agenda

• define new goals for the meeting
• discuss the merge strategy for legacy classic and retro
  • where to handle discussions knowing we're replacing one technology with another.
  • Technical steps/questions
    • Do we move retrolab into jupyter/notebook?
    • Dis-entangling NBClassic, JupyterLab, and Notebook
      • NBClassic depends on Notebook and JupyterLab depends on NBClassic.
      • Making RetroLab become Notebook 7.x forces JupyterLab to drop NBClassic as dependency or NBClassic drops it's notebook dependency.
      • Pin nbclassic to 6.x.
• create issues and organize the project board https://github.com/orgs/jupyterlab/projects/2
• status updates - goals, blockers, availability

agenda

• [DRAFT] JEP for Notebook v7

• Frederic: JupyterLab 3.x or 4.0 for notebook 7 issue
  Currently RetroLab (to-be notebook 7) is based on lab 3.x branch. But some new features will be needed for it:

  • Customize widget position to fit with notebook layout
  • Add cells toolbar ([TBC] bringing jlab-enhanced-cell-toolbar in Lab)
  • Add tour (bringing jupyterlab-tour in Lab)
    Cons for 3.x
  • If we do a release 3.x for it, this will strip more reasons to update to JLab 4.
  • If it is linked to 4, this avoid releasing notebook 8 after JLab 4 😉
  • An excuse for extensions authors to modify their extension to be compatible because the API has changed.
    Pros for 3.x
  • Less breaking changes?

  [Afshin] it makes sense regarding the amount of work to be done for notebook v7 that it will be based on JLab 4. Moreover it will be better to not annoy extension authors that just got converted to NPM world to modify again their extensions because we bumped the major version.

• Prepare nbclassic for Notebook 7.
  1. nbclassic the classic notebook ui running on jupyter server
     • Release Notebook static/templates under a separate package (possible on NPM).
  2. nbclassic automatically shims config
     • Copy traits from jupyter/notebook's NotebookApp into nbclassic package
  3. no nbclassic
     • No changes needed
• Drop old notebook traitlets shim from JupyterLab?

There were ~5 others in the meeting that we're captured in this list.

agenda

• From last week

  • Please comment on the following issues if you have opinions.
  • Prepare nbclassic for Notebook 7.
    • Discussion opened here: The future of nbclassic nbclassic#81
  • Drop old notebook traitlets shim from JupyterLab?
    • Question: remove classic notebook server traitlets shim? jupyterlab/jupyterlab#11612

• Jupyter Notebook v7 Enhancement Proposal

  • Entered voting phase this past week
  • Open discussion on the guiding principles for Notebook v7
    • Some voiced the following concern
      • As currently written, there appears to be a tilt towards favoring a "future" experience over preserving the current Notebook experience.
    • A proposed alternative: "Any user facing difference in behavior from V6 is bug".
      • Are we willing to make this strong of a statement?
        • There was concern raised about the strength of this claim.
      • Looking 5 years out, a vast majority of our users are not using Jupyter today.
        • Who do we optimize for—today's users or tomorrow's users?
    • Keep in mind, the spirit of the JEP is captured by the last principle.
      • "Have we done everything possible to minimize the experience gap for users of Notebook v6 (while recognizing, given other constraints, that we can't always eliminate it completely)?"
      • In specific cases mentioned—i.e. accessibility, maintainability, and security—we cannot optimize for user experience gap between v6 and v7.
  • Notes about voting and discussion.
    • JEP is in final round of comments.
    • Complete concensus is not a requirement for JEP approval.
    • The Steering Council's vote determines the outcome.
    • Final comments should happen before December 13th.

agenda

• Accessibility hands on workshop tomorrow @ 9am PST
• [name=Zach]
  • Current status of the JEP:
    • 10 yes, 1 no, 3 abstain, 4 absent.
    • What is needed to pass?
  • Need some clarity from last week's discussion:
    • Question from last week: Can Notebook v6 be installed in the same environment as Notebook v7?
      • Polled some people since last week, and the answers were mixed.
    • If not, I think we should provide clear messaging in Notebook v7 (client-side and in terminal)
      • how to downgrade back to Notebook v6 if absolutely needed
      • where to report changes that break workflows.
    • Upgrading to Notebook v7 is not really an opt-in action.
      • Most people call pip install notebook without an explicit version pin.
      • Defaults to Notebook v7 (not necessarily a problem)
      • Users have to opt-out to get the Notebook v6 experience.
      • Darian's opinion: I think we should allow security patches to notebook v6 but no other releases that add features or even really bug fixes unless they are truly trivial. I think nbclassic should be deprecated. This is my opinion but it did seem to be shared at the last governance call where I brought up the subject. I just don't want to attach other names to ideas I wrote down off the cuff.
    • When do we cut a pre-release?
      • As soon as the JEP is merged.
      • This is low risk, because pip install --pre is an explicit, opt-in action.

    there are 2 goals:

    1. get a pre release sooner than later
    2. cut a proper pre release in a few months

    we'll start a discussion around zachs proposed solution, and go from there.

    • from notebook
      • add retrolab as a dependency to notebook using entry points

Eric Charles

• Draft proposal for JupyterCon by @RRosio @ericsnekbytes @jtpio will be submitted tomorrow
• More CI fixes needed for nbclassic 0.5.0 release
• Notebook 7 has less panels than JupyterLab, which make some existing JupyterLab extensions not working for Notebook 7. Has this already been discussed?
  • Jeremy (will not join the meeting):
    • yes this is by design. Jupyter Notebook is a document-centric interface and not a full blown environment like JupyterLab. We don't want Notebook 7 to be a clone of JupyterLab
    • Most (simple) lab extensions will work in Notebook 7, the complex ones might not
    • support for side panels (hidden by default) was added in 7.0.0a7: https://github.com/jupyter/notebook/releases/tag/v7.0.0a7. The main motivation was to enable support for the popular Table of contents extension, but also other built-in lab extensions like the debugger and the RTC panel

Rosio

• Merged in PR #6609 fix for renaming files into 6.5.x branch

Brainstorming how to make writing extensions for Notebook easier and distinguish which tokens are available/can be depended on in Lab vs Notebook, ideas:

• Extension author can explicitly request a ILabApp dependency (so is jupyterlab available or not) and accordingly act based on its availability to show or not. Thinking more, I don’t think it covers all cases as the jupyterlab app package may be available but the user have launched jupyter notebook.
• jupyterlab does not have the concept of view, whereas for notebook, in the git case, you may add some visuals components in the tree page (on browser tab) and other visuals components in the notebook page (on another browser tab). jlab git extension today does not have to deal with that notion of tree vs notebook.
• In general:
  • expand documentation https://jupyter-notebook.readthedocs.io/en/latest/extending/frontend_extensions.html
  • example extensions
• Ideas on using tokens (or package.json which would allow backwards compatibility) as a place to indicate which frontend is supported.
  • Make a list of tokens working in lab and notebook, notebook-only and lab-only. how to discover this programatically?
    • add a field to Token
    • use the name of Token and @jupyter
    • use docs
    • don't use tokens, use package.json
