Google announced Project Treble last year as a way to make it easier for manufacturers to update their devices. It is supposed to reduce the duration between the launch of a new version of Android and when the update becomes available for a phone. It has also found usefulness by custom ROM makers who can now quickly whip up custom ROM versions (Generic System Image) of the latest version of Android in such a short time.
While Google has made it compulsory for all devices launching with Android Oreo and above to have Project Treble support right out of the box, some manufacturers have decided to not include it when updating older devices to Android Oreo since the latter isn’t compulsory.
Last year, OnePlus announced that its current phones(OnePlus 3/3T, OnePlus 5/5T) would get updated to Android Oreo but won’t support Project Treble which caused fans to launch a petition. Two months ago, the OnePlus 5 and OnePlus 5T devices running OxygenOS open beta received Project Treble support.
If you own the OnePlus 5 and OnePlus 5T, then you should know that the latest stable version of OxygenOS (version 5.1.5) brings full Project Treble support. The changelog doesn’t actually mention it but you can confirm by installing one of the numerous apps on the Play Store such as Treble Checker to know if it does. Those who have received the update have already confirmed it.

What the changelog of the new update does mention is August’s security patch and the ability to confirm your phone’s PIN code without tapping the check button. The update is about 1.6GB in size and is rolling out in batches, so be patient if you haven’t received it.
With Project Treble now available, security updates should arrive faster and owners should even receive Android Q when software support ends.
