Libpng is due to security issues: commit a5073ad9289f7e05ef38d2ce99dc71e91983b434 Author: Michael Natterer <mi...@gimp.org> Date: Mon Oct 31 09:36:15 2016 +0100 configure.ac: require libpng 1.6.25 Addresses bug #765850, and probably avoids a gazillion of vulnerabilities in the versions since the ancient 1.2.37 we required before. For libcms2 this is due to some rounding errors that affected some blending modes in gimp: commit 0ce364ee4dd2200e6607a4575af0cc657600afc9 Author: Michael Natterer <mi...@gimp.org> Date: Thu Sep 15 12:52:20 2016 +0200 configure.ac, app: require liblcms2 >= 2.7 and add an lcms2 runtime version check to app/sanity.c Fixes: Bug 736701 - LCMS2 rounding errors cause problems with certain GIMP blend modes I hope this helps, Simon -- si...@budig.de http://simon.budig.de/ _______________________________________________ gimp-developer-list mailing list List address: gimp-developer-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list List archives: https://mail.gnome.org/archives/gimp-developer-list
