Unfortunately, as we move further away from the release of a phone, the vendor provides less and less support until they finally stop providing any updates.
We have reached that point late last year for the Google Pixel 4 and as such, WundermentOS will move into a deprecated state for this device as of next months security patches.
What does that mean?
- Builds will continue to be created for the device, but without vendor support, no new security patches for the proprietary blobs will be included.
- Builds will continue to include security updates that are published in the monthly AOSP security bulletins.
- Future major updates (like to Android 12) may or may not become available depending upon LineageOS support for those updates as well as if they are secure (aka SELinux enforcing enabled).
- Installation guides and videos will not be updated.
So what should you do? If possible, upgrade your phone to a newer device that continues to be supported by the vendor.
Also, checkout out the WundermentOS device retirement policy page to see when builds might end in the future.
