Rendering Core Weekly Update for January 3, 2023

[Stephen Chenney]

Happy New Year to you all.

Nothing much happened in the last week, as expected. Note that the update document has been renewed to this link: https://docs.google.com/document/d/1AK_PzaiMpSHrJRvMhcnK-FFYXc64Qx_sidx3umsHDRY/edit?usp=sharing

I've updated the calendar entry to reflect the new doc link.

The next meeting is next week, where we will review Q1 2023 OKRs.

Cheers,

Stephen.
