OnePlus might not be the fastest manufacturer when it comes to updates anymore, but at least you can get your hands on new releases early, if you're okay with the occasional bug or issue. OnePlus' extensive Open Beta program lets owners participate in the software creation process, to an extent, and the latest phone to receive a new Open Beta version is the OnePlus 8T with version 4.
The new firmware introduces the April security patch — a bummer considering that the stable release will probably only roll out in May at best, when the April security update is already outdated. At least the rest of the changelog is packed with bug fixes and improvements across the board. The most notable ones are improvements for the always-on display that had issues with timely contextual information updates, a new data monitoring feature for OnePlus Games, and improvements to the camera.

In case you've been keeping count, OnePlus mostly skipped Open Beta 3 for the 8T. That's because the company noticed a few issues with the software, so it halted the rollout shortly after release. Open Beta 4 is safe to install from both Open Beta 2 and (for those who got the update) Open Beta 3. You should receive an OTA update when you're using either.
