These instructions assume that you are running Hermes v0.15.0. If you are running an older version, please refer the corresponding in reverse chronological order to update to v0.15.0 first and then follow these instructions.
From this version forward, all Hermes commands now use flags exclusively instead of positional arguments.
For example, in version 0.15.0 the create client command would be invoked
as follows to create a client on host chain ibc-0 which tracks reference chain ibc-1:
$ hermes create client ibc-0 ibc-1
As of version 1.0.0-rc.0, the command must now be invoked as follows, using flags instead of positional arguments:
$ hermes create client --host-chain ibc-0 --reference-chain ibc-1
Please consult the ADR which describes the new CLI flags for all commands.
The keys restore command has been merged into the existing keys add command.
Restoring a key now takes a file containing the mnemonic as input instead of directly taking the mnemonic.
Additionally, the flag to specify the key name for the CLI command keys add has been changed from --nname to --key-name.
As of version 1.0.0-rc.0, one must use the keys add command as follows in order
to restore a key from a mnemonic file instead of the keys restore command:
$ hermes keys add -chain <CHAIN_ID> --mnemonic-file <MNEMONIC_FILE>
The gas_adjustment setting has been deprecated in favor of new gas_multiplier setting.
If you were using the gas_adjustment setting, please remove it from the
chain configurations and use the gas_multiplier setting instead.
Whereas the gas_adjustment setting would specify a percentage by which to increase
the estimated gas amount before broadcasting a transaction (eg. a value of 0.1
would increase the gas by 10%), the gas_multiplier simply specifies by
which amount to multiply the estimated gas before sending a transaction.
For example, if the chain configuration used gas_adjustment = 0.1 to increase
the estimated gas amount by 10%, you must now use gas_multiplier = 1.1.
The query packet unreceived-packets has been renamed to query packet pending-sends to better
reflect its behavior.
The query packet unreceived-acks has been renamed to query packet pending-acks for consistency.
No breaking changes from v0.14.1.
No breaking changes from v0.14.0.
This release notably features a new query packet pending command to
list outstanding packet commitments that are either unreceived or pending
acknowledgement at both ends of a channel.
The create channel command now requires an existing client and connection,
unless the --new-client-connection flag is provided.
Please refer to the guide for more information.
Please refer to the CHANGELOG for older versions.
