Is this normal?

Almost everyone thought because U was released there will be no more T builds. And the e/OS/Team surprised us.

@Manoj

We are putting out a v2.6.4 build specifically for devices which had a U build coming in v2.6.3
2.6.4 is a T or A13 build.
Moving forward we will again support multiple OS builds for devices instead of only one OS per device.
