Jupyter-JSC got a new and improved backend. This means that Jupyter-JSC will run even more stable in the future and be able to support a larger number of concurrent users!
Improved starting procedures for services also mean that you now get more detailed and meaningful error messages, should the spawn of your JupyterLab fail.
Along with the backend changes, Jupyter-JSC's UI also got updated! To check out the updates, head over to the documentation.
