JabRef 5.7

What's new in this version:

Added:
- We added a fetcher for Biodiversity Heritage Library
- We added support for multiple messages in the snackbar
- We added an extra option in the 'Find Unlinked Files' dialog view to ignore unnecessary files like Thumbs.db, DS_Store, etc. koppor#373
- 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
- We added a feature to drag selected entries and drop them to other opened inactive library tabs koppor521
- We added support for the biblatex-apa legal entry types Legislation, Legadminmaterial, Jurisdiction, Constitution and Legal

Changed:
- The file column in the main table now shows the corresponding defined icon for the linked file 8930.
- We improved the color of the selected entries and the color of the summary in the Import Entries Dialog in the dark theme
- We upgraded to Lucene 9.3 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
- We improved the Latex2Unicode conversion
- Writing BibTeX data into a PDF (XMP) removes braces
- Writing BibTeX data into a PDF (XMP) does not write the file field.
- Writing BibTeX data into a PDF (XMP) considers the configured keyword separator (and does not use "," as default any more)
- The Medline/Pubmed search now also supports the default fields and operators for searching. forum#3554
- We improved group expansion arrow that prevent it from activating group when expanding or collapsing
- When configured SSL certificates changed, JabRef warns the user to restart to apply the configuration.
- We improved the appearances and logic of the "Manage field names & content" dialog, and renamed it to "Automatic field editor"
- We improved the message explaining the options when modifying an automatic keyword group
- We moved the preferences option "Warn about duplicates on import" option from the tab "File" to the tab "Import and Export". koppor#570
- When JabRef encounters % Encoding: UTF-8 header, it is kept during writing (and not removed)
- 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 to find those characters.

Fixed:
- an issue where the user could not rate an entry in the main table when an entry was not yet ranked
- an issue that caused JabRef to sometimes open multiple instances when "Remote Operation" is enabled
- an issue where linked files with the filetype "application/pdf" in an entry were not shown with the correct PDF-Icon in the main table 8930
- an issue where "open folder" for linked files did not open the folder and did not select the file unter certain Linux desktop environments
- an issue where the content of a big shared database library is not shown
- the unnecessary horizontal scroll bar in group panel
- an issue where the notification bar message, icon and actions appeared to be invisible
- an issue where deprecated fields tab is shown when the fields don't contain any values
- an issue where an exception for DOI search occurred when the DOI contained urlencoded characters
- an issue which allow us to select and open identifiers from a popup list in the maintable, 8802
- an issue where the escape button had no functionality within the "Filter groups" textfield. koppor#562
- an issue where the exception that there are invalid characters in filename
- When the proxy configuration removed the proxy user/password, this change is applied immediately.
- an issue where removing several groups deletes only one of them
- an issue where the Sidepane (groups, web search and open office) width is not remembered after restarting JabRef
- a bug where switching between themes will cause an error/exception
- a bug where files that were deleted in the source bibtex file were kept in the index
- "Error while sending to JabRef" when the browser extension interacts with JabRef. JabRef-Browser-Extension#479
- a bug where updating group view mode (intersection or union) requires re-selecting groups to take effect
- a bug that prevented external group metadata changes from being merged
- the shared database opening dialog to remember autosave folder and tick

Removed:
- We removed the social media buttons for our Twitter and Facebook pages
