0.4.0 (2022-09-07) Please see the full release notes at https://spacepy.github.io/release_notes.html This release marks the end of support and/or fixes for bugs that cannot be reproduced on Python 3. New features The LANLstar module has been rewritten to use numpy to evaluate the neural networks instead of relying on ffnet. The temporary removal of support for this module in SpacePy 0.3.0 has therefore been lifted. VarBundle now supports output to and input from SpaceData objects as well as CDF. Both coordinates backends now provide access to the TEME coordinate system (as used by the SGP4 orbit propagator). Deprecations and removals The _nelems method of Var has been removed; use the public interfacenelems. irbempy get_sysaxes, sph2car and car2sph were deprecated in SpacePy 0.2.2 and have been removed. In place of the latter functions, coordinates.sph2car and coordinates.car2sph should be used. Major bugfixes The installer has been updated to address certain build issues, particularly on Mac. The Mac installation directions have been completely rewritten. pycdf has been updated for Apple Silicon (ARM/M1). pycdf contains a time conversion workaround for versions of the NASA CDF library before 3.8.0.1. The IRBEM backend for coordinate transformations has been updated to correct the specification of transformations through the J2000 and TOD systems. The IRBEM update also traps a singularity at the South pole in the conversion to geodetic (GDZ) coordinates. Dependency requirements LANLstar now uses a numpy-based implementation so neither ffnet or networkx are required to use it. Other changes pycdf no longer warns when defaulting to version 3 CDFs and TIME_TT2000 time type if not specified. The IRBEM library bundled with SpacePy has been updated to reflect recent updates and bugfixes. If you use this software, please cite it using the metadata from this file.
