Changed

This version ports support for PSD cones from the Julia version to Rust, with internal supporting modifications to both versions to keep implementations synchronized.

Rust specific changes

• Package implements a variety of dense linear algebra functions using BLAS/LAPACK in support of the PSD cone implementation. Provides various build options for using different BLAS/LAPACK external libraries.

• Python interface makes direct access to SciPy BLAS/LAPACK internal function pointers so that no external library linking is required for distribution via PyPI.

• Constraint reduction for inequalities with infinite RHS #15

• adds vector operation chaining

• add CscMatrix::check_format

• resolve some clippy::pedantic warnings

• fix equilibrations

• Internal fixes relating to initialization of iterates in symmetric cone problems.
• Numerical stability improvements for second order cone constraints.
• Modification of the internal calls to the Rust qdldl to allow for direct assignment of parameters in AMD ordering.
• Added release of binaries for arm64 Linux.
• Fixes to python interface for status checking and versioning.
• Additional unit tests.

• Implements support for exponential and power cones
• Numerical stability improvements
• various bug fixes

First stable release.

• synchronises most functionality with Julia version
• configures shared user guide site at https://github.com/oxfordcontrol/ClarabelDocs
• working deployment actions for pypi
