A mysterious update for Chrome for Android just landed in the Market; at this point, though, it's not entirely clear what this update does, as a changelog is seemingly absent from the listing.

Update: Here's the changelog:

Chrome for Android Beta has been updated to 0.16.4215.215, picking up changes that have gone in through Chrome 16.0.912.77.  Beyond the Chrome changes, this update contains:

  • Android Beam support - now beam URLs from Chrome to other devices with NFC.
  • Support for additional countries
  • Compatibility checks to ensure system prerequisites for Chrome are met
  • Essential bug fixes

Known issues

  • 112923 : No way to toggle between mobile/desktop UA
  • 113140 : Youtube Links Do Not Prompt For Which Application to Use
  • 113132 : Chrome for Android beta doesn't support configured proxy in wi-fi settings
  • Other notable issues listed here

What we do know, however, is that the update brings Chrome up to version 0.16 and it appears to break support for devices running custom ICS builds (such as CM9). Otherwise, we're assuming the update offers the normal bug fixes and performance enhancements that we all gladly accept. Just after updating, the browser does appear to be a bit more snappy, but that could just be the placebo effect at work, considering details of the update's contents are absent.
