+### Important changes
+
+⚠️ **HedgeDoc 1.12.0 and onwards will require Node 20.17 or later in order to run.**  
+Since Node 18 security support was stopped over one year ago, we don't maintain backwards-compatability for that anymore.
+
+Some syntax highlighting languages have been removed and/or changed. You can find more information in
+[the highlight.js docs](https://highlightjs.readthedocs.io/en/latest/upgrade-11.html#built-in-set-of-common-languages).
