 - We fixed an issue where the file path is invisible in dark theme. [#7382](https://github.com/JabRef/jabref/issues/7382)
 - We fixed an issue where the secondary sorting is not working for some special fields. [#7015](https://github.com/JabRef/jabref/issues/7015)
 - We fixed an issue where changing the font size makes the font size field too small. [#7085](https://github.com/JabRef/jabref/issues/7085)
+- We fixed an issue with TexGroups on Linux systems, where the modification of an aux-file did not trigger an auto-update for TexGroups. Furthermore, the detection of file modifications is now more reliable. [#7412](https://github.com/JabRef/jabref/pull/7412)
 - We fixed an issue where the Unicode to Latex formatter produced wrong results for characters with a codepoint higher than Character.MAX_VALUE. [#7387](https://github.com/JabRef/jabref/issues/7387)
