kim-api-2.4.2 released: Bug fixes, retries and improved logs

06-Mar-2026

This release adds logging of paths to the API and model libraries to facilitate debugging installation issues, for example in cases where two instances of the API are installed. The kim-api-collections-management utility will now attempt to download items several times before failing due to web errors. Finally, two bugs relating to the new base64-encode method of encoding model parameters were fixed: one that corrupted parameter files on ARM64 only, and one that corrupted citation info printed in LAMMPS on all platforms. See the NEWS file for a more complete summary of changes.

For installation instructions, see the Obtaining KIM Models page.
