Ethereum Hard Fork?

I just heard about it, this morning (the 7th). Someone school me on what is going on. From what I could tell this doesn't seem to have the animosity between parties that the BCH/BSV fork did, so hopefully, it won't kill the market again, but I don't know much about it aside from the new chain being called Constantinople.

I thought it was the ETC hard fork on 11th?

I've done some more reading, and it seems like it's not a hard fork resulting in different coins, instead, essentially it is so many upgrades, that the blockchain is forking in order to be able to handle the upgrade...and I was all excited for free coins.

and yet last night cryptopia sent out email advising us we probably should withdraw our ETH into wallets we know the private keys for...

"If they have their ETH in exchange wallets then they will receive new coin if the exchange supports the respective hard forks. You can closely follow all the updates coming from the exchanges" - hmm, it is interesting, i need to check my exchanges concerning this fact
