JabRef 3.8 (64-bit)

What's new in this version:

Changed:
- Bibliographic information from web resources can now be used to complete existing entries. This functionality can be accessed via a new button in the entry editor
- URLs can now be passed as arguments to the -import and -importToOpen command line options. The referenced file is downloaded and then imported as usual
- We added integrity check to detect all bibtex keys which deviate from their generation pattern
- We added an integrity check that detects invalid DOIs
- We enhanced the integrity checks testing for biblatex-only fields to be aware of more fields (e.g., location)
- ISBNs not available at ebook.de are now resolved using https://bibtex.chimbori.com/
- When using the ISBN fetcher, the names are now correctly rendered in BibTeX
- We display both the field name journaltitle and journal in BibLaTeX mode as journaltitle only was causing headaches
- We changed the order of the cleanup operations so that the generated file name corresponds to the cleaned-up fields
- Files can now be moved to subfolders named by a custom format pattern, e.g., based on entrytype. The pattern can be specified in the settings like the filename pattern
- 'LaTeXCleanup' action does now escape % signs inside BibTeX fields
- Add the possibility to copy citations of multiple entries to the clipboard
- Custom EntryTypes are now stored independently for BibTeX and BibLatex mode
- Upon the first start of JabRef 3.8 old entry type customizations will be converted to custom types for the set default database mode (BibTeX if not changed to BibLatex)
- Upon opening a file with customized entry types it is now possible to choose which customizations should be stored in local preferences
- The default emacs executable name on linux changed from gnuclient to emacsclient
- Replaces manual thread management with cached thread pool
- Windows and OSX binaries are now signed with a certificate.

Fixed:

We fixed various problems with customized entry types:
- Resetting the preferences now also resets custom entry types
- Importing preferences does no longer duplicate custom entry types
- Potenial problems upon resetting to defaults should be fixed
- Customized standard types (such as @article) are no longer listed as "custom" type in "New Entry" dialog
- Applying changes in the "Custom Entry Types" dialog is now faster

We fixed a few groups related issues:
- "Remove entries from group" no longer removes entries from groups with similar names
- If an entry's group field contains 'a b' it is no longer considered a member the groups 'a', 'b', and 'a b'
- Reading and writing now works for groups that contain special escaped characters in their names

Customizable field content selectors due to popular demand. Content selectors now avoid duplicate words
- We fixed an issue which prevented JabRef from closing using the "Quit" menu command
- We fixed an issue where the file permissions of the .bib-file were changed upon saving
- We fixed an issue which prevented that a database was saved successfully if JabRef failed to generate new BibTeX-keys
- Update check now correctly notifies about new release if development version is used
- The DBLP fetcher has been rewritten and is working again
- Export via commandline in no-gui mode is now working again
- We fixed an issue when JabRef restores its session and a shared database was used: The error message "No suitable driver found" will not appear
- We fixed an issue which caused a metadata loss on reconnection to shared database
- We fixed an issue which caused an internal error when leaving the file path field empty and connecting to a shared database
- We fixed an issue where the BibLaTeX Cleanup did not move the contents of the fields year and month to the field date
- Saving of the Backup-Option in the Preferences does now work
- We fixed an issue which prevented the preference dialog to open on systems with Java 9
