LDraw.org 2011-2 Parts Update
A new update of the LDraw Parts Library has been made available recently. It is the second update of 2011 and contains 786 elements, with a total of 474 new parts.
The All-In-One-Installer (AIOI) will be updated shortly to include these new parts. In the mean time, even if you are doing a completely new installation, including the update is very easyas the update is available as a windows executable, making automatic installation very easy.
