# [Jupyter Frontends and Accessibility and Server and Kernels Weekly Meeting Minutes](https://hackmd.io/Y7fBMQPSQ1C08SDGI-fwtg)

- What: topics related to JupyterLab, Jupyter Notebook, frontends and accessibility. (Note: accessibility topics are welcome in all meetings, but members of the [Jupyter Accessibility](https://github.com/jupyter/accessibility) subproject make an effort to attend the first meeting of each calendar month.)
- on every first meeting on calendar month please add "Accessibility" section to agenda and
- if there is nothing in "Accessibility" section, let's fallback to triaging/discussing issues with [tag:Accessibility](https://github.com/jupyterlab/jupyterlab/issues?q=is%3Aopen+is%3Aissue+label%3Atag%3AAccessibility)
- When: Wednesdays [9AM Pacific Time](https://www.thetimezoneconverter.com/?t=9%3A00%20am&tz=San%20Francisco&)
- Where: [Zoom](https://zoom.us/j/95228013874?pwd=Ep7HIk8t9JP6VToxt1Wj4P7K5PshC0.1)

* Can we have official renaming of this meeting and the hackmd notes to include server and kernel, now that the separate server/kernel meeting has been removed?
* Mike: "Jupyter Frontends and Accessibility and Server and Kernels" or just "Jupyter Core Meeting"?
* Ian: I prefer the latter, and we can have the full list in the subsequent text (e.g. meeting description).
* Using "Jupyter Applications", need to check how to change the super-title of the hackmd notes.
* For now, changed to "Jupyter Contributor Meeting: Frontends, Kernels, Server, Accessibility"

* Matthias:
* update on agent triaging:
* some stats
* how to proceed discussion
* Maybe taking some ideas from the [PR Triage board](https://github.com/orgs/jupyterlab/projects/11/views/1) is a way to proceed with triaging issues. Jason and Matthias will explore this offline.

* npm trusted publishers: https://github.com/jupyterlab/jupyterlab/issues/17993
* Requires npm>11.5.1: https://github.com/jupyterlab/maintainer-tools/pull/259
* Next step: Jeremy is testing the workflow with the next notebook release (which publishes multiple packages)

- Matthias (@mmesch):
- best place to centralize information on Accesibility projects?
- continued issue trimming if time permits.
- Will email the accessibility council email list and open an issue in the accessibility issue

* Mike
* Planning to release JupyterLab 4.5.0b1 today/tomorrow
* We are now testing on Firefox :tada: https://github.com/jupyterlab/jupyterlab/pull/17965
* I'm tagging new enhancement/feature PRs for 4.6, if you do not agree on any specific PR please speak up/write a comment
* Updated council automation and membership in https://github.com/jupyterlab/council/pull/35 and https://github.com/jupyterlab/council/pull/34

* Action item: add the LF project managers to jupyter-server council google group
* Action item: I updated the JupyterLab council email list to be inactive (restricted posting, changed description to say it is inactive and superseded by the jupyter-frontends council list, etc.). Can we do the same for the jupyter-notebook council google group?

- Andrii: testing Python 3.14, is JupyterLab 4.5.0b0 / 4.4.9 working for you in fresh installs / fresh environmemts?

* Mike
- First JupyterLab 4.5.0 beta is out:
- changes since alpha 4: https://github.com/jupyterlab/jupyterlab/releases/tag/v4.5.0b0
- give it a try on binder https://mybinder.org/v2/gist/krassowski/f2ae89714e8ce043355f8d709212d8e1/HEAD?urlpath=lab
- install it from PyPI https://pypi.org/project/jupyterlab/4.5.0b0/ (or conda-forge)
- getting more testing on try.jupyter.org
- maybe separate subdomain
- cross-linking them via in-app notifications?
- maybe a separate button?
- make it easier to report issues
- should we make it possible to `dispose()` the lumino `Application`? https://github.com/jupyterlab/lumino/issues/766
- Reloading extensions is not possible and breaks API https://github.com/jupyterlab/jupyterlab/issues/17854
context: we have `deactivate()` in lumino since v2 https://github.com/jupyterlab/lumino/pull/377
- [Nick] Create a new plugin base class that is more opinionated and makes the plugin process more streamlined. For example, the base class has a deactivate method required. Or even better, make plugin development much more streamlined for simple cases. For example, could you make a plugin that is just a generator function, where we yield back to you in different lifecycle phases of a simple plugin? A huge incentive here is lowering the friction for boilerplate things. For example, signal lifecycle management - can we keep track of signals that you listen to and automatically unregister them in a deactivate method?

* Balaji Alwar and Chanbin Park
* JupyterLab-a11y-checker extension intro & learnings from usage of axe engine. https://docs.google.com/presentation/d/1u4Jtsp8IMqG-YFlssIMbs0OtQlr9gppAt7sVtzR4vo8/edit?usp=sharing
* The end user here is a notebook author to add things like image alt text, fixing contrast in embedded images, etc.
* There is an ongoing discussion about Jupyter AI integration you might be interested in looking at: https://github.com/orgs/jupyter-ai-contrib/discussions/1
* also, feel welcome to open issues on https://github.com/jupyterlab/jupyterlab/issues suggesting any extension points that would make your life devloping this extension easier
* Experimented with asking an LLM to look at a notebook and detect/fix issues, but for now we are focusing on interactive fixing.
* See also https://github.com/jtpio/jupyterlab-browser-ai/pull/2 and https://arxiv.org/html/2503.20089v1

### Accessibility Topics

### Agenda

* Jeremy:
* Quick open in core JupyterLab? https://github.com/jupyterlab/jupyterlab/pull/17846
* [Nick] File operations are blocking. Don't use https://pypi.org/project/aiofiles/ - you're better off owning your own threads.
* [Nick] Can we expand this to a more general search? API also probably should have a time limit for the operation

* Ian
* Update on subshells. Blockers for ipykernel 7.0.0 release:
* ipykernel bug using debugger in JupyterLab
* ipympl release

* Jason
* [Community call](https://blog.jupyter.org/jupyter-community-call-september-2025-e4d2cfa3ea41) tomorrow
* [Jupyter workshops CFP](https://blog.jupyter.org/jupyter-community-workshops-are-back-3cca15d02975) open until Sunday
* [Jupyter Foundation proposal CFP](https://blog.jupyter.org/your-ideas-our-support-jupyter-community-call-for-funding-proposals-f4642590ae76) open until Sep 28

* Andrii
* Should we discuss kernel message mutation in https://github.com/jupyter/notebook/pull/7713 potentially? See discussion at https://github.com/jupyter/notebook/pull/7713#discussion_r2313339435

### Off the Record

* Jason
* Thoughts about combining this and server/kernels dev meeting?
* Andrii: I think that would make a lot of sense
* Let's try this again next week. Vidar will attend the server/kernels meeting for the next few weeks. We'll plan to make a decision 2 weeks from today for going forward.

* Vidar
* I still have a PR for Lumino (https://github.com/jupyterlab/lumino/pull/291). I saw there was a triage board added, not sure if relevant or not.
* Project at https://github.com/orgs/jupyterlab/projects/11/views/1 - it is read-only and meant to be a helpful experiment. This does not add any process for PRs. Feel free to view/search the project board if it is helpful.
