Where is version 4.5?

It was found that the code in our project refers to nbformat version 4.5 when cell id field was added but there is no information neither in the Changelog nor in the documentation site:

Although there are some mentions about this version, for example, #189.

Not a big problem, I'm just curious why there is no information about it.

Hi @sineed, the json schema format version is independent of the python package version. Version 4.5 of the schema was introduced in version 5 of the library.

Hi @blink1073 ah now it's clear thanks! Will put a note on that
