Full Changelog: v1.9.0...v1.9.1

Version 1.9.0

This is version v1.9.0, which contains the following major improvements:

• Added a method to Orbit instances to compute and plot surfaces of section: Orbit.SOS and Orbit.plotSOS. This method uses a custom integration routine that exactly resolves surface crossings and applies to most force fields.
• Also added a brute-force method to compute and plot surfaces of section for use with force fields for which the above method does not work (e.g., in rotating frames)
• Added a method, dMdE, to calculate the differential energy distribution of spherical distribution functions
• Added general support for DissipativeForce instances in 2D and implemented NonInertialFrameForce in 2D

as well as minor bug fixes and minor improvements to the code and to galpy's development workflow.
