HomePod devices are currently in the hands of Apple employees who are testing the smart speaker to iron out bugs before it becomes available for purchase later this year.
Apple previously released publicly available HomePod firmware in July, unwittingly leaking many secrets about the iPhone X. The HomePod firmware referenced the unreleased iPhone and confirmed its design and several features like Face ID facial recognition.
The update also highlighted details about the HomePod like its startup process and internal features that include display resolution and RAM.
This time around, there are no unreleased iOS devices coming in the immediate future so the new HomePod firmware is unlikely to be as exciting as the first, but it could potentially unveil new information about the HomePod itself as developers dig into the firmware code.
HomePod is Apple's Siri-based smart speaker that focuses heavily on high-quality sound. It incorporates a 7 tweeter array, an Apple-designed 4-inch upward-facing woofer, and an A8 chip to power features like spatial awareness.
When it launches this December, HomePod will be priced at $349.
