Full Changelog: https://github.com/astropy/reproject/compare/v0.9...v0.10.0

0.9 - 2022-09-02

• 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.

0.8 - 2021-08-11

• Improve find_optimal_celestial_wcs to accept input data descriptions as
• just array shapes, not necessarily fully populated arrays. This makes it
• possible to solve for the optimal WCS for a set of images that couldn't fit
• into memory all at once, since the actual data aren't needed for optimal WCS
• determination. [#242]
• Fix implementation of hdu_weights in reproject_and_coadd. [#249]

0.7.1 - 2020-05-29

• Fixed compatibility with Astropy 4.1. [#234]
• Updated minimum requirement for SciPy. [#236]

0.7 - 2020-04-02

• Made C extension in overlapArea.c thread-safe by removing global
• variables. [#211]
• Made it possible to control whether to output debugging information
• from overlapArea.c by setting DEBUG_OVERLAP_AREA=1 at build-time. [#211]
• Fix compatibility with astropy v4.0.1. [#227]
• Disable parallelization by default in reproject_exact - this can be
• enabled with parallel=True. [#227]
• Fixed a bug with reproject_exact with parallel=False and
• return_footprint=False, which caused the footprint to be returned
• anyway. [#227]
• The infrastructure of the package has been updated in line with the
• APE 17 roadmap (https://github.com/astropy/astropy-APEs/blob/main/APE17.rst).
• The main changes are that the python setup.py test and
• python setup.py build_docs commands will no longer work. The
• easiest way to replicate these commands is to install the tox
• (https://tox.readthedocs.io) package and run tox -e test and
• tox -e build_docs. It is also possible to run pytest and sphinx
• directly. [#228]

0.6 - 2019-11-01

• Added support for using any WCS that conforms to the WCS API described
• in the Astropy Proposal for Enhancements 14 (APE 14). The
• independent_celestial_slices= argument to reproject_interp has
• been deprecated since it is no longer needed, as transformations are
• automatically done in the most efficient way possible. [#166]
• Include a warning for high resolution images with reproject_exact,
• since if the pixels are <0.05", precision issues can occur. [#200]
• Added a new reproject_and_coadd function for doing mosaicking of
• individual images, and added section in documentation about mosaicking.
• [#186]
• Added a new reproject.adaptive sub-package that implements the DeForest
• (2004) algorithm for reprojection. [#52]
• Fixed a bug that caused 'exact' reprojection results to have numerical
• issues when doing identity transformations. [#190]

0.5.1 - 2019-09-01

• Fixed a bug that caused 'exact' reprojection to fail if one or more of
• the WCSes was oriented such that E and W were flipped. [#188]

0.5 - 2019-06-13

• Improve parse_output_projection to make it so that the output projection
• can be specified as a filename. [#150]
• Fixed a bug that caused HEALPix maps in RING order to not be correctly
• interpreted. [#163]
• Make it possible to specify the output array for reprojection using the
• output_array= keyword argument. [#115]

0.4 - 2018-01-29

• Refactored HEALPix reprojection code to use the astropy-healpix package
• instead of healpy. [#139]
• Added the ability to specify an output array in reproject_interp, which
• permits the use of memory-mapped arrays and therefore provides the capability
• to handle data cubes much larger than memory [#115]
• Fix test 32-bit test failures. [#146]
• Fix an issue with reprojecting images where there are two solutions along
• the line of sight by forcing round-tripping of coordinate conversions [#129]
• Explicitly define default HDU as 0 for normal reprojection and 1 for
• HEALPix reprojection. [#119]
• Added a function to find the optimal WCS for a set of images. [#136, #137]

0.3.2 - 2017-10-22

• Fix a regression that caused certain all-sky images (e.g. the Mellinger Milky
• Way Panorama, http://www.milkywaysky.com) to be reprojected to all NaNs when
• the output WCS was in Mollweide coordinates. [#124]

0.3.1 - 2016-07-07

• Include missing license file in tarball.
• Updated documentation to remove warnings about early versions.

0.3 - 2016-07-06

• Allow users to pass a field= option to reproject_from_healpix
• to access different fields in a HEALPIX file. [#86]
• Significant improvements to performance when the input data is a large
• memory-mapped array. [#105]
• Significant refactoring of interpolating reprojection to improve support for
• n-dimensional arrays, optionally including two celestial axes (in which
• case the coordinate transformation is taken into account). [#96, #102]

0.2 - 2015-10-29

• Fixed a bug that caused reprojection by interpolation to be truncated for
• rectangular output images.

0.1 - 2015-05-08

• Initial Release.
