Release v0.9.0 · astropy/reproject

What's Changed

Drop support for Python 3.7.
Infrastructure and packaging updates.
Made many improvements, bug fixes, and significant speed-ups for the adaptive resampling algorithm, reproject_adaptive. These bug fixes may cause changes to the reprojected images, which are typically negligible.Improvements include the addition of a flux-conserving mode, support for a Gaussian filter kernel, a menu of boundary-handling modes, and a center_jacobian flag to trade speed for accuracy with rapidly-varying transformations.
Added a roundtrip_coords argument to reproject_adaptive and reproject_interp. By default, all coordinate transformations are run in both directions to handle some situations where they are ambiguous. This can be disabled by setting roundtrip_coords=False which may offer a significant speed increase.
