1. the "join" command has been dropped.
2. the sub menu "undo" when you are in offset command is also non existent.
3. the insert raster image still is pixelated although is much improved from the 2011 version.

In fact, the official release of ZWCAD+ 2012 was already published on July 16th, which is better than Beta version.
And there will soon be a Hotfix update coming in September. You may be interested to pay attention to.
