[WLANware] [ANNOUNCE] Gluon v2021.1.x End of life

[Andreas Ziegler]

The Gluon framework's v2021.1.x branch has reached its end of life.
You can find documentation about the release life cycle of the Gluon
branches on the GitHub Wiki [1].
We have stopped maintaining this branch and will not create a release 
based on it anymore.
Mentioned Gluon branch is based on the OpenWrt 19.07 branch which 
already reached its end of life in April 2022 [2].

Updating to the v2022.1.x release series is the recommended course of 
action, please take note of the corresponding release notes [3] [4].

The following is important information already provided with the 
v2020.2.x EOL announcement which is still relevant:
If your current release is older than v2021.1, please read the release 
notes of all releases starting with v2020.1 carefully as some deprecated 
features have been removed. We also introduced ways to deal with these 
feature removals.
Also note, that updates from before v2018.2 to v2021.1.x or newer are 
not supported.
You really need to do an intermediate update to a release based on the 
v2020.2.x branch, if you're still on firmware based on a release older 
than v2018.2.
Keep in mind that this also applies to devices that may not have been 
updated yet because of being offline or so. A solution may be to ship a 
new autoupdater-path with the v2020.2.x based release, so that older 
firmware releases will always do a two-step update. There are also 
communities using a new path for each major release to work around 
similar issues.
