Google has officially confirmed the Android 4.4.3 update, by posting a few factory images and binaries. The update is being rolled out to US' T-Mobile subscribers who own the Google Nexus 4, 5 or 7, starting June 2.

Google has posted Android 4.4.3 images for the Nexus 5, Nexus 7 (2013) WiFi, Nexus 10, Nexus 4, and Nexus 7 (2012) WiFi and Mobile. The Nexus 5′s Android 4.4.3 will be build KTU84M, while the rest will see KTU84L. Check out the factory images for Nexus devices and binaries.

The Android 4.4.3 brings security enhancements and various bug fixes. One of the first change spotted in the new update is the new skinned dialer that is little lighter themes than in builds below 4.4.3. It may be recalled Google had already shown the new dialer, when its official @GoogleNexus Twitter account inadvertently leaked the dialer back in April.
