Jupyter Core 5.0 Major Release

[jasongrout]

We have a few issues that would require a major release. This issue coordinates work for a 5.0 major release

See the project board for issue tracking for 5.0: https://github.com/orgs/jupyter/projects/6

• Also Jupyter --paths incorrect output #228 looks good to tackle, which probably does not require a major release.

https://github.com/jupyter/jupyter_core/releases/tag/5.0.0rc0 is now available for testing

https://pypi.org/project/jupyter-core/5.0.0rc1/ fixes the version handling in version.py.

I created #294 to track elaborating in the changelog about the changes that can affect users.

I would like to highlight the comments #291 (comment)

In particular what should we do about the lab configuration? If the configuration starts to be in CWD by default, lots of user will have a hard time figuring out

• why their settings are not loaded any longer or are inconsistent
• and as pointed by @kevin-bates why the config folder is visible

After 5.0.0rc2, the cwd is no longer included at all. @kevin-bates can you please see if you're getting the same behavior?

[kevin-bates]

@blink1073 - jupyter_core==5.0.0rc2 no longer creates the lab/workspaces folder in the user's home directory when invoking Lab from that directory (per my previous observation). I also reconfirmed the issue using 5.0.0rc1.

Great, thanks!

I plan to make the release tomorrow, with the release notes here.
