The Ethereum update has officially happened, and so far, it seems to be going smoothly.
The fifth hard fork to occur on the second largest cryptocurrency has brought in a number of changes that are designed to improve the platform.

This round of changes, known collectively as Byzantium, is the first part of the long-anticipated Metropolis development phase. There is a second planned hard fork called Constantinople which is expected in 2018.
The price of ETH has remained relatively stable both before and after the fork occurred, reflecting the fairly uncontentious nature of the updates.

Not entirely smooth
Despite its uncontentious nature, Byzantium was the first major upgrade since the technology catapulted into the mainstream last year and was not without a few technical issues.
The last few days have seen the Byzantium enable software retracted a number of times due to critical bugs being found in the code. Although developers managed to get the corrections in place right on the deadline of when the hard fork was due to occur, there were serious thoughts about delaying the fork altogether.
It is important to note that all Ethereum clients need to upgrade if they want to avoid ending up stuck on an incompatible chain that is still governed by the old rules.
This will mean that there is no replay protection against the old network. Old clients will still be able to build transactions, but they will no longer be able to see what effects those transactions have.
