🚨 Breaking changes

Available Python versions

pypowsybl is now only built and released for python versions between 3.10 and 3.14. Python 3.9 is now longer supported, pypowsybl 1.14.0 will be the last version available for this python version.

RAO parameters

See the migration guide to migrate your RAO parameters to the new structure.

Renaming dangling line to boundary line

The "dangling line" powsybl object has been renamed to "boundary line". Most of the methods/arguments referencing dangling lines have been deprecated for their "boundary line" counterpart.

In the get_injections method, the type column can break since the value DANGLING_LINE is now BOUNDARY_LINE.

Fix doc for regulation_mode of pst. (#1170)
Add contributing and security references to the readme (#1198)
