v0.30.0

0.30.0 (2025-05-09)

There was a change to [email protected] that broke a lot of our assumptions around parsing content from HTML (and the clipboard), which users notified us about. We've now fixed them in this update. This resulted in a fairly significant change to how we parse content, but with a our test suite we are able to guarantee little changes in behavior, in some cases we actually are able to parse and correctly insert more content than prior versions.

There are also a number of bug fixes that have been addressed with this version, especially around collaborative editing, which should mean a better collaborative experience for users.

As always, we would like to thank our sponsors. We've recently updated our website to include a proper user auth and payment system. If your company relies on our open source software, please consider paying it forward by becoming a sponsor via our website: https://www.blocknotejs.org/pricing
