1.1.0 (2020-05-20)

Python compatibility

  • Added Python 3.8 compatibility (#1).
  • Added Python 2.6 compatibility + circle-ci job, documentation amended, code fixed to be compatible with Python 2.6 (#6).
  • Removed tox.ini reference to Python 3.3 builds.

Minor changes

1.0.0 (2020-05-05)

Data updates

Data files were downloaded on 2020-05-05.

  • Updated deltat.data data file.
  • Updated Leap_Second.dat data file.
  • All expiration data items are up-to-date as of 2020-05-05.

Library Runtime Enhancements

  • Added expiration_limit argument for get_skyfield_data_path function. Enables to shift the expiration date limit by "n" days.

Downloader enhancement

  • USNO file serving host has changed. Pointing now at ftp://cddis.nasa.gov/products/iers/ for deltat.* files.

Minor changes

  • Changes in Python setup.cfg classifiers.

0.1.0 (2019-10-04)

Library Runtime Enhancements

  • Dropped compatibility with Python 3.3 and 3.4, as skyfield did.
  • Generate a catalog of the expiration dates for files.
  • Detect when a file has expired and raise a UserWarning.

Downloader Enhancements

  • Added a --check-only argument to download.py to display the expiration dates of the files currently on disk.
  • Enable computation of the expiration date of the BSP file(s) on disk (requires to install the local repository using the [dev] option / See README for more information).
  • Warn user when there's a download error. Expiration date file won't be modified if at least one of the downloads has failed.

Other Improvements

  • Added basic tests for the get_skyfield_data_path function using tox.
  • Added automated tests through Travis CI.
  • Add Travis CI badge on README.
  • Added a test to check if the current files are about to expire (45 days from now). Travis CI would run a monthly job and eventually report when it has failed, so actions can be done to refresh the files and "unbreak" the library.

0.0.2 (2019-08-23)

  • Document the "Advanced" usage, with the expire option for the Loader.
  • Ensure it's Python 2 compatible, since skyfield is compatible with Python 2.6/2.7.

0.0.1 (2019-07-29)

Initial release

  • This project includes minimal data files required by the Python Skyfield library: de421.bsp, deltat.data, deltat.preds and Leap_Second.dat,
  • It provides a small Python script to download the files from their respective source,
  • This script eventually checks if some of the files are expired and skips them (by default),
  • Usage documentation is included in the README.md file.
  • This project code is released under the terms of the MIT License.
