geos (3.5.0-1) has been uploaded to unstable to start the transition.

To deal with the circular dependency the following uploads have also
been made:

 * spatialite (4.3.0-2)
   Drops liblwgeom-dev dependency to temporarily not depend on postgis

 * gdal (1.11.2+dfsg-2)
   Requires libspatialite-dev (>= 4.3.0-2~)

 * postgis (2.1.8+dfsg-3)
   Requires libgdal-dev (>= 1.11.2+dfsg-2~)

After the buildds have completed these builds, the follow uploads will
be made:

 * spatialite (4.3.0-3)
   Reinstates liblwgeom-dev dependency to fix the regression

 * gdal (1.11.2+dfsg-3)
   Requires libspatialite-dev (>= 4.3.0-3~)

 * postgis (2.1.8+dfsg-4)
   Requires libgdal-dev (>= 1.11.2+dfsg-3~)

After that the rest of geos rdeps can be rebuild as usual.

Kind Regards,

Bas
