Made some #bluesky profile cards for @mystmd.org via the widget interface (widget doesn't feel like right interface, but a handy starting point). Just needed a fetch call to api.bsky.app 🤩 wrote more about it here. more #bsky / #atproto experiments coming. opensci.dev/articles/blu...

New release 🚀 We just shipped several UX and UI bugfixes in the Jupyter Book and MyST stack. - mystmd v1.8.1 jupyterbook.org/releases/mys... - myst-theme v1.1.2 jupyterbook.org/releases/mys... We will get a jupyter-book release out to bring these in as soon as we fix our release infra 😅

Adding an `anywidget` style/based directive & renderer into the core @mystmd.org stack is a big win for custom interactivity and extensibility. My contribution this week: to round off the first cut implementation - based on what've had in prod at @curvenote.com. opensci.dev/articles/ups...

It also standardizes and improves the behavior of links so that interactive, external, and internal links now have distinct and consistent styles so that your readers know what to expect.

This release brings more control over *concurrent execution* of notebook content as part of this build process. This allows you to define the number of simultaneous executions when your book builds to ensure they occur more sequentially, or reduce bugs if notebooks spawn their own parallel processes

We recently pushed Jupyter Book 2, which was a breaking change for many of our users! We considered publishing a completely different package (e.g., `jupyter-book2`) but decided against it. Here's a quick rationale why:

We're also excited to lean into "content as structured data". MyST documents are represented as a structured abstract syntax tree (AST), making them canonical and machine-readable. This enables powerful transformations and remixing across projects.
