Bug#529104: confluence: please upgrade your watch file
Your package ships a version 1 debian/watch file, but this is
deprecated and support for it is going to be removed soon from uscan.
It is strongly recommended that you rewrite it in the version 3
format, as described by uscan's man page, since it brings more
flexibility and support for it will not be dropped any time soon.
If you need help rewriting it don't hesitate to reply to this
message, or tag the bug as 'help'.
