Version 7.1

Source Compilation

  • The Makefile now ignores directories with no lib_protocol/TEZOS_PROTOCOL files when listing protocols to compile. This fixes an error where make complained that it had no rule to build TEZOS_PROTOCOL for directories that Git does not completely remove when switching branches.

  • One can now use opam 2.0.0 again. In version 7.0, an error saying that it did not know about option --silent was emitted.

  • 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 make build-deps to sometimes fail after an update of the digestif external library.

Client

  • Optimized the LAMBDA which is built when injecting manager operations.

  • Fixed a bug which caused the wrong entrypoint (set_delegate instead of remove_delegate) from being used in some cases when setting delegates.

  • Command activate account ... with can now be given a JSON value directly as an argument instead of only a filename.

  • Syntax for command call from <SRC> to <DST> has been fixed to match the one for proto_alpha. It should now be called as call <DST> from <SRC>.

Version 7.0

Multinetwork

  • Node and client now come with all current and past protocols that are still in use on Mainnet or some active test networks.

  • Added option --network to tezos-node config init to select which network to connect to from a list of built-in networks (e.g. carthagenet). If you do not run config init or run it without the --network option, the node will use the default network (Mainnet).

  • Added option --network to tezos-node run and tezos-node snapshot import which causes the node to check that it is configured to use the given network.

  • Added network configuration 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.

  • The network configuration 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.

  • The network configuration 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.

Node

  • Added RPC /version which 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 (/network/version, /network/versions and /monitor/commit_hash) are deprecated: use /version instead.

  • RPCs which returned treated and completed fields now return durations (relative to the value of the pushed field) 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: caboose, checkpoint, save_point or head.

  • Fixed a bug which caused snapshots to fail if the checkpoint was a protocol transition block.

  • Added --status flag to 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: version.json, identity.json, config.json and peers.json. Before, only identity.json was allowed.

  • Fixed a bug which caused the check of the version.json file 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 --singleprocess.

  • 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.

Client

  • Added protocol command expand macros in to expand macros in Michelson code.

  • Added command tezos-admin-client protocol environment which displays the version of the environment used by a given protocol.

  • Greatly reduce the time the client takes to load.

  • Added option --mode mockup which can be used to run client commands, such as commands to typecheck Michelson code, without a running node.

  • Added commands create mockup for protocol and list mockup protocols to manage mockup environments used by --mode mockup.

  • 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.

Protocol

  • 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: proto_demo_counter.

  • Prepared the shell to be able to handle multiple protocol environment versions.

Docker Script

  • Renamed script alphanet.sh into tezos-docker-manager.sh. You should still use mainnet.sh and carthagenet.sh as they are now symbolic links to tezos-docker-manager.sh instead of alphanet.sh.

  • Removed script zeronet.sh as Zeronet is using an older version of Babylon (PsBABY5H) for which the baker, endorser and accuser binaries are no longer available. If you need to connect to Zeronet, use the zeronet branch instead, which still has the zeronet.sh script.

Miscellaneous

  • Remove outdated nginx.conf.
