 ### Changed
 
+- We upgraded to Lucene 9.2 for the fulltext search.
+  Thus, the now created search index cannot be read from older versions of JabRef anylonger.
+  ⚠️ JabRef will recreate the index in a new folder for new files and this will take a long time for a huge library.
+  Moreover, switching back and forth JabRef versions and meanwhile adding PDFs also requires rebuilding the index now and then.
+  [#8868](https://github.com/JabRef/jabref/pull/8868)
 - We improved the Latex2Unicode conversion [#8639](https://github.com/JabRef/jabref/pull/8639)
 - Writing BibTeX data into a PDF (XMP) removes braces. [#8452](https://github.com/JabRef/jabref/issues/8452)
 - Writing BibTeX data into a PDF (XMP) does not write the `file` field.
