- Fixed a bug due to which a warning log message "Failed to align catalog..." would be issued for successful alignments. [84]
- Fixed a bug in creation of WCS image groups with empty catalogs. [84]
- Fixed a bug in ``match2ref`` when it was run in a non-matching mode (``match=None``) dute to which it was impossible to detect the case when reference catalog has a different length from a supposedly matched WCS group catalog. [84]
- Fixed a bug in computation of the bounding polygon of a reference catalog containing only two sources. [84]
- Fixed a bug in ``convex_hull()`` resulting in incorrect type being returned in case of empty input coordinate lists or whne only one point is provided. [84]
- Implemented a more robust estimate of the maximum type supported by ``numpy.linalg.inv``. [82]
- Renamed ``wcsutils.planar_rot_3D`` to ``wcsutils.planar_rot_3d``. [75]
- Renamed ``wcsutils.cartesian2spherical`` to ``wcsutils.cartesian_to_spherical`` and ``wcsutils.spherical2cartesian`` to ``wcsutils.spherical_to_cartesian``. [71]
- Improved "2dhist" algorithm that performs simple catalog pre-alignment used for source matching. [69]
- Changed the default value of the ``searchrad`` parameter in ``matchutils.TPMatch`` to 3. [69]
0.4.5
=====================
- Fixed incorrect pointer type introduced in previous release [67].
