# Changelog

## Version 0.0.1

`triqs_xca` Version 0.0.1 provides a 
sum-of-exponentials based bold hybridization 
expansion solver for quantum impurity problems.

This is the initial release for this project, 
with a diagram evaluation implemented using dense linear algebra 
in the local Hilbert space by Z. Huang and J. Kaye.

## Version 0.1.0

`triqs_xca` Version 0.1.0 is a major reimplementation of the diagram evaluation 
exploiting local atomic symmetries by F. Rilloraza, H. UR. Strand, and J. Kaye.

**Note:** The solver API has changed since v0.0.1, see the API documentation.
