v30.0.0 (2026-01-15)#

Dropped support for Python 3.10.

New features#

  • Modified the file readers (including command-line tooling) to support URIs as well as local files. This can be used to read headers from S3 buckets or HTTPS servers. (DM-41256)

  • Added two new translated properties:

    • exposure_time_requested is the requested exposure time and exposure_time is now defined to be the actual exposure time. The default value for an older translator is for the two values to be the same.

    • altaz_end now contains the telescope position at the end of the observation. If a translator has not been updated to support this property the default value is None. (DM-50382)

Miscellaneous Changes#

  • Added a default clipping of the Alt/Az values, which can be overridden by translators. (DM-50167)

v29.0.0 (2025-04-16)#

Dropped support for Python 3.9.

New features#

  • Added support for entry points to be declared by packages providing their own metadata translators. Use astrometadata --list-plugins to list all registered translators. Given the high overheads that can be encountered during the importing of translators, plugins have to be requested explicitly by label rather than preemptively loading all plugins. (DM-47972)

Miscellaneous Changes#

  • Improved the robustness of table mode output when there is a translation failure. (DM-46970)

v28.0.0 (2025-01-24)#

Miscellaneous Changes#

  • Improved robustness of table output when there are translation failures. (DM-46797)

  • Improved some DECam translations. (DM-46014)

  • Improved robustness of tests when the network connection fails. (DM-44651)

v27.0.0 (2024-06-25)#

New features#

  • Added new property, can_see_sky to report whether the observation can see sky photons or not. The default implementation tries to infer the answer from the observation types. (DM-43103)

Miscellaneous Changes#

  • Added a helper utility for calculating the observing day. (DM-43109)

  • Added support for observing_day and observing_day_offset properties. The default implementaiton assumes that the observing day is the UTC day. (DM-42636)

v26.0.0 (2023-12-14)#

Drop support for Python 3.8.

Miscellaneous Changes#

  • The baseline FITS metadata translator has been modified to prefer DATE-BEG over DATE-OBS. (DM-39731)

  • Modified the assertObservationInfoFromYaml test helper method to support the ability to check Alt/Az values. (DM-38400)
