Original Changelog¶

This is the original changelog from kbarbary/sep, copied here for posterity.

v1.2.1 (1 June 2022)¶

Changed numpy.float and numpy.int types for deprecations in numpy 1.20 (#96).
Make it possible to safely invoke C library from multiple threads on independent inputs.

Global config functions such as set_sub_object_limit() and set_extract_pixstack() still configure global params (once for all threads), while other functions will retain their data in thread-local storages, so they can be invoked from multiple threads as long as they work on independent structures.

Library compilation will now require a C11 compatible compiler, which should be nowadays available on all supported platforms.
Mark some pointer parameters with const *. This is a backward-compatible change, but makes it easier to extract constants that can be safely shared between multiple threads and/or invocations.

Same as v1.1.0 but with wheels built and uploaded to PyPI. Please report if you have problems with wheels.

Add segmentation masking to the photometry and kron/auto functions (#69).
Add functions sep.set_sub_object_limit(limit) and sep.get_sub_object_limit() for modifying and retrieving the sub-object deblending limit. Previously this parameter was hard-coded to 1024. 1024 is now the default value.
This and future versions are now Python 3 only. Python 2 is no longer supported.
Modernize setup.py with pyproject.toml

Fix double-free bug in sep_extract() arising when an error status occurs and convolution is on. (#56)
Work around numpy dependency in setup. (#59)

Fix makefile so that make install works on OS X for the C library. Python module and C code are unchanged.

Fix bug when using masked filter and noise array where objects with member pixels at end of image (maximum y coordinate) were erroneously missed.

New, more coherent C API. This change should be transparent to users of the Python module.
Add variance uncertainty parameters errx2, erry2 and errxy to output of sep.extract().
Add a minimum sigma to sep.winpos() to match Source Extractor behavior.
Fix use of boolean masks in sep.kron_radius(). Formerly, using a boolean mask resulted in nonsense results.
Fix segfault in Background.back() when box size is same as image size.
Fix bug in creating long error messages on Python 3.

Adds OS X and Windows support.

Bugfix release for problem in setup.py in packaged code.

sep.extract() now uses a more correct matched filter algorithm in the presence of a noise array, rather than simple convolution. The conv keyword has been changed to filter_kernel to reflect this, and a filter_type keyword has been added to allow selecting the old behavior of simple convolution.
sep.extract() now accepts a mask keyword argument.
sep.extract() can now return a segmentation map.
Special methods added to allow data - bkg and np.array(bkg) where bkg is a Background object.

Bugfix release, fixing error estimate in sep.sum_circle and sep.sum_ellipse when bkgann keyword argument is given.

[breaking change] theta field in extract() output is now in radians rather than degrees, for compatibility with new ellipse aperture functions.
[deprecation] Change mask_ellipse() parameters from ellipse coefficients to ellipse axes and position angle, to match aperture functions. (Old behavior still works as well.)
[deprecation] Change apercirc() to sum_circle(), to match new aperture functions. (Old name, apercirc(), still works.)
Add sum_circann(), sum_ellipse(), sum_ellipann(), kron_radius(), ellipse_coeffs(), ellipse_axes() functions.
Exact mode aperture photometery in all functions, with subpix=0.
Enable variable thresholding in sep.extract. [#11]
Fix bug in background masking. This bug impacted masking in all functions that used masking. Also affected C library.
More detail in error messages coming from within the C library. More helpful error message for non-native byteorder arrays.
Add ability to change pixel stack size used in extract(), with set_extract_pixstack() function

This is the first official release.
