If you have an international, unlocked version of the HTC One, then an update to Android 4.3 which includes Sense 5.5 could be rolling out to you shortly.
Several sites are reporting that the 675MB update is now hitting HTC One owners in European countries in Nordic regions as well as Russia and countries in Eastern Europe.

As usual for Australian Carrier branded HTC one handsets, the wait now begins. Optus has updated their software update page with details on the 4.3 update arrival, advising that the next update will be for Android 4.3 with an expected release in early November. Both Telstra and Vodafone have not listed any information about the update in their recent software update posts.
