Release 24.01

24.01

• An option for unlimited PPM reconstruction was added (#2670)

• An option allowing for optional passive sources to the conserved
  state was added (#2678)

• A script diag_parser.py was added to allow for easy parsing of
  the global diagnostic files output at runtime (#2666, #2667)

Release 23.12

23.12

• The radiation solver port to C++ has been completed (#2638, #2648)

Castro 23.11

23.11

• Problem GNUmakefiles have been standardized and now allow for the
  problem to be compiled elsewhere (#2640, #2641, #2642, #2643)

• The true-SDC Newton solver has been made more robust and faster
  (#2586, #2602, #2605, #2606)

• Several problems that required the initial model grid spacing to
  be specified in the inputs file now automatically compute it as
  needed, including flame_wave (#2610), convective_flame,
  bubble_convergence, and hse_convergence (#2624), double_bubble,
  gamma_law_bubble, and hse_convergence_general (#2612)

• Outflow boundary conditions for the 4th order solver have been changed
  to no longer use the one-sided stencil (#2607)

• The ca_rad_source hook in Fortran has been removed. The existing
  problem_rad_source() hook in C++ can be used instead. (#2626)

• The compile option USE_AUX_UPDATE has been removed. If you want to
  manually update the auxiliary parameters, you can use an external
  source term or you can use the problem post-timestep hook. (#2614)

• The pressure is now always included in the x-momentum flux in 1-d
  Cartesian, and this fixes an issue at jumps in refinement with the
  pressure gradient (#2468)

• A bug was fixed in the 4th order diffusion operator that was introduced
  when it was originally converted to C++ (#2592)

• The 2nd order Radau integrator had the wrong quadrature weights
  (#2594)

Release 23.10

23.10

• True-SDC no longer evolves density as part of the reaction system
  and now uses the same ODE code path as simplified-SDC. This means
  we don't need our own custom VODE righthand side functions (#2559,
  #2560, #2567, #2578, #2580, #2584)

• The true SDC runtime parameter sdc_solve_for_rhoe has been
  removed. (#2572)

• The true SDC runtime parameters sdc_solver_tol_spec,
  sdc_solver_tol_ener, sdc_solver_atol have been removed.
  Instead the Microphysics integration tolerance parameters should
  be used. (#2571)

• The true SDC runtime parameter sdc_newton_use_analytic_jac has
  been removed. Instead the Microphysics integrator jacobian
  parameter should be used (#2573)

• Time evolution without subcycling on the fine levels, which is enabled via
  the runtime parameter amr.subcycling_mode = "None", has been significantly
  rewritten to improve computational performance for certain cases. When the
  fine levels do not subcycle, the evolution can be done by processing all
  of the hydro updates on the fine level together and then immediately doing
  the flux correction to sync the coarse and fine level fluxes at the
  boundary between levels. This is how many AMR codes that do not subcycle
  are written. Castro now does this when the user chooses not to subcycle.
  The benefit of this approach is most evidence for problems with Poisson
  gravity that use a multigrid solve, as we can significantly reduce the
  number of Poisson solves per step, performing only a single composite
  (multi-level) solve at the new-time simultaneously for all levels. (#2505)

Release 23.07

23.07

• The parameter castro.state_nghost, which allowed State_Type to have ghost
  zones, has been removed. (#2502)

• The additional ghost zone in State_Type, used when radiation is enabled,
  has been removed. The checkpoint version number has been updated to avoid
  restarting from a checkpoint with the wrong number of ghost zones. (#2495)

• The parameter gravity.no_composite was removed (#2483)

• The parameter spherical_star was removed (#2482)

Release 23.06

23.06

• The job_info file now reports the integrator used (#2463)

• 1-d cylindrical geometry was fixed (#2465, #2470)
