Dear Dart CAM users,

We have found and fixed a bug in the cam-fv model_mod.f90. Incorrect values
were being used in model_interpolate which lead to incorrect assimilation
results. As described in the bug report
https://github.com/NCAR/DART/issues/246, people using this code found
immediate, obvious errors in the assimilation. The bug affects cam-fv
assimilations in all versions of DART since March 10th 2020.

The bug has been fixed in the main (default) branch. The bug-fix has also
been added to the Manhattan branch.

We encourage CAM users to upgrade to the latest version of DART. Please
email dart at ucar.edu with any questions.

The DAReS team.
