Changelog included below:

New Features

• Added a .replicate() method to Potential classes to enable copying
  potential objects but modifying some parameter values.

• Added a new potential class MN3ExponentialDiskPotential based on Smith et
  al. (2015): an approximation of the potential generated by a double
  exponential disk using a sum of three Miyamoto-Nagai disks.

• The Orbit.estimate_period() method now returns period estimates in all
  phase-space components instead of just the radial period.

• Added a store_all flag to the integrators to control whether to save
  phase-space information for all timesteps or only the final timestep.

• Added a plot_rotation_curve() method to all potential objects to make a 1D plot
  of the circular velocity curve.

• Added a new potential for representing multipole expansions MultipolePotential.

• Added a new potential CylSplinePotential for flexible representation of
  axisymmetric potentials by allowing passing in grids of potential values
  evaluated grids of R, z values (like the CylSpline potential in Agama).

• Added a show_time flag to Orbit.animate() to control whether to show the
  current timestep.

• Changed Orbit.animate() to allow for different marker_style and
  segment_style options for individual orbits by passing a list of dicts instead
  of just a dict.

• Added an experimental new class SCFInterpolatedPotential that accepts a time
  series of coefficients and interpolates the coefficient values to any evaluation time.

Bug fixes

• Fixed a bug where the NFWPotential energy was nan when evaluating at the
  origin, and added tests for all potentials to check for a finite value of the
  potential at the origin (when expected).

• Fixed a bug in NFWPotential.from_M200_c() where the incorrect scale radius
  was computed (Cython does not always use Python 3 division rules for dividing
  integers!).

• Fixed a bug in the (C-level/internal) estimation of the 2nd derivative of the
  potential, used to generate mock streams, that affects non-conservative force
  fields.

API changes

• The Orbit.estimate_period() method now returns period estimates in all
  phase-space components instead of just the radial period.
