galpy 1.11.2

Version 1.11.2

on Python PyPI

Revolutionized by the rise of agentic AI, this release contains many new additions, including a major change, and otherwise many bug fixes and dependency/project maintenance.

Major change

• Implement CompositePotential, planarCompositePotential, and linearCompositePotential classes for unified potential combination interface by @Copilot in #794:

  Previously, potentials and forces could be added by creating a list of them and passing it to all functions and methods taking Potential/Force input. In the current release, this list-based combination has been replaced by classes representing combined potentials in 3D, 2D, and 1D. Lists of potentials/forces are currently still allowed in the code, but they are being deprecated and are scheduled for removal in version 1.13.0. But because combined potentials should have been created using addition with + already, unless you were explicitly creating lists, current code should still work (because + now creates instances of the new combined-potential classes). This means that now there is no functional difference between single and combined potentials/forces and combined potentials can be called with methods just like single potentials, e.g., MWPotential2014.vcirc(8*u.kpc) works.
