I’m running Windows 10 Pro v1803 with Local 2.4.2.
Since upgrading to 2.4.2, Local gives me a warning about shutting down my sites when my battery reaches 5% with over half my battery remaining and shows a notice that my sites will be shutting down automatically when my battery reaches 50%. At that time, nothing actually happens to my sites or Local, it’s just the message.
Not a big problem now that I know what’s going on, but it was definitely concerning the first couple times.
