v1.3.0

1.3.0 - 06/12/2025

Added

• added a pineappl_grid_delete_bins method to the C-API

Fixed

• fixed bugs in stopping condition of the Newton iteration method
• fixed a bug in comparing interpolation::Interp objects when one of the
  boundaries is NaN

v1.2.0

1.2.0 - 22/08/2025

Added

• added Grid::repair to repair bugs that survived by writing bugged grids to
  disk, for example #338. The CLI
  offers this functionality via pineappl write --repair and it can also be
  accessed via Python

Fixed

• added a missing implementation for a branch in Grid::merge that was
  triggered when exporting some PineAPPL grids generated from the 'pinejet'
  group
• fixed wrong coupling orders when exporting to APPLgrid. This happened when
  the PineAPPL grid had orders that had any other ordering than 'LO', 'NLO',
  'NNLO'
• fixed a bug that caused exported grids to compare unsuccessfully when the
  convolution functions were proton-anti-proton; APPLgrid doesn't store the
  types of convolution functions, so we simply convert the grid to use only
  proton PDFs

Changed

• the function Grid::evolve now makes use of parallelization to take advantage
  of the number of CPU cores available using the Rayon crate; the number of CPU
  cores to be used can be controlled via the RAYON_NUM_THREADS environment
  variable

v1.1.0

1.1.0 - 08/07/2025

Added

• added a new V3 metadata reader to the pineappl evolve CLI for EKOs
  generated with v0.15.0 or higher
• C API: added new functions pineappl_grid_evolve_info_shape,
  pineappl_grid_evolve_info, and pineappl_grid_evolve to evolve grids
• C API: added pineappl_fktable_optimize to optimize FK Table-like objects
  given an optimization assumption
• added methods Grid::merge_channel_factors and Channel::factor

Fixed

• fixed a bug that caused pineappl export to fail when called with grid
  having non-trivial factors in their channel definitions

v1.0.0

1.0.0 - 10/06/2025

PineAPPL 1.0 is a major rewrite from the previous version, allowing grids to
have an arbitrary number of convolutions in the initial (PDFs with a
factorization scale) and in the final (FFs with a fragmentation scale) state.
This required a change in the file format that is used to write out grids, but
the old file format can still be read with this new version.

Added

• added new method Grid::delete_orders and the corresponding switch
  --delete-orders in the subcommand write of the CLI
• added the switches --xir and --xif, which allow varying the
  renormalization and factorization scales with a custom factor in the
  subcommand convolve
• the CLI now allows the user to mark convolution functions as polarized
  by adding +p to its LHAPDF name, as a fragmentation function by adding
  +f and both by adding +pf or +fp
• added switches --fk-table-fac0 and --fk-table-frg0 to pineappl read to
  read out the squared factorization and fragmentation scales of FK-tables

Changed

• the macro channel! now accepts a channel specification that is of the
  format factor * (pid, ..) + ...
• Python API: dropped top-level Python interface layer
• Python API: renamed lumi to channel in PyO3 Python interface. This
  concerns 1) the argument names of convolute_with_one and similar functions;
  2) the module pineappl.lumi was moved to pineappl.boc; 3) the class
  LumiEntry was renamed to Channel
• Python API: .into() needs to be explicitly called on subgrids when calling
  pineappl.grid.set_subgrid()
• Python API: replaced pineappl.grid.PyPidBasis with
  pineappl.evolution.PidBasis
• Python API: replaced pineappl.grid.PyOperatorSliceInfo with
  pineappl.evolution.OperatorSliceInfo
• Python API: drop all Py prefixes, for instance PyEvolveInfo was renamed
  to EvolveInfo
• by default pineappl plot no longer shows a channel breakdown in the panel
  with absolute PDF predictions. However, this feature can be enabled with via
  a new array added at the start of the script
• raised MSRV to 1.80.1
• changed the order of elements in Grid::fill of the parameter ntuple to
  reflect the ordering of kinematics given to Grid::new
• renamed the following switches of pineappl write: --remap to
  --set-bins, --remap-norm-ignore to --div-bin-norm-dims and
  --remap-norm to --mul-bin-norm. These names should reflect the
  corresponding operations
• renamed the switch --fktable to --fk-table of pineappl read

Removed

• Python API: removed pineappl.grid.Grid.create() and
  pineappl.fk_table.FkTable.from_grid() methods; use the constructors
  of the respective class instead
• removed the constructor Grid::with_subgrid_type
• removed Grid::convolve_subgrid and --subgrid-pull from pineappl plot
  that was using the method. The CLI subgrid-pull plotting routine only ever
  worked for grids with two convolutions
