For those on the Priv Beta program, there is a new Beta software update available for most devices. AT&T users get update AAG873 while those on unlocked devices get version AAG853.
The update contains the October security updates and most likely other bug fixes and optimisations. No changelog was given for any changes but the update is around 157mb.
No mention of a beta update for the DTEK50 as yet but I’d imagine this would be released shortly. So if you’re in the Beta program, check for the update by going to Settings/About Phone/System Updates to see if it is available for you.
