Not long after Sense 5.5 made its debut on the HTC One Max, the latest version of HTC's software is rolling out over the air to HTC Ones in parts of Europe. We've confirmed on our own device that the update is pushing out to unlocked Nordic handsets; HTC ROM-maker @LlabTooFeR tells us it's hitting Russia and Eastern Europe too. The update weighs in at a hefty 675MB and updates the HTC One to firmware version 3.62.401.1, based on Android 4.3 Jelly Bean and Sense 5.5.

As always, the update will likely take a few weeks to become available in all parts of Europe. HTC UK recently gave a three-to-five week estimate for bringing the Android 4.3 update to British HTC One handsets, so some users will be in for a longer wait than others.

The OTA upgrades international HTC Ones, previously on Android 4.2, up to the latest version of Jelly Bean, along with HTC's latest smartphone software. Sense 5.5 brings new features to BlinkFeed, including Google+, RSS and search support — and yes, the option to turn it off entirely. There's also a redesigned Gallery app with new video highlight templates and options.

All in all, this latest OTA puts international devices on par with the One Max, and slightly ahead of the U.S. and Canadian models, which have been getting Android 4.3 with Sense 5.0 in recent weeks. Check past the break for the official changelog and a handful of screenshots, and let us know in the comments if you're updating this morning.

Thanks, @LlabTooFeR!
