OnePlus 6 and 6T are now marked as EOL (End-Of-Life)
The unfortunate day has come. OnePlus now has announced on their forums that OxygenOS 11.1.2.2 was the last build released for the OnePlus 6 and 6T. Although OnePlus announced a new software maintenance schedule in July 2021 guaranteeing three major Android updates and four years of security updates to their flagship devices, it does not apply to devices released before 8-series. They instead follow its previous iteration: two years of major Android updates and an additional year of security only updates.

Considering the OnePlus 6 and 6T have been released in 2018, the software maintenance period is now over. OnePlus will not release any further builds for the devices.
We have reproduced below OxygenOS 11.1.2.2 changelog for reference.
System
- Improved system stability and fixed known issues
- Updated Android Security Patch to 2021.11
ZIPs were added in app as soon as rollout started and that their filenames were submitted to us, so you do not need to wait to install OxygenOS 11.1.2.2 if you're not already on it.
This is a sad day for 6/6T owners, especially as OxygenOS 11.1.2.2 has been released on December 3rd, 2021 with the outdated November security patch level. This means that a malicious application could prevent you from dialing 911 if the developer decides to register many PhoneAccount instances in order to trigger a bug (CVE-2021-39659) that has been fixed with January 2022 security patch level. While Google decided to provide an out-of-band update to Pixel 3 and 3XL to fix this specific bug (their last security update featured October 2021 security patch level), it appears that OnePlus isn't following this way, which is disappointing.
A device being end of life from a manufacturer point of view doesn't prevent you from using it anymore, but you may want to use custom ROMs such as LineageOS should you want updated Android security patches. Do however mind that flashing a custom ROM requires to unlock your bootloader and to wipe your device data.
