- Update to 0.16.0
* Added an option to to_fits_sip() to be able to specify the
reference point (crpix) of the FITS WCS. [#337]
* Added support for providing custom range of degrees in
to_fits_sip. [#339]
* Bounding_box now works with tuple of Quantities. [#331]
* Fix a formula for estimating crpix in to_fits_sip() so that
crpix is near the center of the bounding box. [#337]
* Allow sub-pixel sampling of the WCS model when computing SIP
approximation in to_fits_sip(). [#338]
* Fixed a bug in to_fits_sip due to which inv_degree was
ignored. [#339]
- 0.15.0 changelog
* Added insert_frame method to modify the pipeline of a
WCS object. [#299]
* Added to_fits_tab method to generate FITS header and binary
table extension following FITS WCS -TAB convention. [#295]
* Added in_image function for testing whether a point in world
coordinates maps back to the domain of definition of the
forward transformation. [#322]
* Implemented iterative inverse for imaging WCS. [#324]
- 0.14.0 changelog
* Updated versions of schemas for gwcs objects based on
latest versions of transform schemas in asdf-standard.
[#307]
* Added a wcs.Step class to allow serialization to ASDF to
use references. [#317]
* WCS.pipeline now is a list of Step instances instead of
a (frame, transform) tuple. Use WCS.pipeline.transform and
WCS.pipeline.frame to access them. [#319]
* Fix a bug in polygon fill for zero-width bounding boxes.
[#293]
* Add an optional parameter input_frame to
``wcstools.wcs_from_fiducial`. [#312]
