infact this is not really a bug, irrespective zero vertex group weights gave overlapping geometry which isn't useful, add an option to set the thickness factor for zero weighted verts.
Enabled by default and also enabled for older filesm so
there should be no regressions.
In some cases it's useful to not use subdivided uvs for multires.
*Removed curve init code in readfile (no more needed since the split broke anyway compatibility with earlier WeightVGroup files…).
*Updated get_ob2ob_distance() code (much simpler – I’m not a matrices’ god!).
*Enhanced a few RNA names (Campbell has others in mind here, though, I think).
* Canvas and brush can be now enabled simultaneously. This way it's possible for two canvases to interact.
* Added basic anti-aliasing support for vertex surfaces.
* 3D-view color preview now works even when there's subsurf modifier after Dynamic Paint in modifier stack.
* Added a new brush option to use proximity from object center.
* Default surface frame range now use scene's start and end values.
* Improved ray checks for volume brushes.
* Added new "non-closed" option for volume brushes. This way it's possible to use planar meshes as "volume" brushes with predefined ray direction.
* New carrot branch splash image by CGEffex.
* Improved brush affection code.
* Lots of smaller improvements.
* Fixed: Weight paint didn't work with particles.
* Fixed: Point cache didn't work for non-wave surfaces anymore since last commit.
Committed changes from previous weeks, biggest changes are:
* Canvas can now have multiple "surfaces" that each can have specific format, type and settings.
* Renewed UI to support this new system.
* Aside from old "image sequence" output format, Dynamic Paint can now work on vertex level as well. Currently vertex paint and displace are supported.
* Integrated vertex level painting with Point Cache.
* Added viewport preview for Point Cache surfaces.
Due to massive amount of changes, old Dynamic Paint saves are no longer supported. Also some features are temporarily missing or may not work properly.

From the patch description:
ValterVB on #blendercoders submitted a long list of missing tooltips in Blender, and I went through the list and added all I knew. After that I crowdsourced the rest by putting a spreadsheet on Google docs and having people fill in the missing ones that I didn't know. So if there's some weird tooltip in there that doesn't make sense, that's why.
Thanks to Wolter, spacetug and others on BlenderArtists for contributing tooltips.
simple modifier, almost like a hook, except it can deform with 2 object source -> target, has option to preserve rotation and use different falloff types.
Coded a new modifier, "Precision UV Interpolation",
that triangulates, subdivides, then uses brecht's mean
value interpolation to interpolate face data.
Textures on ngon faces get interpolated a bit nicer, in
other words (though concave cases, e.g. 'N', don't work very well).
* This is basically a total rewrite of the edge split algorithm. The old one didn't handle tris at all and quads were cut wrong in some cases too with the addition of not handling uv coordinates at all.
* This new algorithm uses a flag system to categorize different splits and the identical but rotated cases in a similar way to how marching cubes indexes different cases.
* It cuts quads and tris and creates proper uv's for the new faces too.
* I also renamed the option to "edge cut" to differentiate if from the edge split modifier and added an option to override a uv-channel in the exploded mesh with particle age as x-coordinate so that the shrapnel can be faded out nicely etc.
