Past Tezos Amendments
A list of past successful protocol upgrades and their features.
Athens was the first proposed protocol amendment for Tezos. Two proposals - “Athens A” and “Athens B” were injected by the development team, Nomadic Labs in February 2019.
Of the two proposals, Athens A sought to increase the gas limit and reduce the roll size required to bake from 10,000 tez to 8,000 tez. Athens B sought to just increase the gas limit. Athens A was autonomously activated onto the protocol in May 2019.

Notable changes included a new consensus algorithm variant (Emmy+), addition of new Michelson features to aid smart contract developers, an account rehaul that enabled clearer distinction between tz and kt accounts, as well as refinements to the quorum formula and addition of a 5% proposed quorum threshold.
