Google this week quietly released Android 5.1 Lollipop, but the company didn’t make an announcement about it.

Users spotted 5.1 Lollipop on the Android One website in Indonesia. It’s listed multiple times on the site, according to Phonearena.com and Android Police.

Android Police posted photos of the upgrade.

On the site, the Nexian, Mito, and Evercoss phones are shown to have the OS. They’re all low-spec phones.

Last November, Google first rolled out Android 5.0 Lollipop for the relevant devices, including the Nexus smartphones and tablets. Like most OS upgrades, users reported problems, including battery issues.

Here’s a list of upgrades, according to Gotta Be Mobile:

Silent mode added after missing on Android 5.0
General improvements in system stability
Improved RAM management
Fixes for sudden app closures
Improved battery management
Excessive consumption of network devices when used Wi-Fi fixed
Issues with wireless connections fixed
Problems with Okay Google function solved
Notifications problems solved
Some sound problems experience by certain devices fixed
Other improvements and changes

And regarding upgrades to the Nexus devices, Android Police says:

I know, I know, you probably have Nexus questions at this point. When? What? Who? Where? I dug into our server logs to see whether this never-before-seen Android build LMY29F or its variants may have hit our site before and indeed found a whole bunch of them. All saying 5.1. All of them Nexus devices. We have:

Android 5.1; Nexus 5 Build/LMY29C
Android 5.1; Nexus 6 Build/LMY29C
Android 5.1; Nexus 6 Build/LMY29D
Android 5.1; Nexus 9 Build/LMY22E
Android 5.1; Nexus 6 Build/LMY22E
While these, of course, could have been easily faked, the amount of them and the presence of both the correct version number and the evolving build series make me confident that they’re real.
