Release notes

This page contains the release notes for Jet.

Release 0.2.3 (development release)

Patches

• The calculation in the function GetPathFlops has been altered so that it is consistent with the way Cotengra and the jet paper computes the FLOPS for a given path.

Improvements

Documentation

• The jet paper reference in the README.md has been updated because it is now published in the Quantum journal.
