------------------
*Added*
* freud 3 is now supported (239).
*Fixed*
* :math:`L_z` for 2D boxes is set correctly in both HOOMD 2 and HOOMD 3 (232).
* For mixtures, :math:`g_{ij}` is now calculated using both type *i* and type
*j* as centers. In general, the RDF now uses the standard statistical mechanics
definition, i.e., for an ideal gas :math:`g(r) = 1-1/N` and **not** 1 (246).
*Changed*
* GitHub Actions versions are now current and will be automatically updated
moving forward (240).
