Sigma Firmware update on many lenses relating to T6i, and T6s live view performance

From Sigma:

Notice to our Canon mount lens users:

Thank you for purchasing and using our products.

We have found that Live View Mode cannot be used on the EOS 8000D (Rebel T6s / 760D) and EOS Kiss X8i (Rebel T6i / 750D) released on April 17th 2015 by Canon Inc. with some of SIGMA’s Canon mount interchangeable lenses. For those who own the lenses, we are going to provide a firmware update free of charge.

PhenomenonWhen the Live View Mode button on the camera body is pressed, the operation stops without displaying images on the rear LCD monitor.

I was considering picking up a t6s but with the 50-150 OS being effected I might rule it out. Nice that sigma is offering firmware updates but sending lenses in is never fun!
