 ### Changed
+- Implemented [#756](https://github.com/JabRef/jabref/issues/756): Add possibility to reformat all entries on save (under Preferences, File)
 - Comments and preamble are serialized with capitalized first letter, i.e. `@Comment` instead of `@comment` and `@Preamble` instead of `@PREAMBLE`.
 - Global sorting options and preferences are removed. Databases can still be sorted on save, but this is configured locally and stored in the file
 - OvidImporter now also imports fields: doi, issn, language and keywords
