v0.4.0

Breaking Changes

• overlapwithpaulisum() now has an extra factor of 2^nqubits to be in line with other overlap functions. scalarproduct() takes its place instead.
• The Y Clifford gate definition had a missing minus sign.
• Removal of some toy functions like commutes() between two symbols.
• The low-level truncation functions are no longer exported

Further Changes

• Many docs clarifications or removals for functions exposed on the docs page
• Addition of functions like + and * between PauliSum and PauliString
• Automatic promotion of types for these operations
• Automatic wrapping of coefficients into PauliFreqTracker when max_sin or max_freq are not Inf.

New Contributors

• @ErikWeiss made their first contribution in #80
