In April, the Arelle team delivered a series of infrastructure-focused updates, most notably adding support for Python 3.13 across both the platform and iXBRL Viewer.

Arelle 2.37.3 updates include:
– Added support for Python 3.13
– Introduced a new --inlineTarget CLI argument to specify inline target sets (e.g.,
--inlineTarget=DKGAAP)
– Fixed a bug related to formula parameter resolution for iXDS target documents
– Improved support for EBA 4.0, including fixes for loading xBRL-CSV files
– Resolved an issue affecting behavior when running Arelle as a Windows service

The iXBRL Viewer also now supports Python 3.13, ensuring continued alignment with the latest platform infrastructure.

To get involved with future work, please join the Arelle team monthly standup on the fourth Tuesday of each month at 1400 UTC. Please contact us for meeting details.
