Which is the reason of your problem :)  Single-line regular expressions can't find the \n because it's not part of the line itself, and in a line-based regular expression the line end is $ (as it's the end of the input).

So yes, 1.25 changed behavior by implementing single-line regular expressions and making it the default (because I believed it was more commonly what people were after, esp. because there's a history of people confused by some multi-line results).

This doesn't mean you can't search for \n: you can either switch back to multi-line regular expressions (there's a checkbox just for that), or if you want to search for line ends (e.g. if line ends are not \n in your file(s)), use $ with single-line regexes.
