Releasing version 8.1

Version 8.1 of has just been released. It is a bugfix release correcting a performance regression related to operations involving tz3 addresses and several compilation problems in some contexts.

Recall that version 8 of the node is the first version that can run protocol Edo. So, if Edo is activated, everybody would have to update to a node version 8 or higher. Moreover, our analyses show that the many “reorgs” occurring right now in mainnet are related to the fact that nodes running version 7 repeatedly try to compile protocol Edo and fail, since the beginning of the “testing” phase of the Edo vote. For these reasons, we advise deploying version 8.0 or higher now.

Full changelog and update instructions are available in the version 8 release page:

Note that the update includes some fixes that downgrade external dependencies. Consequently, when compiling from source, version 8.1 requires a different environment than version 8.0. In case this causes issues, we continue to provide the following alternatives: Docker images and a tezos package in the OPAM repository. In addition, we now provide static binaries for Linux in the release on GitLab!

The Git tag for this release is v8.1 and the corresponding commit hash is d74e7b6d763745f6d1b8a5fdf4ef9098268ebe7b . Branch latest-release now points to this new tag.
