Subject: [PATCH] libicns: 0.8.1 -> unstable-2022-04-10
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

libicns hasn’t had a release in over a decade, but development has
continued upstream. Updating removes the need for the openjp2 patch and
includes fixes needed to build with newer versions of clang.
