According to the official Drive Google+ page, the Android client for Google's cloud-based file and document manager will be receiving an update "over the next few days" adding new, richer editing features, as well as a few smaller feature tweaks. It looks like a lot of these features have already been available on the version of Drive that shipped with KitKat (1.2.403.9), though the one rolling out today is even newer.
Google specifically mentions search - a big must-have that the mobile app has been lacking - as well as search and replace, inserting / managing tables, and named styles as some of the new editing tools that will be included in the new version of the app.
In addition, there are a few slightly less noteworthy changes to look out for. You can now rename your scans before they get uploaded to Drive, view your files in a two-column layout on your tablet, and sort your files by quota used.
Something we also noticed that wasn't mentioned by the announcement is the used/total quota in the slide-out navigation.
If you're not into the whole "waiting" thing, though, we've got you covered with the APK download of the new version (1.2.461.14), which you can grab below.
The APK is signed by Google and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for Google to push this download to your devices, which can take days, download and install it just like any other APK.
File name: com.google.android.apps.docs-1.2.461.14.apk.
Version: 1.2.461.14 (for Android 2.3+).
