol into Forestry's bio generator for EU or straight into combustion engines. Both liquids burn in RC boilers at the same rate. And it's not as if "ethanol" magically isn't added to the liquid dictionary.
So... could people please kindly stop freaking out over a simple name change which will prevent future bugs and actually make MFR and Forestry run more smoothly alongside? But I suppose $drama is more fun...
