JupyterLab 4.5 and Jupyter Notebook 7.5 are here! 🎉 Highlights 🎁 - Enhanced notebook scrolling behavior - Native audio and video support - New Terminal search - Debugger, Notebook and File Browser improvements Check out the blog post to learn more! blog.jupyter.org/jupyterlab-4...

Introducing Molview - the ipython/jupyter widget version of nano-protein-viewer🔍:

I used to think the friction in community OSS/corporate dynamics comes from a difference in culture between organizations and teams. The more I see the same team flip between amazing and questionable contribution trajectory the more I think this comes down to changing internal direction/incentives.

It is hard to express criticism as an established maintainer. The words which I could say as a user now hit differently, even if I mean the same thing.

There are two things you should not remove when transitioning to a metapackage: integration tests and documentation. In fact, the transition should double down on these two things as they are critical to ensure the packages integrate well, and that discoverability is preserved.

A mismatch of expectation on what irks #OSS maintainers: I saw folks really worry about removing a feature I contributed due to lack of bandwidth to port it to new version - but this was absolutely fine! I saw them remove tests and ignore my warning against it - and this is what in fact made me sad.

New exciting features are coming to #JupyterLab 4.5.0. Please test the release candidate before & during the JupyterCon (next week!) Major enhancements around: - performance and scroll stability - notebook editing - table of contents - debugger - terminal jupyterlab.readthedocs.io/en/latest/ge...

We've learned that our member communities care a *lot* about cloud cost transparency and reliability, so we're working hard to drill down into user data about costs and usage for community leaders to access.

👋 JupyterLab and Jupyter Notebook users: What's one thing you'd love to see improved in JupyterLab, Jupyter Notebook, or JupyterLite? The team is prepping the upcoming 4.5/7.5 releases and wants to tackle some usability issues. Drop your feedback below, this will help prioritize what gets fixed!👇

JupyterLab 4.4 and Jupyter Notebook 7.4 will be available very soon. And they are coming with a couple of nice improvements and bug fixes 🎁 So I just published a new video to do a quick tour of these new features 🎥 www.youtube.com/watch?v=YhYo...

JupyterLab 4.4.0b1 and Notebook 7.4.0b1 are available for testing 🎉 - improved code console - settings import/export - better real time collaboration - workspace indicator - kernel subshells Please test: pip install --pre 'jupyterlab>=4.4.0b1' or pip install --pre 'notebook>=7.4.0b1'

JupyterLab 4.4.0b1 and Notebook 7.4.0b1 are available for testing 🎉 - improved code console - settings import/export - better real time collaboration - workspace indicator - kernel subshells Please test: pip install --pre 'jupyterlab>=4.4.0b1' or pip install --pre 'notebook>=7.4.0b1'

The Binder team recently made environment builds faster and simpler! Here's a post describing how: blog.jupyter.org/simplifying-...

The PR improving the JupyterLab code consoles has been merged, and is now available in the latest JupyterLab, Notebook and JupyterLite pre-releases! ➡️ pip install --pre jupyterlab notebook 💡We're working on making the new options available in the JupyterLite REPL, stay tuned! 💡

#JupyterLab 4.3.5 is available. Includes fixes for: - scroll restoration on undo/redo - accessibility: color contrast and missing titles - disabling fuzzy filtering in file browser - general stability - execution indicator restoration (for server-side execution) github.com/jupyterlab/j... #jupyter

JupyterLite 0.5.0 is now available🎉 This release is based on the latest JupyterLab 4.3 and Jupyter Notebook 7.3, and includes features such as the notebook minimap and a new "execute" config for the REPL 🎁 It also comes with a fix for better handling kernel restarts. Enjoy!

RTC: prefix has been a roadblock in wider adoption of #jupyter collaboration as many extensions did not support it. The RTC prefix is no more thanks to content providers pioneered by @davidbrochart.bsky.social 🎉 To test it: pip install --pre "jupyterlab>=4.4.0a2" "jupyter-collaboration>=4.0.0a0"

Persist: A fantastic JupyterLab extension (+ research paper) by Kiran Gadhave, Zach Cutler, and @alex-lex.bsky.social. Persist captures interaction provenance, making interactions persistent and reusable. 👏 More details on their blog post with code at vdl.sci.utah.edu/blog/2024/05.... 📊

And the Jupyter Notebook releases are now also available 🎉 - github.com/jupyter/note... - github.com/jupyter/note... Please try and report issues if you find any, thanks!

Two new JupyterLab releases out today: 4.3.4 with a bunch of bug fixes, and 4.4.0a1 with two prominent changes: - new settings import function - a fix for a bug preventing scrolling away from some cells (by pulling patched CodeMirror versions) github.com/jupyterlab/j... github.com/jupyterlab/j...

PSA for the umpteenth official contacting @projectjupyter.bsky.social asking us to fill out some kind of "security vendor assessment" - please read this. We're an open source project, not a vendor. We don't hold your data, we don't sell you anything: jupyter.org/security#ven...
