[osg-users] possible (probable) state leakage in the master

[Robert Osfield]

Hi Nick,

I am working 100% on VSG most of my available work time right now.  On the
OSG side I'll be focused on bug fixes for the 3.6 branch, rather than
pushing development on OSG master.   My recommendation is that you test the
OSG-3.6 branch and see if the problem exists there, if it does create a
small example then I or others can test this and see if there is anything
amiss with your usage or with the OSG.  We can then get a fixed checked
into 3.6 branch.

If there are fixes in 3.6 that warrant a new release I'll look to getting a
3.6.4 stable release before Christmas, will need community support and
testing for this to happen.

Cheers,
Robert.
