20110613 was an update to apps. Namely an updated Vending.apk (Android Market) which supported in-app purchases. This meant that the Market no longer had to self-update after being initialized and then opened several times in order to provide support for apps which use in-app billing. It is only compatible with Android 2.3.4 and higher, due to API changes.
