[Freedesktop-sdk] Freedesktop SDK 21.08.0 has been released!

[Javier Jardón]

Hi everyone,

We have now released Freedesktop SDK 21.08.0. It is already available
on Flathub!

Check the NEWS file for all the updates: [1]

If you maintain an application using the Freedesktop SDK runtime, please
consider upgrading the version, especially if you are still using
19.08 or earlier as It's going to be EOL soon [2].
In most cases, this mostly requires changing "runtime-version"
in the Flatpak builder manifest of the application.

This is the result of a year of work from all our contributors, thanks
a lot to all of them! (including our beloved freedesktop-sdk bot :)):

And thanks to our infrastructure sponsors; without their help this
project will not be possible:

- https://www.worksonarm.com/ (ARM build servers)
- https://osuosl.org/ (x86_64 build servers)
- https://fosshost.org/ (server infrastructure)

Also, special thanks to Codethink [3] for sponsoring the time to add
RISC-V support!
You can see the talk Valentin did about this in LAS here: [4]
