Samuli Piippo ee8b754f62 Update supported and tested Yocto versions
Update support table with Yocto 6.0 Wrynose, to be supported in dev
and lts-6.8. Remove styhead from CI builds as it's already EOL.
Qt 6.9 branch is now closed, no more changes accepted.

Pick-to: 6.10 6.8

Qt6 OpenEmbedded/Yocto Project layer
====================================
This layer depends on:
URI: https://git.openembedded.org/openembedded-core/
URI: https://git.openembedded.org/meta-openembedded/
Yocto version support
---------------------
The branching of meta-qt6 layer follows [Qt branching scheme](https://wiki.qt.io/Branch_Guidelines),
that is `dev` for the development branch, `6.x` for minor stabilization branches,
`6.x.y` for the release branches and `lts-6.x.y` for commercial LTS releases.
Each Qt release is tagged either as `v6.x.y` or `v6.x.y-lts`
Following table shows the Yocto releases which are used to test each
Qt version (x) and any additional Yocto releases that are stated in
the LAYERSERIES_COMPAT (c).
| Yocto \ Qt | dev | 6.10 | 6.9 | 6.8 | 6.7 | 6.6 | 6.5 | 6.4 | 6.3 | 6.2 |

Detailed status of supported Qt versions can be found from
https://doc.qt.io/qt-6/supported-platforms.html#supported-qt-versions
Commercial Qt
-------------
Qt is dual-licensed under commercial and open source licenses.
The license can be selected using the `QT_EDITION` variable. `commercial` and
`opensource` are valid values. The default value is `opensource`.
For commercial Qt users, the layer provides additional support with LTS
(Long Term Support) releases for selected Qt versions and additional
Qt modules licensed as commercial-only.
The LTS releases are available in branches named `lts-6.x`. The source code
for the LTS releases and the commercial Qt modules are only available for
commercial Qt license holders. They can only be built and used if you have
a commercial Qt license and you have set up SSH access to Qt Gerrit (see links below).
The commercial Qt modules are included in the build if the `QT_COMMERCIAL_MODULES`
variable is set to `1` and you are using a commercial edition of Qt.
QtMultimedia
------------
Qt Multimedia now prefers [FFmpeg][1] as the multimedia backend instead of GStreamer.
FFmpeg recipe, however, is flagged with LICENSE_FLAGS = "commercial", which means
that user must accept the license before FFmpeg can be used in the build. If user
accepts the license using LICENSE_FLAGS_ACCEPTED = 'commercial_ffmpeg', the FFmpeg
support is enabled in Qt Multimedia. If user doesn't accept the license,
Qt Multimedia only uses GStreamer.
