New feature release: 13 November 2026

The LAMMPS 13Nov2026 feature release is now available for download on GitHub and in the LAMMPS webserver download area.

This release contains new features and updates that did not make it into the 30Sep2026 stable release and additional ports to the GPU, KOKKOS and OPENMP package. There are also updates for improved performance and faster builds. Our local automated testing hosted at Temple University is significantly improved with those changes as are the test runs on GitHub.

We are currently receiving many bug reports and AI assisted contributions, so new feature releases may be more frequent than in recent years and contain more changes in each release than in previous years.
