Well this is a pleasant surprise. The mid-range LG G Stylo and LG Leon both appeared on T-Mobile's lineup just a couple of months ago, and now they're getting their first significant updates. Significant in fact because they're coming to the very latest public build of Android. T-Mobile's support pages for both phones were updated this morning telling users to expect an over-the-air update to Android 5.1.1. Both phones (also somewhat surprisingly) ran Lollipop 5.0 when they first launched on the US carrier.
