JabRef 5.7 + Portable

Added:
We added a fetcher for Biodiversity Heritage Library. 8539
We added support for multiple messages in the snackbar. #7340
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%..Localharawatajabrefversionlogs, Mac: Users/.../Library/Logs/jabref/version
We added an importer for Citavi backup files, support ".ctv5bak" and ".ctv6bak" file formats. #8322
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 #8931
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. #7927
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 #8639
Writing BibTeX data into a PDF (XMP) removes braces. #8452
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. #7982, #3176
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". #6536
We improved the message explaining the options when modifying an automatic keyword group #8911
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). #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 to find those characters.
Fixed:
We fixed an issue where the user could not rate an entry in the main table when an entry was not yet ranked. #5842
We fixed an issue that caused JabRef to sometimes open multiple instances when "Remote Operation" is enabled. #8653

We fixed an issue where the notification bar message, icon and actions appeared to be invisible. #8761
We fixed an issue where deprecated fields tab is shown when the fields don't contain any values. #8396
We fixed an issue where an exception for DOI search occurred when the DOI contained urlencoded characters. #8787
We fixed an issue which allow us to select and open identifiers from a popup list in the maintable #8758, 8802
We fixed an issue where the escape button had no functionality within the "Filter groups" textfield. koppor#562

When the proxy configuration removed the proxy user/password, this change is applied immediately.
We fixed an issue where removing several groups deletes only one of them. #8390

We fixed "Error while sending to JabRef" when the browser extension interacts with JabRef. JabRef-Browser-Extension#479
We fixed a bug where updating group view mode (intersection or union) requires re-selecting groups to take effect. #6998

We fixed the shared database opening dialog to remember autosave folder and tick. #7516
Removed:

Changed:
We integrated the external file types dialog directly inside the preferences. #8341
We disabled the add group button color change after adding 10 new groups. #8051
We inverted the logic for resolving BibTeX strings. This helps to keep # chars. By default String resolving is only activated for a couple of standard fields. The list of fields can be modified in the preferences. #7010, #7102, #8303

We fixed an issue about empty metadata in library properties when called from the right click menu. #8358
We fixed an issue where someone could add a duplicate field in the customize entry type dialog. #8194
We fixed a typo in the library properties tab: "String constants". There, one can configure BibTeX string constants.
