Python and Jupyter – Juno

What's New in Juno 4.2.3: This update fixes a range of crashes and stability issues, along with a number of smaller interface fixes and polish. Here's everything new in Juno 4.2: THE PACKAGE MANAGER, REWORKED – Install a package and Juno works out everything else it needs, shows you the plan, and installs the whole set. – Point it at a project's requirements.txt and it does the same for every package the project needs. – Package pages are rebuilt around the project's README, its versions, and what's installed on your device. – Browse popular packages, see when updates are available, and tidy up dependencies left behind when you uninstall. MORE AI PROVIDERS – Use OpenRouter, DeepSeek, Together, or Groq, or point Juno at any OpenAI-compatible endpoint — including a model server running on your own network. – Some providers now let you sign in with your account instead of pasting an API key, and Juno shows how much of its allowance is left. – New models throughout the catalog, with context and account limits shown right in the composer. UPDATED ENVIRONMENT – pandas 3.0, NumPy 2.4.6, scikit-learn 1.9, SciPy 1.18, and lxml 6.1.1 lead a refresh of the bundled packages. MORE – Juno launches faster when you have a lot of packages installed. – A range of stability fixes, including crashes in the code editor, with the iPad keyboard, and when shutting down a kernel.
