I can confirm new binaries appear to have stabilized the chain. Wallet is working very nicely as well. Thumbs up to the Factom devs.
I've had the new chain working for approx 36 hours without a glitch and shifting coins around addresses created with different seeds. It all looks very good.
There are a number of companies POC in sandboxes at the moment, so this should mean some of them can move to the live chain. This should mean M2 is up and running provided the syncing of the chain holds.
