Full Changelog: 1.1.6...1.1.7

Bug fixes:

• Fix caching mechanism of NamedGeneric
• Fix pickling of parametrised classes

New features:

• Unpickling is now backward compatible: pickled diagrams from DisCoPy v0.6 can be unpickled into the current version.
• Tensor is now parametrised by the dtype.
• A hypergraph equality context manager has been.
• Discard has been defined on Markov categories
• Tensor.copy has been added
• The term "polygynous" has been changed to "left monogamous"

Bug fixes:

• Missing qiskit-aer import has been added
• Missing Sum classes has been added to markov
• Broken links in QNLP tutorial has been fixed
• Ribbon rotation has been fixed
• Matrix.swap has been fixed

Notable updates in the documentation:

• Examples from arXiv:2205.05190 has been added into docs/notebooks/examples.ipynb

Fix PennyLane Sympy substitution

• Now the convention of the density matrix is the same as DisCoPy 1: U @ U*
• The documentation has been fixed.
• Serialisation has been fixed. The new recommendation is to just pickle.dump circuits, and soon, we'll implement their loading into DisCoPy 1

• Revert symmetric diagram hashing and equality back to old behaviour, see PR #179
• Fix flake8 coding style #178

Fixes:

• Fix jax support for traced objects (see #177)
