[gdal-dev] Misc. subjects : OSGeo Vienna code sprint, release plans, GDAL 2.0

[Dmitriy Baryshnikov]

Hi Even,

I plan to participate in code sprint too and work on GDAL.
In addition to the mentioned tasks I would like to discuss some politics 
and direction to add new functionality to GDAL.

Best regards,
     Dmitry
