The latest Google Wallet app update has hit the Play Store. Essentially, this brings the Play Store version of the Wallet up up to what Nexus 5 users had, at least feature wise. The version numbers are different. The Nexus 5 has Wallet version 2.0-R137-v13-RELEASE while the new Play Store version is coming as 2.0-R133-v14-RELEASE. Version number specifics aside, Google has also updated the support page with mention of Kit Kat.
