Google Chrome for Android has been updated over Google Play, the first such update since Google's mobile browser exited beta at Google I/O back in June. There are no major feature additions in the new version 18.0.1025308, but there is a selection of fixes for "medium"-rated security issues, as well as stability fixes.
The new Chrome also seems a tad speedier on image-heavy sites like Android Central -- let us know in the comments if you're noticing the same effect.
If you're already running Chrome, head to the "My Apps" menu in the Google Play Store to grab the new update. If you're not, you can use the Google Play link above to jump straight to the latest version. Note that you still need to be on Android 4.0 Ice Cream Sandwich or 4.1 Jelly Bean to install Chrome.
