* https://github.com/jupyter-server/gateway_provisioners/issues/144

* Ian
* I've submitted PRs to `jupyter_client` and `ipyparallel` to make changes for full compatibility with upcoming `ipykernel` 7. They are essentially undoing changes made for compatibility with `anyio` but we are no longer using `anyio` in the planned `ipykernel` 7.
* Intending `ipykernel` 7 release in early September unless other new problems arise.

* Jason
* Community workshops: https://events.linuxfoundation.org/jupyter-workshops/
