#JupyterLab 4.6 and #Jupyter #Notebook 7.6 are out! blog.jupyter.org/jupyterlab-4...

Hey @github.com any way you could tune the spam filters?

#JupyterLab 4.6 and #Notebook 7.6 release candidates are now available for testing. One week to go before a final release. If you have a large deployment, or maintain Jupyter extensions - this is the time to do a final test before the stable release goes out!

Second beta of #jupyterlab (codename `4.6.0b1`) is now available: github.com/jupyterlab/j...

JupyterLab 4.6 beta is now available for testing 🎉. It includes: - new layout customization options - navigation between recently edited cells - revamped keyboard shortcuts UI - editable breadcrumbs in file browser - debugger improvements Full changelog: jupyterlab.readthedocs.io/en/latest/ge...

Dear programming hivemind: do not buy @logitechgaming.bsky.social even if that's the only option to get TKL. When their keyboard breaks, the support will baselessly require installing GHub (which they do not support on Linux, and which cannot be installed on corporate OS) in order to verify warranty

Hot off the press: a new JupyterLab extension that brings advanced, interactive visualizations to your JSON, YAML, and CSV files, powered by the jsoncrack library. ➡️ Repo: github.com/jtpio/jupyte... 💡 Try it in the browser: jtpio.github.io/jupyterlab-j...

If you are using AI to open PRs without considering previous reviews and ignoring PR templates, you are not adding value. The point of good first issues was to let humans learn the contribution flow, not for AI to score virtual points.

#JupyterLab 4.5.5 and 4.6.0a3 are out 🚀 v4.5.5 includes bug fixes for: - table of contents in Markdown - theme settings in non-English locales - comms subshell resource management - slow selection of lines in editor - scroll anchoring

A viewer for Parquet, SQLite, and Avro files in JupyterLab. Check out our new JupyterLab extension: Arbalister. 🏹 Built upon Apache Datafusion, @jupyter.org , and @arrow.apache.org , it lazily fetches rows so that you can view files larger than memory! blog.jupyter.org/instantly-vi...

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.

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-...

Tired of complex cloud setups? Quansight's Nebari makes JupyterHub deployment a breeze. Scalable, secure, and ready in half an hour. Dive into the details: https://buff.ly/3WPvg7Y #Jupyter #OpenSource

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!
