JabRef

What's new in this version:

Changed:
- We changed the minimum required version of Java to 1.8.0_172, as 1.8.0_162 has introduced a CPU leak
- We added a validity check for dates in the date and urldate fields
- We added a text file export for 'Find Unlinked Files'
- We added a fetcher based on RFC-IDs
- We changed the implementation of the [shorttitle] key pattern. It now removes small words like a, an, on, the etc. Refer to the help page for a complete overview. Feature request in the forum
- We added a formatter for adding braces around the title field. E.g., title = {ExamPle} becomes title = {{ExamPle}}, which prevents BibTeX to convert it to lower case. You can use it at the cleanup entries functionality
- We added a formatter to ensure correct en dashes in the title field. E.g., title = {Example - illustrative} becomes title = {Example -- illustrative}
- We streamlined the defaults for a cleanup of entries in the case of BibTeX
- The import inspection window now uses the same font size setting as the maintable Feature request in the forum

Fixed:
- We fixed an issue where the export to clipboard functionality could not be invoked
- We fixed an issue with the migration of invalid Look and Feels
- We fixed an issue where JabRef would no longer start, when the option "Override default font settings" was activated
- We fixed an issue where JabRef removed whitespace from the Title-fetcher which resulting in no entries being found
- We fixed an issue where fetched entries from the ACM fetcher could not be imported
- We fixed an issue to enable push to application on macOs again

Removed:
- We removed the GTK Look and Feel from the Options, as it leads to freezes in JabRef on MacOSX and Linux #3995. The GTK Look and Feel is now replaced with the "Nimbus" style as default
