Hi, xfce 4.16 is around the corner (see https://wiki.xfce.org/releng/4.16/roadmap) and as usual i've been testing/packaging the various 4.15 dev releases (cf https://cgit.rhaalovely.net/xfce4/log/?h=next). Pre2 was released yesterday (per https://mail.xfce.org/pipermail/xfce-announce/2020-November/000926.html) so if people want to test it they're more than welcome to do so - packages are available via PKG_PATH=https://packages.rhaalovely.net/wip/amd64 and i've been using them for the past months.
this new version removes support for gtk2 everywhere, so orage will be removed and i'm working on a xfce4-mixer branch to directly support sndio without gst0.10. Landry
