        # We used `lerna publish --canary` option. However, since we now publish must version on branches,
        # i.e. v0.35.x branch, lerna fails to detect the latest version and publishes canary versions as
        # `0.34.0-dev.173+28e2c74cf0` instead of `0.36.0-dev.4+28e2c74cf0`, which creates confusion.

        #   lerna will link the dependencies of monorepo packages without ^ operator as npm
        #   is apparently bad at resolving ^ dependencies of the canary versions. For e.g
        #   @chainsafe/lodestar@^0.34.0-dev.4 resolves to => 0.34.0
        #
        # NOTE: Using --preid dev.$(git rev-parse --short=7 HEAD) results in `0.24.3-dev.3ddb91d.0+3ddb91d`
