This is the first stable release in the 1.12.x series. The major changes
in this series is the support for better control of sub-sandboxes, as
used by the steam flatpak.

In addition, this release fixes a security vulnerability in the portal
support. Some recently added syscalls were not blocked by the seccomp rules
which allowed the application to create sub-sandboxes which can confuste
the sandboxing verification mechanisms of the portal. This has been
fixed by extending the seccomp rules.
For details, see:

Other changes in this version:
 * Some test fixes
 * Update translations
 * Support for specifying the flatpak binary to use during exports
 * Install translations for all languages in the locale, not just the ones in
 * Fix progress reporting in flatpak fsck
 * Handle cases where /var/tmp is a symlink
 * Expose /etc/gai.conf to the sandbox
 * Fix the parental control checks for root
 * Handle missing /etc/ (musl)
