This issue affects downstream applications, such as plotly, which depends on nbformat, e.g., in this issue.

[jconwell]

Ran into the same issue. This breaks Plotly usage in notebooks as plotly checks nbformat version > 4.2.0.
For now if you install nbformat==5.5.0 Plotly will work correctly.

Fixed in 5.6.1
