# 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
- 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.
## 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.
