Posted on Fri 28 March 2025 in News

ANNOUNCE: aGrUM 2.0.0

aGrUM/pyAgrum 2.0.0 is out.

This major update brings several important changes that align with our goals of improving usability, compliance, and consistency. Below are the three main motivations behind this significant upgrade:

1. License Change : MIT+LGPLV3

The first major change in version 2.0.0 is the update to our software license. This change ensures better alignment with modern open-source standards and provides clearer guidelines for usage, distribution, and modification (see here for details).

2. Package Name Update to Follow PEP8

To adhere to Python's PEP8 naming conventions, we have renamed the package from pyAgrum to pyagrum. We are aware that this change may cause some inconvenience, but it is necessary to ensure consistency with Python's style guidelines and improve the overall user experience. The transition to version 2.0.0 is the right time to implement this change, as it allows us to make a clean break and set a solid foundation for future development.

3. Class Renaming: Potential to Tensor

In an effort to make the library more intuitive and reflective of its functionality, we have renamed the Potential class to Tensor. This change better represents the mathematical nature of the class and aligns with common terminology in the field (see here for details).

4. Modular Code Structure

We have reworked the internal structure of the code to make it more modular. This redesign allows for easier extensibility and maintenance in the long term. By breaking down the code into more independent and reusable components, we aim to facilitate future enhancements and possible contributions from the community.
