Back in January, Microsoft revealed that it was planning on making it easier for those enrolled in the Windows 10 Mobile Insider Program to receive firmware updates. At the time, the workaround was to switch to the Production ring (turn off Insider builds), install the firmware update, and switch back to whichever ring the user was on.
As of tomorrow, users will be able to grab those firmware updates without switching rings, which was the plan from the start. This begins on March 3 at 10 AM PST.
The firm also announced a new firmware update for select Lumia 950 models. You can find the list right here. Spoiler: the AT&T model still isn't on it.
Insiders that want the firmware update can switch to the Production ring to get it, or they can wait until tomorrow and update their device directly.
