GL-B1300 Mesh Support on 4.3.10

Is mesh supported for the GL-B1300 on firmware 4.3.10? The release notes don’t say either way. I have 3 GL-B1300 devices. I upgraded them all to the latest firmware and notice that the mesh buttons don’t seem to trigger the led flashing. So was wondering if it is still supported and if so how to get it configured.
