Facebook has been making several improvements to its app in regards to photo sharing and uploading, and this latest update continues that trend. The changelog is just three bullet points. First, photo tagging has been improved to be faster. Second, you can now choose an album when uploading photos -- no more mashing everything into a "mobile uploads" album. Lastly, there is a bug fix related to photos not uploading for users with certain languages (although they're not listed).
If you're not one of the billion people using Facebook regularly (over half primarily on phones) and have yet to install the app, maybe now is the time to at least take a look. You can grab it at the Google Play Store link above.
