What's New in Juno 4.1.4: HTML files now open in a live web view: pages run their JavaScript and load their own stylesheets, images, and scripts. This update also fixes installing certain packages from source, moving files in the project tree, and a range of stability issues. Juno 4 is our biggest update yet — here's everything new. CODING ASSISTANT – Code alongside an AI assistant in your notebooks and scripts. Bring your own OpenAI, Anthropic, or Gemini API key and stay in full control of your data and usage. PYTHON 3.13 – The built-in environment now runs Python 3.13, with every bundled package — NumPy, pandas, SciPy, Matplotlib, OpenCV, and more — updated along with it. NEW WAYS TO RUN – Python REPL: run code interactively at a prompt — standalone, or drop in after running a script or project. – Project mode: open a folder as a project with a file tree, multiple editor tabs, and a project-aware assistant. – Object Inspector: browse the variables, functions, and imports defined in your session. – Output sidebar: keep previews, the console, a browser, and the inspector side by side. PYTHON MEETS iOS – New juno modules reach the clipboard, Keychain, device info, location, motion, contacts, reminders, photos, sound, notifications, sharing, and Bluetooth — plus native dialogs, full-screen previews, and an Objective-C bridge. – Run Python files and code from Shortcuts and Siri, and keep long-running scripts and sessions going in the background. MORE – A built-in browser for local web servers and HTML, with view-source and console-log forwarding. – One editor for code and text, with syntax highlighting and the coding assistant for both. – Faster package search, collapsible cells, auto-scrolling notebooks, a customizable keyboard toolbar, redesigned settings, and a wide range of fixes and polish. Editing notebooks and files is now free. Running code is a Pro feature — and you can try it, and every other Pro feature, free before you buy.
