Changelog

What's new in 3.0.1:

- Fixes multiple windows support;
- Fixes several minor UI issues.

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.

What's new in Juno 2.1:

- Python upgraded to 3.10 and pinned packages updated to their latest releases;
- New packages: 'openai' (for accessing OpenAI APIs), 'tiktoken' (tokenization for OpenAI models), and their dependencies (including 'aiohttp', 'yarl', 'frozenlist', 'multidict', and more);

- Easier package management: Now you can delete and upgrade many pre-installed packages (some will remain pinned, e.g. packages that Juno uses internally);

- A whole bunch of fixes for crashes and bugs, as well as many less prominent enhancements and general quality of life improvements.

Juno 2.1 comes with an upgraded Python environment, significant performance and stability improvements, new packages (including 'openai' for accessing ChatGPT and DALL-E APIs), and much more.

What's new in Juno 2.1.5:

- Fixes several crashes related to background persistence and addresses a couple of issues in the package manager, improving the handling of packages without wheel distributions.

What's new in 2.0.12:
– Fixes several crashes on older versions of iOS;
– Fixes a crash on previewing certain types of links in notebooks;
– Fixes several minor code completion layout issues;
– Makes sure notebook scrolls to caret on orientation changes;
– Fixes certain settings not getting applied in new cells until the notebook reopens;
– Makes sure notebook checkpoints are created and updated using the same logic as in JupyterLab and Jupyter Notebook, i.e. only when you explicitly select Save in menu;
– Updates cell type icons and renames Markdown cell type to Markup Text.

What's new in Juno 2.0:
– Notebook editor: the notebook editing experience has been redesigned from the ground up into a highly configurable notebook workspace, ready to get customized around your personal workflow. The editor has a ton of new features: faster-loading notebooks, cell templates, better image viewer, better previews, easier text and selection manipulation, better keyboard and trackpad support, a ton of new settings, configuration and customisation options, new Find and Replace experience, new document management features — and a lot more! The new notebook editor absolutely shines on iPad, but will work great on iPhone, too.
– Working directory file browser: seamlessly navigate, view and edit files and folders without leaving your notebook. It lets you manage files and directories, as well as perform other actions useful in the context of writing code and working on your notebooks: say, getting a relative path to a file or directory, or quickly editing contents of an arbitrary file as plain text.
– Text editor: view and edit any file from your working directory in a built-in text editor with syntax highlighting, powerful Find and Replace, configurable view options, customisable toolbar and more!
– A whole bunch of minor and major fixes around package manager, keyboard and trackpad handling, scrolling and notebook editor UI in general.

Juno 2.0.12 *still* comes with Python 3.6 on board, but we begin testing Juno with Python 3.10 on TestFlight shortly, and will release it on App Store later this year as a free update.

Juno 2.0.11 *still* comes with Python 3.6 on board, but we begin testing Juno with Python 3.10 on TestFlight shortly, and will release it on App Store later this year as a free update.

This release fixes several issues related to keyboard and scrolling.

Fixes a couple of minor UI issues.

Juno 1.5 comes with a package manager on board! It has a ton of quality of life improvements: you can see all packages that are available to you, both system and user installed; you can delete user-installed packages and install new ones; there is now an easy way to see which dependencies are missing or have incompatible versions, which package releases are likely to work in Juno and which modules the package provides — among many other things!

Juno's package manager introduces a concept of *pinned* packages: you can import and use those as any other package, but you can't upgrade or delete them (as Juno relies on them under-the-hood).

Finally, we've made a bunch of improvements to the package installation process, so Juno can now handle several older-style distribution formats. That said, what you can install is still constrained by the OS restrictions, which means pure Python packages only.

– Multi-window support for iPadOS! You can now edit and run multiple notebooks simultaneously on iPad, each in a separate Juno window — including side-by-side in Split View.
– Improved context restoration, working directory management and a few other things, which needed to accommodate this new multi-window nature of Juno.
– Package installer can now process several older-style distribution formats.
– Fixes for a couple of bugs around file system access.
– Fixes for several minor UI issues.
– Many under-the-hood changes and improvements, which lay important groundwork for future Juno features: this release is just one of a few major updates coming this year. Keep your eyes peeled and follow us on Twitter for more details!

– Fixes a crash and a couple of minor issues in notebook editor

– Adds GDAL, Fiona, PyProj, Shapely and GeoPandas. Enjoy!
– Adds a media viewer for cell output: view generated plots fullscreen, zoom and share!
