Dear friends of math in Wikipedia,
Last year our effort was focused on improving the W3C standard MathML; we shifted the focus this year back to the implementation of Math rendering. A new purely PHP and MathML-based math rendering pipeline is in the making and will be available as an opt-in by the end of the year, simultaneously with the shipment of MathML in the latest Chrome version. Since we do not want to carry on PNG images in the year 2023, we are currently removing them from the rendering pipeline. For 2023, we intend to improve speed and accessibility for mathematical formulae and enable popups (similar to the popups for references) that display semantics when hovering formulae.
All the best André and Moritz
