Comment 3 for bug 1309856

As far as your question was concerned, the binary I had compiled before the version change in the libsqcintilla2 didn't work after I had upgraded libsqcintilla2 from libsqcintilla2-9 to libsqcintilla2-11.

I just figured that the source package is qscintilla2 which changed from 2.7.2 (last year) to 2.8.1-2 (now)

http://packages.qa.debian.org/q/qscintilla2.html

and had a look at both changelog.gz as well as changelog.Debian.gz . These are the respective outputs for both those packages :-

$ /usr/share/doc/libqscintilla2-11$ zcat changelog.Debian.gz | less
