"This update for flatpak, libostree, xdg-desktop-portal,
xdg-desktop-portal-gtk fixes the following issues :

libostree :

Update to version 2020.8

  - Enable LTO. (bsc#1133120)

  - This update contains scalability improvements and
    bugfixes.

  - Caching-related HTTP headers are now supported on
    summaries and signatures, so that they do not have to be
    re-downloaded if not changed in the meanwhile.

  - Summaries and delta have been reworked to allow more
    fine-grained fetching.

  - Fixes several bugs related to atomic variables, HTTP
    timeouts, and 32-bit architectures.

  - Static deltas can now be signed to more easily support
    offline verification.

  - There's now support for multiple initramfs images; Is it
    possible to have a 'main' initramfs image and a
    secondary one which represents local configuration.

  - The documentation is now moved to
    https://ostreedev.github.io/ostree/

  - Fix for an assertion failure when upgrading from systems
    before ostree supported devicetree.

  - ostree no longer hardlinks zero sized files to avoid
    hitting filesystem maximum link counts.

  - ostree now supports `/` and `/boot` being on the same
    filesystem.

  - Improvements to the GObject Introspection metadata, some
    (cosmetic) static analyzer fixes, a fix for the
    immutable bit on s390x, dropping a deprecated bit in the
    systemd unit file.

  - Fix a regression 2020.4 where the 'readonly sysroot'
    changes incorrectly left the sysroot read-only on
    systems that started out with a read-only `/` (most of
    them, e.g. Fedora Silverblue/IoT at least).

  - The default dracut config now enables reproducibility.

  - There is a new ostree admin unlock `--transient`. This
    should to be a foundation for further support for 'live'
    updates.

  - New `ed25519` signing support, powered by `libsodium`.

  - stree commit gained a new `--base` argument, which
    significantly simplifies constructing 'derived' commits,
    particularly for systems using SELinux.

  - Handling of the read-only sysroot was reimplemented to
    run in the initramfs and be more reliable. Enabling the
    `readonly=true` flag in the repo config is recommended.

  - Several fixes in locking for the temporary 'staging'
    directories OSTree creates, particularly on NFS.

  - A new `timestamp-check-from-rev` option was added for
    pulls, which makes downgrade protection more reliable
    and will be used by Fedora CoreOS.

  - Several fixes and enhancements made for 'collection'
    pulls including a new `--mirror` option.

  - The ostree commit command learned a new
    `--mode-ro-executables` which enforces `W^R` semantics
    on all executables.

  - Added a new commit metadata key
    `OSTREE_COMMIT_META_KEY_ARCHITECTURE` to help
    standardize the architecture of the OSTree commit. This
    could be used on the client side for example to
    sanity-check that the commit matches the architecture of
    the machine before deploying.

  - Stop invalid usage of `%_libexecdir` :

  + Use `%(_prefix)/lib` where appropriate.

  + Use `_systemdgeneratordir` for the systemd-generators.

  + Define `_dracutmodulesdir` based on `dracut.pc`. Add
    BuildRequires(dracut) for this to work.

xdg-desktop-portal :

Update to version 1.8.0 :

  - Ensure systemd rpm macros are called at
    install/uninstall times for systemd user services.

  - Add BuildRequires on systemd-rpm-macros.

  - openuri :

  - Allow skipping the chooser for more URL tyles

  - Robustness fixes

  - filechooser :

  - Better support for snap and toolbox

  - Require `/usr/bin/fusermount`: `xdg-document-portal`
    calls out to the binary. (bsc#1175899) Without it, files
    or dirs can be selected, but whatever is done with or in
    them, will not have any effect

  - Fixes for `%_libexecdir` changing to `/usr/libexec`

xdg-desktop-portal-gtk :

Update to version 1.8.0 :

  - filechooser :

  - Return the current filter

  - Handle the 'directory' option to select directories

  - Only show preview when we have an image

  - screenshot: Fix cancellation

  - appchooser: Avoid a crash

  - Properly preview placement settings

  - Drop the lockscreen option

  - printing: Improve the notification

  - Updated translations.

  - settings: Fall back to gsettings for enable-animations

  - screencast: Support Mutter version to 3 (New pipewire
    api ver 3).

flatpak :

  - Update to version 1.10.2 (jsc#SLE-17238, ECO-3148)

  - This is a security update which fixes a potential attack
    where a flatpak application could use custom formated
    `.desktop` file to gain access to files on the host
    system.

  - Fix memory leaks

  - Documentation and translations updates

  - Spawn portal better handles non-utf8 filenames

  - Fix flatpak build on systems with setuid bwrap 

  - Fix crash on updating apps with no deploy data

  - Remove deprecated texinfo packaging macros.

  - Support for the new repo format which should make
    updates faster and download less data.

  - The systemd generator snippets now call flatpak
    `--print-updated-env` in place of a bunch of shell for
    better login performance.

  - The `.profile` snippets now disable GVfs when calling
    flatpak to avoid spawning a gvfs daemon when logging in
    via ssh.

  - Flatpak now finds the pulseaudio sockets better in
    uncommon configurations.

  - Sandboxes with network access it now also has access to
    the `systemd-resolved` socket to do dns lookups.

  - Flatpak supports unsetting environment variables in the
    sandbox using `--unset-env`, and `--env=FOO=` now sets
    FOO to the empty string instead of unsetting it.

  - The spawn portal now has an option to share the pid
    namespace with the sub-sandbox.

  - This security update fixes a sandbox escape where a
    malicious application can execute code outside the
    sandbox by controlling the environment of the 'flatpak
    run' command when spawning a sub-sandbox (bsc#1180996,
    CVE-2021-21261)

  - Fix support for ppc64.

  - Move flatpak-bisect and flatpak-coredumpctl to devel
    subpackage, allow to remove python3 dependency on main
    package.

  - Enable LTO as gobject-introspection works fine with LTO.
    (bsc#1133124)

  - Fixed progress reporting for OCI and extra-data.

  - The in-memory summary cache is more efficient.

  - Fixed authentication getting stuck in a loop in some
    cases.

  - Fixed authentication error reporting.

  - Extract OCI info for runtimes as well as apps. 

  - Fixed crash if anonymous authentication fails and `-y`
    is specified.

  - flatpak info now only looks at the specified
    installation if one is specified.

  - Better error reporting for server HTTP errors during
    download. 

  - Uninstall now removes applications before the runtime it
    depends on.

  - Avoid updating metadata from the remote when
    uninstalling.

  - FlatpakTransaction now verifies all passed in refs to
    avoid.

  - Added validation of collection id settings for remotes.

  - Fix seccomp filters on s390.

  - Robustness fixes to the spawn portal.

    (after transaction start)

  - Fix flatpak run handling of userns in the `--device=all`
    case

  - Fix handling of extensions from different remotes

  - Fix flatpak run `--no-session-bus`

    is done in the CLI commands.

  - Now the host timezone data is always exposed, fixing
    several apps that had timezone issues.

  - There's a new systemd unit (not installed by default) to
    automatically detect plugged in usb sticks with sideload
    repos.

  - By default the `gdm env.d` file is no longer installed
    because the systemd generators work better.

  - `create-usb` now exports partial commits by default 

  - Fix handling of docker media types in oci remotes

  - Fix subjects in `remote-info --log` output

  - This release is also able to host flatpak images on e.g.
