- We removed wrapping of string constants when writing to a `.bib` file.

- JabRef now writes log files. Linux: `$home/.cache/jabref/logs/version`, Windows: `%APPDATA%\..\Local\harawata\jabref\version\logs`, Mac: `Users/.../Library/Logs/jabref/version`
- We added an importer for Citavi backup files, support ".ctv5bak" and ".ctv6bak" file formats. [#8322](https://github.com/JabRef/jabref/issues/8322)

### Changed

- The file column in the main table now shows the corresponding defined icon for the linked file [8930](https://github.com/JabRef/jabref/issues/8930).
- We improved the color of the selected entries and the color of the summary in the Import Entries Dialog in the dark theme. [#7927](https://github.com/JabRef/jabref/issues/7927)
- 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.

- When JabRef encounters `% Encoding: UTF-8` header, it is kept during writing (and not removed). [#8964](https://github.com/JabRef/jabref/pull/8964)
- We replace characters which cannot be decoded using the specified encoding by a (probably another) valid character. This happens if JabRef detects the wrong charset (e.g., UTF-8 instead of Windows 1252). One can use the [Integrity Check](https://docs.jabref.org/finding-sorting-and-cleaning-entries/checkintegrity) to find those characters.
