5.4 betas work with 1.3.0, you will have to extract the plugin dlls to a slightly different path, ex: C:\Program Files\Unity 5.4.0b11\Editor\Data\VR\Unity\Win64 for the 64-bit windows OVRPlugin.dll. We will begin shipping the newer plugin in a future beta.
Oculus has not done as much testing on 5.4 beta builds so they are hesitant to recommend them for shipping products. But please do test them, they are fully compatible
