This changelog is relative to the last released version, not the last prerelease!
Additions:
- Ported the power adaptor
 
Improvements:
- The debugger item can now be used in survival to view the F3 debug info on buildcraft blocks (previously this required creative mode)
 - The guide book now has a search bar.
 - Guide book entries can be any object, rather than just item stacks.
 - You can now specify "source" and "type" for changing the type.
 - Currently triggers and actions are the only additions. The type is "buildcraft:statement", and the source is a registry name of a statement (trigger or action)
 - Unfortunately the only way of finding out a statement's ID is via the source code. Woops.
 - Added the "has work" capability (and implicitly the has work trigger) to the distiller.
 - The autoworkbench now shows its filters per slot, and distributes the filters evenly so that the most number of crafting operations can occur
 - For example, when crafting a dispenser (which needs 8 cobblestone, 1 bow and 1 redstone) this will filter 1 slot for cobblestone, 1 for redstone, and 8 for bows as bows cannot stack.
 - Filtered inventories no longer loose the item when loading from disk if the item does not match the filter.
 
Bug fixes:
- Fix torches being placable on pipes (without any pluggables that they could rest on)
 - Fix fluid tanks sometimes leaving a visible gap between the above and below tanks.
 - [#3977] The filtered buffer doesn't work properly with inventory level triggers.
 - [#3989] The Auto Workbench accepts items not used in its recipe.
