- Drop compatibility or just drop testing?
- Python 3.6 is End-of-Life this month, which means running 3.6 is a security issue after this month.
- Scientific Python community advocated for [dropping 3.6 in June 2020](https://numpy.org/neps/nep-0029-deprecation_policy.html). Incidentally, the same proposal advocates for dropping support for Python 3.7 this month (Dec 2021).
- Several people feel we should drop support for Python 3.6 in a Jan/Feb 3.3 release.

#### Additional discussions

- Triage issue:
- [PR for documenting it](https://github.com/jupyterlab/jupyterlab/pull/11661)
- [issue](https://github.com/jupyterlab/jupyterlab/issues/11660) on team-compass

- JupyterLab 4:
- [GitHub project](https://github.com/jupyterlab/jupyterlab/projects/12)
- [Milestone](https://github.com/jupyterlab/jupyterlab/milestone/61)

- How we handle names (firstName, fullName, familyName)
- https://github.com/jupyterlab/jupyterlab/issues/11657
- [@williamstein] It is important to document what the software will do / what is the purpose of the name. This will orientate the choice of the user
- [@williamstein] Many sites have just "Name" and also a "username" (like @williamstein)... CoCalc has “first_name” and “last_name” and I really regret that and wish it was just “Name”. In CoCalc the name is used for: cursor, avatar (first letter), searching for collabs (can be set to unlisted), and showing in @mentions. In courses, we let the instructor set a fixed name they see for a given account, since students can change their names (this was requested by instructors).
- [@krassowski] Apple defines default/short/long/abbreviated styles: https://developer.apple.com/documentation/foundation/personnamecomponentsformatter
- [@tonyfast] all of these concepts are defined formally in the FOAF core http://xmlns.com/foaf/spec/#glance

These meetings will continue to be held through the holiday season (Dec 22, Dec 29).

#### Agenda

JupyterLab 3.x or 4.0 for notebook 7 [issue](https://github.com/jupyterlab/jupyterlab/issues/11464)
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](https://github.com/jupyterlab-contrib/jlab-enhanced-cell-toolbar) in Lab)
- Add tour (bringing [jupyterlab-tour](https://github.com/jupyterlab-contrib/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 :wink:
- An excuse for extensions authors to modify their extension to be compatible because the API has changed.
**Pros for 3.x**
- [Mike] IMO for Notebook we need prebuilt extension manager
- 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.

- Frederic
- Performance meeting after this one
- New reviewers: next steps?
- Jason Weill @jweill-aws
- Jessica Xu @jess-x
- Piyush Jain @3coins
- Ely @ohrely
- [Mike] can I get triage/review on https://github.com/jupyter/jupyter.github.io (we got an influx of small PRs) - who to ask?
- Bug fix release and translatable string
Should that PR be delayed https://github.com/jupyterlab/jupyterlab/pull/11502?
- RTC trusted outputs
https://github.com/jupyterlab/jupyterlab/pull/11494
- [Pete] origin of Colab's iframe outputs. rather than a dialog could it render the non-interactive outputs (text/plain) for remote outputs, with a button to allow switching to the rich mime types?
- [Tony] accessibility
- [Sylvain] a shield thing by untrusted output
- [Mike] There is already a similar pattern with trust button for the html viewer.
- would you be OK with the arrows always being visible?
[Enhance collapsing heading PR](https://github.com/jupyterlab/jupyterlab/pull/11519)
- Windowed notebook

- Sylvain:
- Some boring CSS changes (removing flexbox for output areas) so that we can use break-inside: avoid-pages for printing notebooks (in nbconvert).
https://github.com/jupyterlab/jupyterlab/pull/11508

- Nick
- JupyterLite update
- offline/custom [python wheels](https://github.com/jupyterlite/jupyterlite/pull/310) and [mathjax](https://github.com/jupyterlite/jupyterlite/pull/419)
- start introducing people to it in docs sites?

