=========================
We currently support Python 3.8 through 3.13.
A complete list of all new features and changes is given below.
`Relevant PRs and Issues,
<https://github.com/GalSim-developers/GalSim/milestone/24?closed=1>`_
whose issue numbers are listed below for the relevant items.
New Features
------------
- Added `DoubleZernike.xycoef` to directly access the pupil coefficient array rather than
going through `Zernike`. (1327)
- Added a setter for the `Image.array` property, so ``im.array = rhs`` is equivelent to
``im.array[:] = rhs``. This cannot be used to replace the underlying object, only its
contents. But it avoids some confusing behavior that can happen when doing this operation
in an interactive session (such as Jupyter). (1272, 1329)
- Added an option ``recalc=True`` to `SiliconSensor.accumulate`. In conjunction with
``nrecalc=0`` and ``resume=True``, this allows the user more precise control as to when the
pixel boundaries are recalculated during the accumulation. (1328)
Performance Improvements
------------------------
- Switched to inbuilt operators on lists rather than numpy operators in a few places where
they are faster. (1316)
- Added ``robust=True`` option to `Zernike.__call__`, which is both more accurate and faster
for large Noll indices, but is usually slower for small indices. (1326, 1327)
Bug Fixes
---------
- Fixed an error in the `Spergel` stepk calculation. (1324, 1325)
