The AT&T version of the LG G Flex is getting upgraded! Huzzah! But don't bust out the champagne just yet, G Flex owners: at the end of your upgrade you'll still be using Android 4.4.2, like you have been since April. According to AT&T's update support page, the newest patch for the phone doesn't add very much at all.
G Flex software build D95020f adds the "latest Android security patches," an updated version of LG's built-in music app that you don't use, and some compatibility fixes for the LG G Watch.
