.. _changelog: Changelog ========= New in release (0.11.2) [16/04/2025] ------------------------------------ Another minor fix for optional dependency on numba. New in release (0.11.1) [16/04/2025] ------------------------------------ Minor fix for optional dependency on numba. New in release (0.11.0) [16/04/2025] ------------------------------------ This release primarily makes a more minimal dependency set (numpy, scipy, spglib) so that parsers from matador can be used without full database support. To install with the previous default set of dependencies (including e.g., matplotlib, pymongo, numba, etc), use `pip install matador-db[legacy]`. Some older fixes: - Fix numba dep format issue, reported by @MJCliffe. - Run tests for Python 3.11. - Support pymongo v4. New in release (0.10.2) [09/11/2023] ------------------------------------ - Scrape constrained and normal forces separately from CASTEP files by @JordD04 in https://github.com/ml-evs/matador/pull/315 - Refresh some dependencies for the 21st century by @ml-evs in https://github.com/ml-evs/matador/pull/328 New in release (0.10.1) [20/01/2023] ------------------------------------ - Support for continuation and restarting of magres workflows (#306) - Fix for CASTEP scraper to scrape both constrained and unconstrained stress tensors when both are present (#312) New in release (0.10.0) [26/10/2022] ------------------------------------ This release contains many accumulated changes over the course of a year. The library is now primarily in maintenance mode unless new features are contributed by others. - Added a ray-tracing crystal visualisation module based on the `Fresnel library `_. - Refinements of almost all plotting types and styles, as well as making it easier to plot multiple comparative plots on the same figure (e.g., multiple phase diagrams computed with different functionals or from different sources). - Added the :func:`matador.magres` module for referencing NMR calculations against experimental data. - Optimised the CASTEP output reader for long concatenated geometry optimisations. - Minimal integration with `OPTIMADE `_ by being able to download an OPTIMADE structure from a URL as a matador object. - Support for Python 3.10 - Bug fixes for scrapers, densities of states plotting and scattering simulations.
