Hi Jan,
No, there has been no official announcement-- this is just a reflection of where the project's been for the past few months (and development had slowed down quite a bit before then). Speaking just for myself, I can probably still be persuaded to review small, well-written PRs that don't risk product integrity (we still use Iodide inside Mozilla for a few things) -- it's just unlikely you'll see any large-scale feature development from Mozilla. As such, we felt it best to make this clear up front.
This only applies to the iodide server, pyodide (python-on-webassembly) development continues separately.
There are a number of other efforts in this space, I'd particularly point to starboard notebooks (
https://starboard.gg) as an exciting new effort that is also free software.
Will
