Pressbooks Product Updates March 2025

New Features

PDF Previews
Now, when you export your book, you’ll see a preview of the PDF before finalizing the download. This allows you to catch formatting issues, review page layouts, and ensure everything looks as expected—saving time and avoiding multiple exports. We’ve also improved the PDF preview on the diagnostics page for more accurate results.

Math Display Improvements
We’ve upgraded our MathJax integration, adding support for new inline delimiters. This means equations and formulas will now display more accurately and consistently across different formats, improving readability for students and educators. You can find more details on this update in our new feature highlight below.

🚨  New Feature Highlight 🚨 

Improved Support for Mathematical and Scientific notation in Pressbooks

We’re thrilled to announce that we’ve made it easier than ever before for authors to write and display mathematical and scientific notation in Pressbooks using our built-in LaTeX/MathJax solution.

What’s New?

  • More Delimiters: You can now use conventional LaTeX delimiters like \( … \), \[ … \], and $$ … $$ in addition to the existing [latex] and $latex shortcodes.
  • Expanded Package Support: We’ve added support for several commonly used LaTeX packages, including AMS math, chemistry formulas, physics notation, color formatting, and more.
  • Full support for EPUB and PDF exports: Expressions will be automatically rendered as accessible images in offline export files where MathJax is not available (like PDF and EPUB).
  • MathJax upgrade: Expressions will now be rendered in the browser using MathJax 3, which includes several improvements (https://docs.mathjax.org/en/v3.2-latest/upgrading/whats-new-3.0.html

  • Better Labels for Checkboxes: The export page checkboxes are now clearly labeled for better usability.
  • Licensed Image Fix: Licensed images now have proper accessibility labels.
  • Non-Latin Characters: We’ve fixed an issue with taxonomy terms using non-Latin characters.
  • Performance Boost: We’ve made various backend optimizations to make the platform faster and more stable.
  • Styling Fixes: We’ve made some small UI tweaks, including better button styles for call-to-actions.
