Version 9.0 contains a new version (V2) of the protocol environment, which is the set of functions that protocols can call. This new version is used by Florence, which is the current protocol on Mainnet. The release also contains Florence itself as well as its daemons (baker, endorser and accuser).
This release also contains the necessary configuration to join the
Florencenet test network, which runs Florence. To join Florencenet,
simply configure your node with
tezos-node config init --network
Version 9.1 fixes a performance and memory usage regression issue
Version 9.2 adds Granada, a protocol proposal for Mainnet featuring, among others, the Emmy* consensus algorithm, Liquidity Baking, and reduced gas consumption. Version 9.2 also improves how the mempool chooses which operations to keep. This should result in fewer endorsements being missed.
To update from sources:
git fetch git checkout v9.2 rm -rf _opam _build make build-deps eval $(opam env) make
If you are using Docker instead, use the
v9.2 Docker images of Tezos.
