Thanks to all of you that have tested the snapshots and helped me eliminate embarrassing bugs.
It's summer. During July, I will be away from my computer from time to time, and cannot immediately respond to bug reports.
Enjoy!

- Fixed Tweak drag Normal. (Thanks to Fonte Boa). [optigon]
- Moving or duplicating a light in body mode would cause
a crash on the next attempt to select anything.
(Thanks to extrudeface.) [bjorng]
- Marquee selection would selected locked vertices or edges.
(Thanks to ycarry.) [bjorng]
- Select|Similar is now faster if the initial selection
contains elements that are similar to each other.
(Thanks to Ran13.) [bjorng]
- The Wavefront (OBJ) exporter now tries to minimize
the number of smoothing groups. (Thanks to Ran13.) [bjorng]
- Fixed loading models when in smooth-preview mode.
Reported by Ran13. [dgud]
- There is a major internal change in how vertex attributes
(i.e. vertex colors and UV coordinates that are associated with
a vertex in a particular face) are handled.
Vertex attributes used to be stored in the edge table (with
two words per edge always reserved for vertex attributes)
and each vertex could have EITHER a vertex color or
UV coordinates.
Vertex attributes are now stored by themeselves. Objects
without vertex attributes will consume less memory (two
words per edge less than in previous releases). Each
vertex can now have both a vertex color and UV coordinates.
The wings file format should be completely compatible. If
you load a wings file containing an object with both vertex
colors and UV coordinates into an older release of Wings,
only the UV coordinates will be kept. (If you resave such
a file from an older version of Wings, the vertex colors
will be permanently lost.)
Most commands have not been updated yet to take full
advantage of the new vertex attribute implementation. So
while Ambient Occlusion will preserve existing UV coordinates,
there is no way yet to show vertex colors at the same time
as textures.
You can use the commands "Material Mode" and "Vertex Color Mode" in
the body mode menu to switch between seeing materials/textures and
vertex colors. (The commands are not new, but there were few
situations in which they were needed in previous releases of Wings.)
In a future release, we will probably eliminate those commands and
extend materials so that you can choose whether vertex colors,
materials/textures, or a mixture of both should be shown.
Performance seems to be about the same if there are no
vertex attributes, but somewhat slower for models with
vertex attributes.
For developers: Plug-ins using #edge.a and #edge.b will not
compile. Instead use the new wings_va module that provides an API
to the vertex attributes. I have tried to comment each
exported function in the API. [bjorng]
