Okay, update time.
0.5 is inching closer and closer. This one is taking a little longer, due to Forestry and Buildcraft talking some significant versions forward. We're testing mods and their interactivity with these .. not to mention Extra Bees and Magic Bees. Once this round of testing is done, I will do another mod update (lots more overnight), and try to get a stable 0.5 out the door.
Oh, and Biomes O Plenty and Natura are working together so they .. well .. work together. Current word from the devs is, a day or two for this to occur.
I am aiming for 0.5 to have a server release as well. It should be noted, we love you to go and try it .. but do NOT plan on using this as a perm world. Anything could change behind the scenes during this beta phase, and you could well end up with a world that just doesn't work with a 'proper' release.
Am sorry that 0.5 is taking longer than we hoped, but seriously, the last thing we want to push out is a pack that we know doesn't work well.
Step by step, inch by inch.