- Mike:
- prebuilt extension manager - any work going here?
- To list the packages on PyPI, there is a deprecated API to list packages based on classifiers
- or use NPM to fetch the list and get the directions from package.json
- PyPI seem the best candidate.
- [Nick] extension install providers without concrete implementation
:+1: @krassowski
- Bottom line: we should remove the installation part of the extension manager UI for JupyterLab 4 (keeping the listing part of the installed extensions)

#### Agenda

- Isabela
- Accessibility meeting is right after this one. Come join us!

- Michał Krassowski
- I would like to add two new tags: `tag:Collapsible Headings`, `tag:Virtual Rendering` as there are quite a few bugs related to these features and it gets difficult to navigate them otherwise (they do not have a dedicated package). Does it sound good?
- No objections, and several +1s.

- team-compass
- [transfer classic jupyter/notebook to the jupyterlab organization](https://github.com/jupyterlab/team-compass/issues/132)
- In wait for governance update

- Update reviewers list: call for help.
- (from @jasongrout): If you'd like to be a reviewer or triager, please put your github handle below. Typically we grant triage permissions rather liberally, and (actually, we don't have an official criteria for having merge permissions...this would probably be a good discussion at some point). Note that you can give reviews without having merge permissions, and we encourage you do so.
- I'd like to be a reviewer — Jason Weill @jweill-aws
- Jessica Xu @jess-x : Would love to be reviewer, have merge permission
- Add me to the list - Piyush Jain @3coins
- I would like to be a triager - Ely @ohrely

- Darian

Please comments before next Friday meeting

- Jason Weill
- Updating toc, toc-extension for RetroLab (new 3.2.x version being created by Steven S.?)
- My PR for retrolab: https://github.com/jupyterlab/retrolab/pull/275
- an example of a multi-level dev setup https://github.com/jupyter/accessibility

- Mehmet
- Released [JupyterLab Desktop v3.2.3-1](https://github.com/jupyterlab/jupyterlab-desktop/releases/tag/v3.2.3-1)
- Support for custom Python environments in addition to the bundled environment. [instructions](https://github.com/jupyterlab/jupyterlab-desktop/blob/master/user-guide.md#changing-the-python-environment-used-by-jupyterlab-desktop)
- Upgraded to JupyterLab v3.2.3
- Can we create a conda-forge package?
- Nick says that having a conda package that contains its own environment is a no-go. If the package was changed to use the enclosing environment, that would be very different.

- Jeremy:
- Enable Auto Merge? https://github.com/jupyterlab/jupyterlab/issues/11436
- [Documentation on GitHub](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/incorporating-changes-from-a-pull-request/automatically-merging-a-pull-request)
- We'll have discussion on the issue, and try it out if a few people want to and no objections.
- On-going work on feature parity with the classic notebook, for example scrolling of outputs
- Tweak CSS for scrolled outputs: https://github.com/jupyterlab/jupyterlab/pull/11478
- WIP in RetroLab: https://github.com/jupyterlab/retrolab/pull/288

- Eric
- Opinions on [Add usage messages and request Usage method in the Kernel API](https://github.com/jupyterlab/jupyterlab/issues/11455)?
- related to https://github.com/jupyterlab/jupyterlab/issues/4012 and https://github.com/jupyter-server/jupyter-resource-usage/issues/31 ?
- Like the debug messages, experimenting with this in jlab and ipykernel is the first step, next step is proposing an official kernel message in the kernel message spec.
- Nick mentions these as resources to report on:
- cpu
- gpu
- memory
- file handles

- Carlos
- ICurrentUser: new PR https://github.com/jupyterlab/jupyterlab/pull/11443
- RTC next steps: https://github.com/jupyterlab/jupyterlab/issues/11434

- Nick
- Custom editor factories in retrolab
- needs [mad hacks](https://ipydrawio.readthedocs.io/en/latest/_static/retro/tree/index.html) e.g. replacing the editor, reinstantiating with `_noref`

- Jason Grout
- Any update on the undo changes for 3.x? See https://github.com/jupyterlab/jupyterlab/issues/10791#issuecomment-945848216
- https://github.com/jupyterlab/jupyterlab/issues/10928 was fixed
- Solving the cell move with maintaining the history is a tough problem that needs to be tackled in yjs - Kevin is working on it (ETA 2 weeks)
- There is a new issue on the undo of deleted cells issue which might be related: https://github.com/jupyterlab/jupyterlab/issues/11483 (?)

