Juno 3.0 marks a significant milestone in Python coding experience on iPad and iPhone! We've expanded beyond the Jupyter environment to include a full-fledged Python IDE — it’s specifically designed to make working with .py sources on your iOS devices intuitive and seamless, with as few compromises as possible. This first release already packs a bunch: - A fast and versatile code editor; - Snappy, intelligent code completion; - A console with full terminal emulator support; - A built-in media viewer for code outputs, perfect for displaying Pillow-generated images, Matplotlib plots, Bokeh and Flask web apps, and more. Juno 3.0 also brings a whole new file navigation experience with rich document previews, featuring beautifully rendered Jupyter notebooks, syntax highlighting for source code and text-based formats, and Quick Look for most popular document types and media. Add quick access bookmarks for any file system location, or just open any document in place for preview and editing. Juno 3.0 adds several new packages too, including pyarrow and h5py for HDF5 support.
