LiquidUU: Did not load ThermalExpansion integration: java.lang.reflect.InvocationTargetException
Hah, somebody finally noticed! I have the fix for that in version control (the TE API changed, for the better), but I didn't think it was worth pushing another package out, as much as I've been wanting an excuse for a version 0.7.10. Nothing will break too severely when the TE API doesn't load, it's just that the liquid transposer will return an empty cell for every UUM turned into liquid UU. The new TE API lets me specify that UUM turns into liquid UU without any return, which is better than the old API had, but again, this isn't something I'm particularly worried about.
What I am interested in, however, is Minecraft 1.4.6... mostly because RedPower. I've noticed the link to the Jenkins that's been (according to Kane Hart) published on IRC in a couple of places, and used build 167 to compile against, as well as a custom Buildcraft that I made out of the almost latest github source. So you can now try your hand at LiquidUU v0.7.10-experimental (the Buildcraft I used is also linked) and play with LiquidUU in RedPower. However, note that due to lack of Forestry and Thermal Expansion, the two integrations are excluded from this build (otherwise I couldn't have built it). Once I can put those back in, I'll be happy calling this a 0.7.10 release.
Edit: By the way, don't be surprised if you crash if an RP fluid pipe passes next to an accelerator -- apparently, Eloraam is keeping me on my toes and passing in a null liquid stack. I've updated the package, now that I've accounted for my silly assumption, so redownload and you should get the fixed version. The unfortunate consequence of the way RP does this is that accelerators won't connect to fluid pipes (rather, the other way around). I may change things up before the final 0.7.10 release.
