Ethereum
The planned roll-out date for ethereum's "Byzantium" upgrade is being postponed by just over a week.
The hard fork for Byzantium – the first leg in ethereum's Metropolis update – will now occur at block number 437,000,000, or about October 17 given current block production metrics. The original expected launch date was October 9, barring any complications during testing.

Intriguing post - thanks @varun16 .
