Release Notes: Nova 10

Version 10

October 27, 2022

Simply put, it's one of the biggest Nova updates we've ever done. It massively improves our language support, adds a beautiful diff view, has gallons of fixes and improvements, and is ready for you to start coding. Introducing Nova 10.

Supercharged Languages

Many of Nova’s built-in languages have been upgraded to the next level. They parse more accurately, load faster, and work even better.

Tree-sitter Extensions

You can now leverage the expansive grammar community of Tree-sitter, the open-source parsing library used in Nova 10, when writing Nova language extensions.

Comparison View

Slide open a comparison to diff a file against a Git commit or another file, or even diff two specific commits, and quickly see what's changed.
