Is PhosphorJS no longer supported?

I just noticed today that the phosphor github repo has been archived by the owner. Since Phosphor “is used as the underlying architecture of JupyterLab” what risk does this pose to JupyterLab?

There is a discussion here about the transition to lumino. More here about how JupyterLab 2.0 will depend on it.

Migrating extensions is covered here.

the TL:DR of this is it got a name change, and is an official Jupyter project now. It’s still the same software.

Thank you. I just missed the name change.

Long live lumino!
