- Update to 1.8.0
## New Features
### photutils.profiles
* The RadialProfile and CurveOfGrowth radial bins can now be
directly input, which also allows for non-uniform radial
spacing. [#1540]
## Bug Fixes
### photutils.psf
* Fixed an issue with the local model cache in GriddedPSFModel,
significantly improving performance. [#1536]
## API Changes
* Removed the deprecated axes keyword in favor of ax for
consistency with other packages. [#1523]
## photutils.aperture
* Removed the ApertureStats unpack_nddata method. [#1537]
## photutils.profiles
* The API for defining the radial bins for the RadialProfile and
CurveOfGrowth classes was changed. While the new API allows for
more flexibility, unfortunately, it is not
backwards-compatible. [#1540]
## photutils.segmentation
* Removed the deprecated kernel keyword from detect_sources and
deblend_sources. [#1524]
* Deprecated the kernel keyword in SourceCatalog. [#1525]
* Removed the deprecated outline_segments method from
SegmentationImage. [#1526]
* The SourceCatalog kron_params attribute is no longer returned
as a ndarray. It is returned as a tuple. [#1531] (forwarded request 1087844 from bnavigator)