- Martha
- Settings PR (https://github.com/jupyterlab/jupyterlab/pull/11079) is out of draft and Frederic gave review - more review is welcome! Or just extra testing

#### Agenda

- Martha
- Draft PR for settings ui https://github.com/jupyterlab/jupyterlab/pull/11079! I have a list of questions there if anyone could take a look
[Remove dependency on third-party library for ui-components](https://github.com/jupyterlab/jupyterlab/issues/6890)

- Jeremy:
- Feedback on extension authoring https://github.com/jupyterlab/jupyterlab/issues/11075
- https://github.com/wolfv/jupyterlab-dynext is an interesting development to making extension development easier/lower barrier.
- The Jupyter Releaser works well with JupyterLab Extensions :+1: (see cookiecutter config)

- Frederic
- Remove old phosphor class to reduce CSS class stack (goal improve performances by reducing style computation complexity)
- This implies upgrading @lumino packages to the next major version
- Opportunity to update typescript
- Need to wait for IPyWidgets v8 to be compatible to lumino

- Mehmet
- Desktop App upgrade to JupyterLab 3.1.10 along with dev tooling upgrades
- Generates GUI installers for macOS, Debian, Ubuntu, Red Hat, Fedora and Windows
- Bundles a conda environment using Constructor
- GitHub Actions integration
- https://github.com/jupyterlab/jupyterlab_app/pull/191
- Installers at https://github.com/jupyterlab/jupyterlab_app/actions/runs/1235190813

- Konstantin
- JupyterLab LaTeX extension
- [jupyterlab-latex 3.1.0](https://pypi.org/project/jupyterlab-latex/3.1.0/) - federated extension now
- Becoming a maintainer?
- +1 from @jasongrout to you becoming a maintainer for jupyterlab-latex - thanks! @blink1073 - I added you as a maintainer on the repo
- Incoming group of 5 Georgia Tech students working on Computer Science Junior Design Capstone project we proposed. Improvements to LaTeX experience in JupyterLab:
- bibliography tools
- journal templates repository
- drag-and-drop support for plots and data frames from Jupyter notebook into the editor
- simplified uploads of figures into the publications
- UI to quickly create tables, equations and find mathematical symbols
- Discussion: do these features belong in the extension? Or is it something out of scope/should be in separate extension?
- ~~CoCalc/Colab perspective: How do we support notebooks with bibliography (say) in a consistent way...?~~ (I thought this had to do with Jupyter notebooks, but it doesn't.)

- Steve
- [JupyterLab v3.1.12](https://github.com/jupyterlab/jupyterlab/releases/tag/v3.1.12) - First fully automated stable release!
- To learn how to use the releaser, good places are the configuration files for other repo: jupyterlite, voila
- [JupyterLab v4.0.0a9 ](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.0.0a9) and [JupyterLab v4.0.0a10](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.0.0a10) (in progress during meeting)
- [Configurable Probot Binder link](https://github.com/jupyterlab/jupyterlab-probot#configuration) - opt-in, currently used in [JupyterLab](https://github.com/jupyterlab/jupyterlab/pull/11039) and [Lumino](https://github.com/jupyterlab/lumino/pull/229)

#### Additional discussions

- Frederic
- benchmark tests
- [Michal] It seems there is a bit of a jitter due to VMs with different processors being assigned. Would it be a good idea to try to divide the time by some performance score from a third-party benchmark of a processor and show it as "normalized score" in addition to time lapsed?
- Another option is a self-hosted runner that only runs on push, maybe using our project AWS credits. https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners
I think the best we can do is deal with the runner differences and have a large threshold for change, which is what this action does: https://github.com/rhysd/github-action-benchmark
Follow up :construction: change the logic to switch to manual to launch more experiments to improve statistical information by comparing the base node of the PR and the head (we want to be independent of the evolution of master).
- Sponsors: What about adding NumFocus sponsor badge on JupyterLab projects as conda-forge does? `jupyter.org` uses this [link](https://numfocus.salsalabs.org/donate-to-jupyter/index.html)
