As part of the usual manual process of creating the snapshot, we give the community a period of several hours to independently verify and validate the snapshot. For those with the developer skills and the knowledge about IOTA, you should make sure that your local database is at solid milestone 13157. Once you confirmed that, aggregate all transactions into their respective addresses and balances.
The official new snapshot can be found here: http://pastebin.com/rN2zyxw5. Further instructions will be provided in a couple of hours.
