• A new option, castro.drive_initial_convection was added that
  uses the temperature interpolated from the initial model instead
  of the value on the grid to call the reactions. This helps
  prevent a reactive zone from burning in place before a convective
  velocity field is established to carry off the energy.

• The burn_weights are no longer stored by default in the plotfile.
  Instead, they are now enabled by setting
  castro.store_burn_weights=1. Additionally, they now give a better
  estimate of the cost for the numerical Jacobian (#1946, #1949)

• castro.change_max is now required to be greater than 1.0. To enforce
  a timestep cap but still allow the timestep to decrease, use
  castro.max_dt. (#1976)

• Gravity was modified to introduce parallel plane gravity with a
  point mass by setting the radius of the star by
  castro.point_mass_location_offset and the integer
  castro.point_mass_offset_is_true == 1. By default, both
  parameters are 0.0 and 0, respectively.

• Starting with this release, problem setups written in Fortran are
  no longer supported and will no longer work. Please consult the
  code documentation and example problem setups in Exec/ to understand
  the new problem setup format. If you need help converting a Fortran
  setup to C++, please file an issue. (#1728, #1732)

• Sponge parameters are now only accepted through the inputs file; the
  &sponge namelist in the probin file is no longer read. (#1731)

• Ambient parameters are now only accepted through the inputs file; the
  &ambient namelist in the probin file is no longer read. (#1742)

• The update_sponge_params hook has been removed. (#1716)

• The Fortran problem-specific source file, ext_src_nd.F90, has been
  removed. Problem-specific sources should be implemented in C++ in
  problem_source.H. (#1856)

• Support for the legacy tagging scheme based on probin parameters (denerr,
  tempgrad, etc.) has been removed. These can be replaced with equivalent
  tagging criteria constructed in the inputs file; see the docs or examples
  in Exec/ to see how to use amr.refinement_indicators. (#1834)

• The Fortran set_problem_tags hook has been removed. The C++ replacement
  is problem_tagging() in problem_tagging.H. (#1828)

• The PrescribedGrav functionality has been removed (not replaced with a C++
  implementation). If you want to obtain the same functionality, you can use
  a problem-defined source term (look for problem_source in the documentation)
  and make the appropriate modification for applying it directly to the state
  (e.g. the momentum source term is rho * g). (#1854)

• The custom radiation boundary using lo_bcflag and hi_bcflag coupled with
  an implementation of rbndry has been removed. (#1743)

• We no longer store Reactions_Type in checkpoint files. This means
  that newer versions of Castro will not restart from old version.
