Bug#864028: unblock (pre-approval): flatpak/0.8.5-3

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock

I would like to update flatpak in stretch along the upstream 0.8.x branch,
either for stretch r0, or if it's too late for that as an update via
stretch-p-u for r1.

The upstream developer is planning to release 0.8.6 at some point in the
near future, but for now here is an unblock request for the patchset that
would be in 0.8.6 if it was released today.

In particular this version adds fixes needed by sandboxed Spotify and
sandboxed KDE apps, strengthens the sandbox by limiting the integration
files that get exported, and adds the ability to do semi-automatic key
rollover and location migration.

If you have any feedback that you would like me to pass to upstream
(in particular if there are any changes that you feel are not sufficiently
conservative) please let me know.

Thanks,
