Trying to remember all the reviews I just sent for this series, there
was not a single case which absolutely requires bumping the version
here.

Not bumping the version would be very attractive, because it would let
wider choice between Gtk+ etc. versions for people who do already rely
on xdg-shell working. (Even if you might claim they shouldn't, but they
do.)

Is it reasonable to expect that nothing will seriously break if we
don't bump the version, and people mix and match implementations before
and after this patch series?

I do not care about build failures, those are easily patched, and I
assume projects carry their own copies of xdg-shell.xml anyway, so
upgrading means work in any case. All I care is the "binary"
compatilibity. Like said, changing error codes is also not a reason,
because errors are fatal anyway.

If you do see the need for bumping the version, I really really hope we
can get it in before 1.8-alpha. It's such a big breakage, that I'd hate
to do it later when we are trying to stabilize a Weston release.

Sorry for getting here sooner.


To anyone wondering: xdg-shell uses a special experimental versioning
scheme, where every bump literally breaks everything. It is not
following the normal Wayland interface versioning rules yet, and
likely won't be for quite a long time.


Thanks,
