Version 11.0 contains a new version (V3) of the protocol environment, which is the set of functions that protocols can call. This new version is used by protocol Hangzhou, which is a proposal for the successor of Granada, and by Hangzhou2, which is a modified version of Hangzhou with a number of critical bug fixes. This release candidate also contains Hangzhou2 itself as well as its daemons (baker, endorser and accuser).
Version 11.0 contains a user-activated protocol override from Hangzhou to Hangzhou2 on Mainnet. This means that nodes using version 11.0 (more precisely 11.0~rc2 and later) will activate Hangzhou2 instead of Hangzhou if Hangzhou was to be activated by the on-chain governance process.
Version 11.1 fixes some storage issues, as well as some build issues.
To update from sources:
git fetch git checkout v11.1 rm -rf _opam _build make build-deps eval $(opam env) make
If you are using Docker instead, use the
v11.1 Docker images of Tezos.
If you are installing Tezos using Opam, note that the required
OCaml version is now 4.12.1. This means that you need to create a
new switch with
opam switch create 4.12.1 before you run
opam install tezos.
