What's a "big change". Multisig, segregated witness and the lightning network all came in after Satoshi had disappeared so yes it did.

Is the Lightning Network part of the Bitcoin protocol? No.
I do not mean BIP updates or soft fork rather a change from what bitcoin was.

I'll give some quotes to clarify what I mean.

On July 29 2010, it was discovered that block 71036 contained several transactions with a ton of OP_CHECKSIG commands. There should only ever be one such command. This caused every node to do extra unnecessary work, and it could have been used as a denial-of-service attack. A new version of Bitcoin was quickly released. The new version did not cause a fork on the main network, though it did cause one on the test network (where someone had played around with the attack more).

seems a block at height 74638 has expoited a bug in the net. It uses an integer overflow to make a negative total transaction. The two transaction outputs are:

out Value:92233720368.54(7ffffffffff85ee0) out Value:92233720368.54(7ff
ffffffff85ee0)

We need a fix asap
