 * Adds a new module, `thewalrus.random`, to generate random unitary, symplectic and covariance matrices. [#169](https://github.com/XanaduAI/thewalrus/pull/169)
 
-* Adds new functions `normal_ordered_expectation`, ` photon_number_expectation` and `photon_number_squared_expectation` in `thewalrus.quantum` to calculate expectation values of products of normal ordered expressions and number operators and their squares.

 * Solves the issue with `quantum` and `samples` not being rendered in the documentation or the TOC. [#173](https://github.com/XanaduAI/thewalrus/pull/173)

 ### Breaking changes
 
 * The functions in `thewalrus.fock_gradients` are now separated into functions for the gradients and the gates. Moreover, they are renamed, for instance `Dgate` becomes `displacement` and its gradient is now `grad_displacement`. [#164](https://github.com/XanaduAI/thewalrus/pull/164/files)
