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.

Full Changelog: v1.8.2...v1.9.0

Version 1.8.3

Patch release to fix an issue with the Linux wheels (which didn't link to the OpenMP library properly) and the underlying setup.py issue. No new functionality was added.

Version 1.8.2

This is version v1.8.2, which contains the following major improvements:

• actionAngleVertical, an actionAngle class for 1D action-angle calculations
• actionAngleVerticalInverse, an inverse actionAngle class that allows one to go from (x,v) -> (J,theta,Omega) for 1D potentials
• interpSphericalPotential can now be used as the potential in spherical distribution functions
• Orbit.animate3d displays a 3D animation of an integrated orbit

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

Version 1.8.1

This is version v1.8.1, which contains minor bug fixes and (mainly) improvements to galpy's development workflow.

For a full list of changes since v1.8.0, see HISTORY.txt.

Full detailed changelog: 8a8a87f...10cbeec

Version 1.8.0

This is version v1.8.0, with highlights:

• Addition of galpy.df.streamspraydf, a particle-spray technique for generating mock stellar streams
• Updated and added phase-space positions for Milky Way satellite galaxies and globular clusters (from Gaia EDR3 work
• Added a 'Try galpy' interactive session on the documentation's home page powered by new pyodide/emscripten/wasm wheels for galpy.

Version 1.7.2

This is version v1.7.2, which has added functionality and the same high level of testing as v1.7.1. Given that automation has made releasing versions much: easier, trying out releasing a smaller update to more quickly get interesting new functionality and bug fixes to users. Highlights of the new release are:

• Support for fictitious forces in non-inertial reference frames, allowing, for example, the Milky Way's center acceleration due to the influence of the LMC to be taken into account
• Progress bar when integrating multiple orbits at once using tqdm
• Potential methods/functions and Orbit methods rE and LcE to compute the radius and angular momentum of an orbit with energy E

Version 1.7.1

Minor version update whose main purpose is to add a Python 3.10 wheel to the released version. Otherwise almost identical to v1.7.0.

Version 1.7.0

This is version v1.7.0, which has added functionality and the same high level of testing as v1.6.0:
