Here comes a minor BuildCraft release, 2.2.11. You shouldn’t have to upgrade except if you are having troubles with server, in particular for migration between your 1.8.1 worlds and your 1.0.0 ones, where a major issue has been fixed. Here’s the changelog:
#25 items can’t be thrown out of obsidian pipes
Items can be thrown out of obsidian pipes again.
#114 bucket “eaten” by stone engine
Stone engine do not remove the bucket anymore.
#116 temporary fix for the refinery
Fuel can’t enter back in the refinery anymore.
#117 can’t import SMP world from 2.2.5
World created with BC before 2.2.6 can now be properly loaded in BuildCraft again
#118 issues with auto-workbench refresh
Fixed a dupe bug (again) in SMP auto-workbench
#119 consider move FillerPattern and FillerRegistry out of the API
Temporary moved FillerPattern and FillerRegistry out of the API since they rely on core. AFAIK, nobody is using these at the moment, but let me know if that causes a problem.
#121 fix potential pipe exception in SMP
Fixed various exceptions in SMP when loading worlds with invalid pipe contents.
The BuildCraft server (s15972928.onlinehome-server.info) is to be updated soon. Enjoy!
