Subject: Generate a versioned dependency for the GLib 2.86 transition
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~88^2~3
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=816fa364ba112b48f62f03ffa054cafd9bd14b76;p=gnome-shell.git

Generate a versioned dependency for the GLib 2.86 transition

GNOME Shell will need to be rebuilt after GLib 2.86 is uploaded to
unstable, so that its typelibs declare a dependency on GioUnix, which
they do not when built against older GLib. Generate a versioned
dependency so that this can be done via either a binNMU or a sourceful
upload.
