Copy link Member QuLogicMay 9, 2025 Choose a reason for hiding this comment The reason will be displayed to describe this comment to others.Learn more. The backport of the#29827 did not include the change of defaults to`check_figures_equal` to only build`png` by default for API stability reasons. Thus the extensions remained explicit on the`v3.10.x`. So any`extensions=['png']` being added here that correspond with`4b51837` can be reverted.
