Hi Michael, We just did a major release to GSequencer v4.0.0 we migrated to Gtk4 and libsoup-3.0, thereby. https://savannah.nongnu.org/forum/forum.php?forum_id=10187 For webkit2gtk-4.0 we had a replacement to show the manual as PDF using libpoppler-glib. During transition, I had to disable webkit2gtk-4.0 in order to avoid symbols from libsoup-3.0 provided by webkit2gtk-4.1 Thank you for providing additional background. Thought, libsoup code is only reachable from the API. If you enable OSC Server in GSequencer you get SLIP encoded TCP/UDP stream. This is local only. http://krähemann.com/howtos/ags-osc-docs/index.html http://krähemann.com/api/libags/4.0.8/xml-rpc.html http://krähemann.com/api/libags-audio/4.0.8/audio-osc-over-xmlrpc-server.html The AGS-OSC-OVER-XMLRPC is rather esoteric and didn't manually test for a while. And I am missing a login controller. We do some sort of cookie based authentication and sessions. https://packages.fedoraproject.org/pkgs/gsequencer/gsequencer/ Fedora 35 didn't get the 4.0.x series release, I just ignored it. libsoup-2.4 really served its purpose. Had a lot of fun. regards, Joël On Thu, May 26, 2022 at 9:37 PM Michael Catanzaro <mcatanzaro@xxxxxxxxx> wrote: > > Hi developers, > > If you maintain a package that depends (directly or indirectly) on > libsoup, this mail is important. ***Lots of applications depend > indirectly on libsoup, even if you don't realize it!*** > > libsoup 3 (Fedora package: libsoup3) is incompatible with libsoup 2 > (Fedora package: libsoup).
