March 2025 performance summary for lab-cosmo/atomistic-cookbook: Focused on documenting reliability and user experience. Completed targeted fix to the Pet-Mad Recipe Documentation: broken link corrected to point to the correct resource. The change improves usability for external references, reduces potential confusion, and supports smoother onboarding and usage of the cookbook.

February 2025 monthly summary: Delivered cross-repo improvements focused on release reliability, stability, and accessibility. Implemented automated release workflow with changelog and standardized notes for v2025.x in metatrain, enabling faster, traceable releases. Stabilized core ML components by moving GAP, PET, and SOAP-BPNN to a stable location, improving import reliability and user experience. Drove a multi-repo release cadence across the Metatensor ecosystem (metatensor-torch 0.7.1–0.7.3, metatensor-core 0.1.12, metatensor-operations 0.3.2 with a bug fix) and updated wheels to align with Python 3.13. Introduced NanoPET architecture with a quickstart to broaden accessibility for experimentation. Modernized CI/CD and documentation: updated for Python 3.13 and ASE 3.23 compatibility, cleaned CI config, and added branding assets (logo) to docs, plus a practical flexible water models example in lab-cosmo/atomistic-cookbook to boost cookbook utility.

2025-01 Monthly Summary: This sprint delivered automation, UX improvements, reliability enhancements, and a modernized release workflow across three repositories.
