Release 20.11

• The aprox19 + NSE network was ported to C++ (#362)

• The simplified-SDC code path was ported to C++ (#389)

Release 20.10

• An option to use NSE instead of integrating the reaction
  network has been added to the aprox19 network. (#332)

• The BS integrator no longer supports simplified-SDC (#393)

• The triple_alpha_plus_cago network switch to using binding
  energies in MeV, consistent with the aprox nets (#354)

Release 20.09

• Unit tests now write a job_info file (#383)

• A new single-zone EOS test routine was created as unit_test/eos_cell
  (#382)

• The gamma_law eos (not gamma_law_general) now fills the sound speed,
  entropy, and derivatives for more inputs (#374)

• The rprox network now has screening (#377)

• The NETWORK_PROPERTIES file was split to put the number of
  auxiliary species into its own file, NAUX_NETWORK. This allows
  us to put if-logic into the file to choose the number of
  auxiliary quantities based on make setting (like USE_NSE). (#370)

Release 20.08

• Several of the unit tests had separate C++ and Fortran
  implementions. These have been unified (#343, #344, #345)

• The VBDF integrator was removed (#348)

• VODE can now reject an internal timestep that has any abundance
  change by more than a factor of 2, or an abundance < 0 or > 1,
  as well as timesteps where the temperature ends up negative. (#350)

Microphysics 20.07

20.07

• The "master" branch has been renamed "main" (#333)

• NETWORK_PROPERTIES now includes the number of Aux quantities (#330)

Microphysics 20.06

20.06

• For integration with simplified SDC, we now interpret atol_spec
  as an absolute tolerance on X alone instead of (rho X) (#311)

• burn_cell can now use the C++ burner if compiled with
  USE_CXX_REACTIONS=TRUE and run with do_cxx = 1. (#313)

• The original burn_cell (which used the F90 BoxLib build system)
  is removed and replaced with burn_cell_C (which uses the newer
  build system). (#316)

• The analytic Jacobian with simplified SDC now is written in terms
  of the conserved fluid state and works for a wide range of
  problems (#228)

Microphysics 20.05

20.05

• We now have an option for using sparse storage for aprox13 in C++
  (#307)

• iso7 and aprox13 are now available as a C++ network (#303, 305)

• species names are available as an enum in network_properties.H (#304)

• The screening on O16+O16 in iso7 was fixed (#302)

• The VODE integrator is now available in C++ (#299)

Microphysics 20.04.1

Microphysics 20.04.1

Microphysics 20.04

20.04

• The wion network property was removed (#294)

• There are new unit tests for the screening and aprox rates
  modules (both C++ and Fortran interfaces).

• The screening routines were ported to C++ (#290) and the screenz
  routine was removed in favor of screen5 (#293)

• a new method, is_input_valid, was added to all EOSes (both C++
  and Fortran interfaces) that can be used to query whether an EOS
  supports a particular input mode (e.g. eos_input_rp). (#291)

• The aprox rates used with iso7, aprox13, aprox19, and aprox21
  have been converted to C++ (#288)

• We've rewritten the VODE integrator to remove all "go to"
  statements (#275, 276, 278, 280, 281, 282, 283, 284, 285, 286,
  287)

• We removed the ability to have nspec_evolve < nspec. This
  feature was not widely used and greatly complicated the code
  paths.(#279)

Microphysics 20.03

20.03

• The nuclei information for both Fortran and C++ is now
  automatically generated from a network inputs file at compile
  time. As part of this change, 1/A is precomputed and stored as a
  constant (#253, 258).

• The license for StarKiller Microphyscs was made explicit and
  a license.txt file was added (#267)

• A framework for pure C++ EOSes has been created and a pure C++
  unit test, test_eos_C, is available to test these. (#246) The
  following EOSes have been ported to C++: ztwd (#268), multigamma
  (#265), polytrope (#264), gamma_law (#263), helmholtz (#262),
  gamma_law_general (#246), rad_power_law (#269), breakout (#270)

• The GPackage.mak files that were a remnant of the old
  BoxLib F90 build system have been removed. They were
  not maintained. (#212).

• All of the interface files have been collected together
  in the interfaces/ dir. (#240)

• The network C++ headers have been renamed network_properties.H
  and the nuclei information (aion and zion) have been
  added. (#244)
