 ### Changed
 
 - We integrated the external file types dialog directly inside the preferences. [#8341](https://github.com/JabRef/jabref/pull/8341)
+- We disabled the add group button color change after adding 10 new groups. [#8051](https://github.com/JabRef/jabref/issues/8051)
 - We inverted the logic for resolving [BibTeX strings](https://docs.jabref.org/advanced/strings). This helps to keep `#` chars. By default String resolving is only activated for a couple of standard fields. The list of fields can be modified in the preferences. [#7010](https://github.com/JabRef/jabref/issues/7010), [#7102](https://github.com/JabRef/jabref/issues/7012), [#8303](https://github.com/JabRef/jabref/issues/8303)
 - We moved the search box in preview preferences closer to the available citation styles list. [#8370](https://github.com/JabRef/jabref/pull/8370)
 - Changing the preference to show the preview panel as a separate tab now has effect without restarting JabRef. [#8370](https://github.com/JabRef/jabref/pull/8370)
