qutip/qutip: QuTiP 4.7.1

This is a bugfix release for QuTiP 4.7.X. In addition to the minor fixes listed below, the release adds builds for Python 3.11 and support for packaging 22.0. Features Improve qutip import times by setting logger names explicitly. (#1980 by Pieter Eendebak) Bug Fixes Change floquet_master_equation_rates(...) to use an adaptive number of time steps scaled by the number of sidebands, kmax. (#1961 by Christian Staufenbiel) Change fidelity(A, B) to use the reduced fidelity formula for pure states which is more numerically efficient and accurate. (#1964 by Pierre Guilmin) Change brmesolve to raise an exception when ode integration is not successful. (#1966 by Eric Giguère) Backport fix for IPython helper Bloch._reprsvg from dev.major. Previously the print_figure function returned bytes, but since ipython/ipython#5452 (in 2014) it returns a Unicode string. This fix updates QuTiP's helper to match. (#1970 by Asier Galicia) Fix correlation for case where only the collapse operators are time dependent. (#1979 by Eric Giguère) Fix the hinton visualization method to plot the matrix instead of its transpose. (#2011 by Pierre Guilmin) Fix the hinton visualization method to take into account all the matrix coefficients to set the squares scale, instead of only the diagonal coefficients. (#2012 Pierre Guilmin) Fix parsing of package versions in setup.py to support packaging 22.0. (#2037 by Simon Cross) Add back .qu suffix to objects saved with qsave and loaded with qload. The suffix was accidentally removed in QuTiP 4.7.0. (#2038 by Simon Cross) Add a default max_step to processors. (#2040 by Boxi Li) Documentation Add towncrier for managing the changelog. (#1927 by Trent Fridey) Update the version of numpy used to build documentation to 1.22.0. (#1940 via dependabot) Clarify returned objects from bloch_redfield_tensor(). (#1950 by Christian Staufenbiel) Update Floquet Markov solver docs. (#1958 by Christian Staufenbiel) Update the roadmap and ideas to show completed work as of August 2022. (#1967 by Simon Cross) Miscellaneous Return TypeError instead of Exception for type error in sesolve argument. (#1942 by Pieter Eendebak) Add towncrier draft build of changelog to CI tests. (#1946 by Simon Cross) Add Python 3.11 to builds. (#2041 by Simon Cross) Simplify version parsing by using packaging.version.Version. (#2043 by Simon Cross) Update builds to use cibuildwheel 2.11, and to build with manylinux2014 on Python 3.8 and 3.9, since numpy and SciPy no longer support manylinux2010 on those versions of Python.
