Android Wear got bumped up to version 2.6 with several helpful improvements. The Recent App complication is handy for multitasking and Google improved touch algorithms to reduce the chances of accidental side-swipe and long-press gestures.
Reading text on the tiny watch screens will be a bit easier now. The font size changes depending on message length, which should give you an extra line of text.
You also get a better view of what the mobile connections are doing. Swipe down in Quick Settings to check Wi-Fi, Bluetooth and cell connection status. Theres also a download progress indicator in the notifications.
