0.3.4 hotfix build is ready. It adds new hardened checkpoint at block #13560.

If you don’t have problem, which is described below, you can ignore this. But anyway, it’s recommended to apply this update, especially if you running mining pool or another service. It will prevent downtime possibility.

If you see “Invalid checkpoint found” message and your client switches to safe mode, you need to install this update and re-download the blockchain. By the way, with win32 client you don’t need sync og the whole blockchain, you can use files from the blockchain snapshot.
