v1.4.0

1.4.0 - 12/05/2026

Starting with this version, PineAPPL has an official logo!

Added

• added optimize_using in Grid objects of the Python API
• added an actual implementation of pineappl_grid_metadata and
  pineappl_grid_set_metadata in the APIs

Fixed

• fixed fragmentation scale evolution, particularly for the specific case where
  the fragmentation scale is the only scale present
• fixed a bug in the Newton's convergence method by raising the maximum number
  of iteration
• fixed a bug in the implementation of pineappl_channels_add of the Fortran
  API
• Improve detection of convolution function in the CLI

Changed

• raised MSRV to 1.91.0
• raised Rust edition to 2024
• instead of depending on a previous version of the PineAPPL crate, a new crate
  pineappl_v0 is now responsible for loading files with file version v0
• raised dependency on pyo3 to 0.27, which drops support for PyPy 3.9 and 3.10
• renamed the switch --discard-non-matching-scales to
  --discard-non-matching-values, which now also discards momentum fraction
  values unavailable to APPLgrid. Both --discard-non-matching-scales and the
  new --discard-non-matching-momenta are aliases to the new option name to
  guarantee backwards compatibility of the CLI.
