I just updated to from 1.0 version 1.1 and I now notice that my
billboards are no longer transparent around the outside edges of the
quads that the textures are mapped to. What do I have to do to make them
transparent again?

1.0 used AlphaFunc enable for all bins, both transparent and opaque.

1.1 only enable AlphaFunc for transparent bins (ones sorted back to front).

So if you are seeing a difference then your transparent billboards
arn't being placed in the transparent bin.  You have two options,
attach an AlphaFunc to them explictly, or just do a
stateset->setRenderBinHint(TRANSPARENT_BIN) on them, or just apply
AlphaFunc to every thing.

The reason for the change is to ensure the OSG uses the state set up
recommended by graphics card manufactureres for tacking advatnage of
depth earth testing.
