A desktop PiggyBank update is available — version 1.2.1.1. This fixes some minor but important issues from the first release of PiggyStakes (v1.2.0). You should upgrade to 1.2.1.1 as soon as you can; older clients will eventually be cut off the network.

Mac users, a Mac release is coming in mere days. Please do not stake until then!
