Previously available for Preview members the latest March update for the Xbox One has started to roll out to the general public.
The update provides the ability to purchase Xbox 360 games from the Xbox One store (including easy access to Games with Gold Titles).
Another feature included is the option to quickly access your achievements via the OneGuide.
Additionally you can now broadcast party chat in Twitch (via the App) and the party chat will also support up to 16 players (previously 12); plus you can control the audio output of the chat i.e. direct it to your headset or speakers.
On top of this you can include party members on Windows 10 PCs in your Twitch broadcast.
Another feature is incorporated into the Avatars App, it basically allows you to compare friend's Avatar style/props. Thus if you see what you like you can equip a similar style to your own Avatar.
Xbox 'Record that'
However one of the best features for me is the ability to adjust the Xbox ‘Record that’ default time from 30 seconds up to 5 minutes. You can also get clips recorded at 15 seconds if needs be.
This way I can record ample footage without having to result in using a snapped GameDVR App or the latter taking up a good portion of the screen. Now I can simply use 'Record that', jump to another location in the game and do some more capturing. The upload studio editor can then be used to trim the footage back, so it provides a lot more control over the gameplay capturing process than before.

New Features Added Since Preview:
There are also a few new feature that have been introduced since the preview phase....
Xbox Elite Wireless Controller improved thumbstick precision with firmware update: Improvements were made to the behaviour of the Elite Controller’s thumbsticks, particularly when you are moving the thumbsticks diagonally. Microsoft have created a new method to calculate the position of the thumbsticks consistently, enabling thumbstick response that is more in line with what you are expecting. This method measures and uses the distance of the thumbstick position relative to the center focus point of the thumbstick base, instead of the standard method, which calculates the measurement using a two-dimensional plane. With the latest firmware update, you can expect increased accuracy of the thumbsticks on your Xbox Elite Wireless Controller for greater control.
Xbox Accessories app: The Xbox Accessories app on Windows 10 now includes a page displaying the current firmware version, battery status, and other details about the controller. This detailed information about the controller is already available on the app on Xbox One.
