JupyterLab 4.5.0 is now being used for new OOD Jupyter sessions.
This incident has been resolved.
Surveilléseptembre 15, 2026 à 19:49UTC
A bug in Jupyter AI 3.1.3 is causing idle notebooks to lose data. To remedy this, we will be reverting from Jupyter Lab 4.6.3 (with Jupyter AI 3.1.3) to the previous JupyterLab 4.5.0 release (without Jupyter AI) today

If you have experienced this, check auto-saved Jupyter notebook snapshots in
