Version 7.0 notably introduces the multinetwork node.
Version 7.1 fixes a few compilation issues that users encountered with version 7.0, and fixes a few client commands.
Version 7.2 fixes an issue that could cause baking to fail when validating some smart contracts, and fixes how arguments are passed by the tezos-docker-manager.sh script when using Docker images.
Version 7.3 fixes a couple of security issues.
Version 7.4 adds the Delphi protocol and the Delphinet built-in network configuration.
To update from sources:
git fetch git checkout v7.4 make build-deps eval $(opam env) make
If you are using Docker instead, use the
v7.4 Docker images of Tezos.
New Versioning Scheme¶
Starting from this release, we are using a new versioning scheme to name our releases. Each release is now named “Version X.Y” where X is the major version number and Y is the minor version number. Minor releases mostly backport bug fixes into previous major releases.
Before releasing a new major version, we publish release candidates. For instance, before releasing 7.0 we published 7.0~rc1, the first release candidate for version 7.0. Once release candidates have been out long enough to be sufficiently tested and are considered stable, we publish actual releases. For instance, 7.0~rc1 was published April 15th 2020, and 7.0 was published May 5th 2020.
Additionnally, we provide a
latest-release branch which will always
be equal to the latest release. Release candidates are not considered
to be releases in this sense, so
latest-release will never
point to a release candidate. In other words,
to the latest stable release. Currently, it thus points to version 7.4.
If you are used to the
you can consider release candidates to be the new
branches, and the
latest-release branch to be the new
Note for Remote Signer Users¶
Note for users of
tezos-signer: the 7.0 (or above) client, baker, endorser
and accuser need the 7.0 signer (or above) to work. They are in particular not
compatible with the
mainnet version of
tezos-signer. So remember to
update your remote signer too!
The node can now be used with any network, including Mainnet (the default network) and test networks such as Carthagenet or even custom ones. See the Multinetwork Node documentation page for more information.
Thanks to this, the same release can be used for all networks
instead of having one branch per network. This allows to name this release
Version 7.0 instead of Mainnet April 2020, as releases are no longer tied to Mainnet.
If you are following the
mainnet branch, you should instead follow the

Changelog — Version 7.4¶
Added the Delphi protocol.
Added the Delphinet built-in network configuration. The alias to give to
Updated the list of bootstrap peers for Carthagenet.
Changelog — Version 7.3¶
Fixed a case where the number of open file descriptors was not correctly limited. This could result in the node crashing due to being out of file descriptors.
Set a limit to the length of some incoming messages which previously did not have one.
Fixed some value encodings which were missing cases.
Changelog — Version 7.2¶
Fixed an error that could cause baking to fail when validating some smart contracts.
Fixed an issue in
tezos-docker-manager.shwhich prevented to use some options, such as
Changelog — Version 7.1¶
Makefilenow ignores directories with no
lib_protocol/TEZOS_PROTOCOLfiles when listing protocols to compile. This fixes an error where
makecomplained that it had no rule to build

One can now use opam 2.0.0 again. In version 7.0, an error saying that it did not know about option
The repository no longer contains file names which are longer than 140 characters. Longer file names prevented users from checking out version 7.0 on encrypted file systems in particular.
Fixed an issue causing

Optimized the LAMBDA which is built when injecting manager operations.
Fixed a bug which caused the wrong entrypoint (
remove_delegate) from being used in some cases when setting delegates.
activate account ... withcan now be given a JSON value directly as an argument instead of only a filename.
Syntax for command

Changelog — Version 7.0¶
Node and client now come with all current and past protocols that are still in use on Mainnet or some active test networks.
tezos-node config initto select which network to connect to from a list of built-in networks (e.g.
carthagenet). If you do not run
config initor run it without the
--networkoption, the node will use the default network (Mainnet).
tezos-node snapshot importwhich causes the node to check that it is configured to use the given network.
networkconfiguration field to select which network to connect to, similar to
--network. This field also lets you specify an entirely custom, non-built-in network and is especially useful to run private networks. For instance, LabNet (https://forum.tezosagora.org/t/introducing-labnet-a-rapid-iteration-testnet-for-tezos/1522) uses such a custom configuration.
networkconfiguration field also allows to specify user-activated upgrades and user-activated protocol overrides. In the past, those upgrades and overrides required you to upgrade the node; now, you can just edit the configuration file instead. You can also disable built-in upgrades by specifying the configuration explicitly.
networkconfiguration field also allows to specify the parameters of the genesis protocol, such as the activation key of
proto_genesis. This allows to use the same genesis protocol for several test networks with different activation keys.
The network name is printed in the logs on startup.

/versionwhich returns the version of the node, the version of the P2P protocol, the version of the distributed DB, the commit hash and the commit date. Other RPCs which returned version numbers (
/monitor/commit_hash) are deprecated: use
RPCs which returned
completedfields now return durations (relative to the value of the
pushedfield) instead of timestamps.
Improved various log messages and errors.
Fixed a memory leak causing greylisted addresses to be stored several times unnecessarily.
Fixed a small memory leak causing each new worker to store a logger section name forever.
When exporting snapshots, you can now specify the block not only by its hash but also by its level or using an alias such as:
Fixed a bug which caused snapshots to fail if the checkpoint was a protocol transition block.
upgrade storage. This flag causes the node to tell you whether a storage upgrade is available.
Allow more files to exist in the data directory when starting a node from an empty storage:
peers.json. Before, only
Fixed a bug which caused the check of the
version.jsonfile to be performed incorrectly.
The external validator process now dynamically loads the new protocol after a protocol upgrade.
Sandbox mode may now be used with the external validator process. Before, it required
The mempool RPC for preapplication now actually sorts operations when the flag is set.
Changed the format of the peer-to-peer protocol version number. Nodes which are running a version older than Mainnet December 2019 can no longer connect to nodes running this new version and should upgrade.
Added new peer-to-peer message type: Nack, that carries a list of alternative peers and can be returned by nodes with no room for your connection.
If maximum number of connections has been reached, before rejecting peers, authenticate them and memorize their point information.
Improved the behavior of the greylist of peers.
The node is now capable of recovering from some cases of storage corruption that could in particular occur if the disk became full or if the node was killed.
Fixed a bug which caused the peer-to-peer layer to send the wrong acknowledgement message in response to swap requests.
Nodes built for Docker images should now correctly contain the version number.
Removed non-read-only Babylon client commands as they are no longer useful.
If the node connects to a peer of another network (e.g. if a Mainnet node connects to a Carthagenet node), it now removes this peer from its list of known peers. This in particular means that it will no longer advertize this peer or try to connect to it again.
In private mode, do not try to discover the local network peers as they will not be trusted anyway.
Fixed a bug which caused the node to stop with a segmentation fault.
Added protocol command
expand macros into expand macros in Michelson code.
tezos-admin-client protocol environmentwhich displays the version of the environment used by a given protocol.
Greatly reduce the time the client takes to load.
--mode mockupwhich can be used to run client commands, such as commands to typecheck Michelson code, without a running node.
create mockup for protocoland
list mockup protocolsto manage mockup environments used by
Multisig commands can now be used both with contract aliases and addresses instead of only with aliases.
Added a timeout to signature operations using a remote signer, which could otherwise block the baker, endorser or accuser.
Added safety checks against code injection when compiling downloaded or injected protocols. This was mostly a security concern for nodes with publicly available RPCs.
Added new demo protocol:
Prepared the shell to be able to handle multiple protocol environment versions.
