We’ve come a long way toward one of Wolfram Mathematica’s signature features: 2D mathematical input. This “syntax sugar” transforms plain text like Sqrt into properly typeset square roots and fractions, helping blur the line between writing code and presenting mathematics.

Your maintainers, Kirill Vasin (@JerryI) and Kirill Belov (@KirillBelovTest ), are happy to announce that we’ve finally reached this milestone by adding the last missing piece to the cell editor: auto-adjustable brackets/parentheses:

The expression above is fully editable—unlike in Wolfram Cloud, where similar input is effectively “backed” by a static representation

It might still be buggy, therefore we marked this release as candidate. Please, install the previous version if you prefer stability.

It would be a shame if we took all the credit. We’re truly grateful to Marijn Haverbeke —an outstanding programmer, the author of the JavaScript bible Eloquent JavaScript, and the creator of CodeMirror 6, the core component behind WLJS Notebooks. He was also kind enough to answer our dumb questions on his website—for free 🥰

And Merry Christmas to everyone ❤️
