Hi, here's a headsup for the upcoming removal of the jasper JPEG200 library for stretch (and the archive in general). It's been unmaintained for nearly a decade, please als see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812630
A removal tracker has been setup by the release team at h ttps://release.debian.org/transitions/html/jasper-rm.html I'll start filing bugs in a week or so (initially with non-RC severity, but they will be upgraded after a few weeks). Cheers, Moritz
