### Removed
- Ampersands are no longer escaped by default in the `bib` file. If you want to keep the current behaviour, you can use the new "Escape Ampersands" formatter as a save action.

The class LinkedFile already contains a method that does this job:

jabref/src/main/java/org/jabref/model/entry/LinkedFile.java

Lines 162 to 164 in 8520833

public boolean isOnlineLink() {
return isOnlineLink(link.get());
}

Can you please use it. I would also suggest to add the normalization trim().toLowerCase() there, which I find a nice addition.

Concerning isOnlineLink(): I would recommend removing "toCheck.contains("www.")", because a path to a local file might contain this pattern coincidentally. What do you say?

{
if (filePath == null) {
return false;
}
String normalizedFilePath = filePath.trim().toLowerCase();
if (normalizedFilePath.startsWith("http://") || normalizedFilePath.startsWith("https://")) { // INFO: can be extended, if needed
return true;
}
return false;
}
}
