Release 9.0

New features

• Optimized many parts of the code, resulting in significant performance gains (in some cases, well beyond an order of magnitude)
• Improved the documentation, in particular adding a new chapter on performance tuning, and hyperlinks to namelist option definitions
• Extended the MESA interface to support tidal response calculations
• Added the following choices for the outer_bound option:
  • 'ZERO_R'
  • 'ZERO_H'
• Added a new 'ROWPP' choice for the matrix_solver option
• Added the following output items:
  • chi
  • n_iter
• Added a new 'FILE' choice for the nad_search option
• Added a new 'ADHOC' choice for the lambda_method option

Changed Functionality

• Renamed the following options:
  • matrix_type → ad_matrix_solver (adiabatic), nad_matrix_solver (non-adiabatic)
  • r_root_solver → real_root_solver
  • c_root_solver → cmplx_root_solver
• Renamed the following choices for the ad_matrix_solver and
  nad_matrix_solver options:
  • 'BAND' → 'BANDED'
  • 'BLOCK' → 'CYCLIC'
• Removed the coriolis_method, complex_lambda and rossby options
  from the &rot namelist group. This functionality is now implemented through the lambda_method and complex_lambda options of the &osc namelist group.
• Terminal output now reports the id of modes found
• Alternative variable sets (accessed through the variables_set option) are now directly implemented using SymPy, rather than via numerical transformations
• Added new test suite calculations for tides
• The code now requires a recent release (26.3.2 or later) of the MESA SDK to build

Bug fixes

• Fixed documentation for the 'GAMMA' outer boundary condition choice (now 'GAMMA1' and 'GAMMA2')
