Patch 1.5.5

• Added: 3D prints can be recycled by putting them into 3D printers as material.
• Added: Sign upgrade will add sign text to tablet_use signal.
• Added: Filtering to AE2 item listing callbacks getItemsInNetwork and getCraftables. Filters are tables with the same (basic) keys as converted item stacks, the values being the (exact) filter values.
• Added: Drivers for newer RF energy API interfaces, should make them work with mods only implementing the newer ones.
• Added: Lore entry is now added to item stack information.
• Fixed: Potential memory leak with Microcontrollers (thanks a ton to marcin212).
• Fixed: cat.lua not closing file handles (thanks mpmxyz).
• Fixed: Mod integration for power providing mods being disabled when power usage was disabled.
• Fixed: Potential persistence issues with userdata.
• Fixed: Improved persistence behavior of TCP sockets.
• [MC1.7.10] Fixed: UV mapping for 3D prints.
• [MC1.7.10] Fixed: hopefully fixes crashes with AE2 version rv2-beta-20 and newer.

Edit: Build 11 is a hotfix for a crash in the power distributor tile entity renderer.
