Unlike Jupyter, NATS (a distributed pub/sub system) is controlled by one company and is planning to leave CNCF, relicense non-open source, etc. This situation makes me appreciate how Jupyter is organized more than ever. - (Darian) A quick update on: "[How to use Foundation funds to support the Jupyter community](https://github.com/jupyter-governance/jupyter-foundation-governing-board/issues/1)" - The foundation governing board met and would like to approach the subprojects on what the official projects/repos we are committed to supporting - Ely - Jupyter Open Studio Day NYC Friday May 23 https://discourse.jupyter.org/t/jupyter-open-studio-day-in-nyc-may-23-2025/34500 - Mike: - Anyone seen `TypeError: 'ABCMeta' object is not subscriptable` crop up on CI recently? https://github.com/jupyterlab/jupyterlab/issues/17521 - IPython [9.2](https://ipython.readthedocs.io/en/stable/whatsnew/version9.html#ipython-9-2) and [8.36](https://ipython.readthedocs.io/en/stable/whatsnew/version8.html#ipython-8-36) released - Preparing to release lumino, looking for an approval on: - https://github.com/jupyterlab/lumino/pull/758 - https://github.com/jupyterlab/lumino/pull/757 - Discussion about windowing mode https://github.com/jupyterlab/jupyterlab/issues/17516 - If we can get this right, it would fix a lot of current issues - Proposal to plan this work out upfront to make sure we get it right - Interest in targetting this towards version 4.5 - Joint frontend/backend call retrospective - Didn't have any joint topics this time - Could share updates from each team - Mike: - Auto save functionality https://github.com/jupyterlab/jupyterlab/issues/14619 - https://github.com/jupyterlab/jupyter-collaboration/pull/479 - Broader initial issue: https://github.com/jupyterlab/jupyter-collaboration/issues/430 - Discussed if we could solve this with saving history through snapshots or ipynbcheckpoints - Could we use some sort of Git/Mercurial data model instead of SQLite - Y.js does support database providers ## Wednesday, April 23 | Name | Affiliation | GitHub | | -----|-------------|--------| | Mike Krassowski | Quansight | @krassowski | | Andrii Ieroshenko | AWS | @andrii-i | | Afshin T.

Maybe Zach Sailer could lead this? - Do we have consensus on what we want to do ourselves before the Jupyter Server and Jupyter Kernels groups also have this discussion? - Team agrees that we propose to have the Jupyter Server team join our meeting next week. Darian will add the proposal to the team compass. - JupyterLab 4.4 blogpost issue https://github.com/jupyterlab/jupyterlab/issues/17498 - Please everyone help develop the blog post - Team aligned with making the blog post cover Notebook 7.4 as well - Darian - Quick update on JupyterLab Desktop conversation from last week and [this thread](https://github.com/jupyterlab/jupyterlab-desktop/issues/890) - Updates have been made in the thread since last week, please review and make any comments - Andrii (again): invitation for everyone to participate in JupyterLab 4.5 release plan discussion https://github.com/jupyterlab/jupyterlab/issues/17449 - Please review the release plan - Proposal to go through the feature plan in this meeting to help plan for 4.5 ## Wednesday, April 16 | Name | Affiliation | GitHub | | -----|-------------|--------| | Dan Yeaw | Anaconda | @danyeaw | | Darshan Paudyal | Quansight | @darshan808 | | A.

[See these stats](https://somsubhra.github.io/github-release-stats/?username=jupyterlab&repository=jupyterlab-desktop&page=1&per_page=5), latest release has 2.2M downloads. - Conversation in the meeting ensued. The sentiment mainly seemed to be that it is a valuable frontend, and if a sustainable plan can be developed, we would treat it as a first-class frontend. - Next step: scoping what it would it would take to maintain the project as a first-class frontend. This effort is probably tied to JupyterLab releases. Darian will post on the issue helping to drive that conversation. - Ely - Jupyter Open Studio Day NYC Friday May 23 https://discourse.jupyter.org/t/jupyter-open-studio-day-in-nyc-may-23-2025/34500 ## Wednesday, April 9 | Name | Affiliation | GitHub | | -----|-------------|--------| | Andrii Ieroshenko | AWS | @andrii-i | | Mike Krassowski | Quansight | @krassowski | | Jeremy Tuloup | QuantStack | @jtpio | | Drake Aiman | Google | @wh1ter4bb1t-js | | William Stein | CoCalc | @williamstein| ### Agenda - Andrii, Mike: - jupyter-collaboration v4.0.0 lab pin issue - Jeremy: - Notebook 7.4.0 release - Fine changing the file browser default? https://github.com/jupyter/notebook/pull/7624 - If yes, will merge and release 7.4.0 final - Curious about features for JupyterLab 4.5? - William: - I am interested in organizing an official extremely welcoming meeting like this one (which I love), but aimed at **"all Jupyter implementations"**, especially not-necessarily-open-source ones. i.e., something where devs from colab, cocalc, deepnote, jupyterlab, nteract, vscode, etc., can compare notes and be aware of design decisions, motivated by the goal of increasing usage of Jupyter overall. (Jupyter-performance was sort of like this.)
