Yesterday, HTC's Mo Versi, the Vice President of Product Management, caused a few disgruntled sighs from the company's fans and One M7 owners by announcing that the two-year-old device wouldn't get any more major updates, including Android 5.1. That didn't apply to the Google Play Edition version of the M7, which is still set to get 5.1 in April.
But it looks like the replies Mo has received have elicited the company to take another look at the issue and consider changing its stance. Users argued that Android 5.1 isn't exactly a major update and that it brings a lot of bug fixes to Android, and HTC heard them. Mo explained that a lot of the 5.1 fixes have already been implemented in the M7's Lollipop 5.0 update, but told everyone to "stay tuned" nevertheless.
I heard you all on M7 5.1 for Carrier versions. Many of the fixes are already in our current SW, but understand your concerns. Stay tuned.

While HTC had promised to support the M7 for two years and that milestone was crossed, it is possible that the phone could get one more energy boost before it's relegated to the archives. Don't get your hopes up, but it's better to think that there may be a sliver of hope than none at all.
