Release notes

Highlights

• ✅ Various additions, improvements to the pandapower converter (e.g., transformers and asymmetric conversions).
• ✅ Various additions, improvements to the Vision converter (e.g., transformer tap regulator).
• ✅ Extended support to provide extra info.
• 💥 Multiple bug fixes.
• 🚀 Added support for pandapower 3 and Vision 9.7 and 9.8.
• 🚀 Improvements and fixes to documentation.
• 🎉 Various improvements to the internal implementation.
• 🎉 The licenses of source and data files were updated.

Dropped functionality

• The std_types input argument was removed from the pandapower converter. The std types deduction now happens automatically. Migration can be done by removing the input argument from the object creation. Note that this change was done more than two years before this version bump in version v1.2.5, so this change will not affect any users that use a recent PGM-IO version. See also Remove PP std types #151.

Dropped Platform/Runtime Support

As agreed on during the last Power Grid Model meet-up and as reflected in the Release Strategy, support for the following Python versions were dropped. Please ensure your environment meets the new minimum requirements.

• Python 3.8 support (see also this announcement).
• Python 3.9 support (see also this announcement).
• Python 3.10 support (see also this announcement).

Please refer to our Release Strategy for details.

Should we add "Cleaning of the PR page" to the checklist? Not necessary, but definitely something nice to add.
