If this is an actual update , it is most likely specific shipping dates for the first wave of L5 s I imagine. I really hope they got that overheating issue resolved because I dont see that as a minor problem the device should be shipped with .
I couldnt imagine Purism would ship with a device that overheats and throttles to 1% indicating a serious thermal overload. I definitely dont want to find out I have a Samsung Galaxy Note 7-esque grenade in my pocket.
So Im cautiously optimistic this was resolved or atleast has been mitigated to a level that will be completely resolved in OTA updates.
