Since the collective was established in the fall of 2021, some significant items on the approved roadmap have been completed by Igalia. As of the end of February: 

* Approved accessibility work to expose an accessibility tree in the Chromium implementation similar to what is present in WebKit and Gecko on macOS and Linux has been completed

* Very basic mtable support has been added to the Chromium implementation

* Implementation of stretchy/embellished operators.

* Performed refactoring of font-family, and basic support for generic keyword "math".

* Updated the User Agent stylesheet for MathML.

* Fixed misc Chromium bugs found by Google's fuzzer, wpt failures, etc

* Misc improvements to MathML Core spec.

* Updates and further discussions toward a stable & compact operator dictionary

Thanks to all sponsors for helping to support this important work.
