Google has been making a lot of changes as of late and while we knew an update to Google Reader for Android was coming we didn't know when, exactly. The update has now landed though and with it also came an update to Google Docs.
For the most part -- Google Reader doesn't appear to of have changed all that much. Nothing like it's online counterpart that has seen some radical changes over the past few days love it or hate it. In this release you'll find left/right navigation and just visual changes for Ice Cream Sandwich and now rather then Google Buzz you have Google+ sharing options.
Google Docs however, has quite a few changes. You do get the visual changes that put it more inline with the look of Ice Cream Sandwich but you also get more optimizations for Honeycomb tablets, improved video playback as well as portrait and landscape modes. Information about your documents is now more easily found and sharing options have auto complete added as well. Both updates are available in the Android Market right now.
