flyctl is updated almost every week, sometimes even once every one or two days. I checked the release notes of flyclt, and some updates only include some updates of upstream packages. Are these updates necessary?
If I don’t update flyctl for a month or two and use it, will there be any problems?
No need to worry. If you don’t update flyctl for a while, it’ll automatically update itself the next time you launch it. Just note that your command execution will be delayed until the update finishes.
