Hermes v1.4.0 brings compatibility with chains based on Tendermint/CometBFT 0.37, while retaining compatiblity with Tendermint/CometBFT 0.34. This is transparent and does not require any additional configuration.
The relayer now supports ICS consumer chains, which only requires operators
to specify the unbonding_period parameter in the chain settings. This is only
a temporary requirement, in the future Hermes will seamlessy support consumer
chains with minimal changes to the configuration.
This release also deprecates support for chains based on Cosmos SDK 0.43.x and lower, and bumps the compatiblity to Cosmos SDK 0.47.x.
The relayer now also allows operators to filter out packets to relay based on whether or not they contain a fee, and the minimal amount of such fee. Please check the relevant documentation in the Hermes guide for more information. Additionnaly, Hermes now also tracks metrics for ICS29 fees.
This release includes a new query client status CLI to quickly check whether a client is active, expired or frozen.

The ibc and ibc-proto crates
have been split into their own repositories under
the cosmos organization.
Moreover, Forcerelay will not be using the original ibc crate anymore,
and will from now on use instead the ibc-relayer-types crate, which is a
trimmed down version of the ibc crate that contains only the data structures used by Forcerelay.
This change does not impact end-users of Forcerelay, but may affect downstream
consumers of the ibc-relayer library in some cases.
Please reach out to us if you encounter any issue following from this reorganization of the repository.
The gm binary has been split out of the repo and has been moved into its own repository.
This change doesn't affect current local instances of the gm binary,
though new versions will need to be sourced from the new repository by running
git clone informalsystems/gm and running the install script from there.
For more information, see this section of the Forcerelay guide.

After more than 2 years in the works, this is the first stable release of the Forcerelay relayer! 🎉
For reaching this milestone, we thank the valuable contributions of over 50 individuals, spread across more than 800 documented & resolved issues. Beside Cosmos-SDK and Tendermint, we are fortunate to maintain some of the most active and intense repository in the Cosmos ecosystem. Most importantly, we thank the relentless work of relayer operators that have already relayed billions worth of value in IBC production networks, and have provided us with invaluable feedback on improving Forcerelay and raising the overall stability of IBC. Kudos to everyone!
⚠️ If upgrading from Forcerelay v0.15.0, be aware that this release contains multiple breaking⚠️ changes to the Forcerelay command-line interface and configuration.⚠️ Please consult the UPGRADING document for instructions for more details.

- Added many new metrics to the telemetry. The full list can be found in new the guide section linked above
As of v1.0.0-rc.0, the Forcerelay CLI is now versioned separately from
the other crates in the project. As such, the top-level version
designates the version of the Forcerelay CLI, but the other crates in
the repository do not necessarily match this version. For example,
the ibc and ibc-relayer crates are released under version 0.19.0
for Forcerelay v1.0.0.
The structure of this changelog has therefore changed as well, changes are now grouped first by crate and then by the type of change, eg. feature, bug fix, etc.
The release notes below only contain the changes introduced since v1.0.0-rc.2. For the full list of changes since v0.15.0, please consult the sections below for v1.0.0-rc.2, v1.0.0-rc.1 and v1.0.0-rc.0.

Forcerelay v0.13.0 improves performance by lowering the pressure on the full nodes by adding a caching layer for some queries. It also fixes a bug which could cause an exponential slowdown when relaying between many chains with a low average block time.
This release also add support for wildcards in port and channel identifiers in the packet filter configuration, which enable operators to filter ICA channels based on the port prefix.
Additionally, the IBC Protocol Buffers definitions can now be used from CosmWasm.
As of version 0.13.0, Forcerelay supports relaying on Interchain Accounts channels.
If the packet_filter option in the chain configuration is disabled, then
Forcerelay will relay on all existing and future channels, including ICA channels.
There are two kinds of ICA channels:
- The host channels, whose port is
icahost - The controller channels, whose port starts with
icacontroller-followed by the owner account address. See the spec for more details.
If you wish to only relay on a few specific standard channels (here channel-0 and channel-1),
but also relay on all ICA channels, you can specify the following packet filter:
Note the use of wildcards in the port and channel identifiers (
['ica*', '*']) to match over all the possible ICA ports.
[chains.packet_filter]
policy = 'allow'
list = [
['ica*', '*'], # allow relaying on all channels whose port starts with `ica`
['transfer', 'channel-0'],
['transfer', 'channel-1'],
# Add any other port/channel pairs you wish to relay on
]If you wish to relay on all channels but not on ICA channels, you can use the following packet filter configuration:
[chains.packet_filter]
policy = 'deny'
list = [
['ica*', '*'], # deny relaying on all channels whose port starts with `ica`
]This information can also be found in the Forcerelay guide.

This release notably brings compatibility with Cosmos SDK 0.45 and IBC v3.0.0-rc.0,
as well as support for non-standard ports in the channel handshake.
It also contains a fix for a bug where SendPacket events were duplicated when emitted at EndBlock,
and fixes another bug where Forcerelay would clear packet at startup even when clear_on_start = false.
The relayer will now also honor the tracing filter specified in the RUST_LOG environment variable, if any.
As of this release, the relayer will not respond to the SIGHUP signal and will therefore
not reload the configuration anymore. This feature has been deemed unnecessary given the
recent performance improvements, and it is now recommended to just restart the relayer
when the configuration is updated.
Additionally, a new CLI command clear packets
has been added for clearing packets in both direction on a given channel.

adds options to the create client command to customize the client parameters,
makes the deposit denomination configurable in tx raw upgrade-chain via a new --denom flag,
and adds a completions CLI command to generate shell auto-completion scripts.
This release includes a breaking change, which requires the configuration file to be edited.
The mode.packets.filter configuration option has been removed and is now enabled by default.
Before running Forcerelay v0.11.0, make sure you remove the mode.packets.filter option from the configuration file.

This release notably updates the underlying CLI framework (abscissa) to version 0.6.0-beta.1,
which now uses clap for parsing command line arguments. This substantially improves the UX of the CLI,
by adding support for --help flags in subcommands and improving help and usage printouts.
The --version option of the create channel subcommand has been renamed
to --channel-version, with the old name still supported as an alias.
Additionally, the -h short flag on many commands is now -H to avoid
clashes with the clap-provided short flag for help.
This release also improves the handling of account sequence mismatch errors, with a recovery mechanism to automatically retry or drop tx upon such errors.
The relayer now also supports dynamic versions in channel open handshake (which is needed by Interchain Accounts), and enables full support for IBC v2.

This release requires operators to update their Forcerelay configuration.
The mode configuration section now replaces the strategy option.
If Forcerelay was configured with strategy = 'packets', then the configuration needs to be changed in the following way:

log_level = 'trace'
-clear_packets_interval = 100
-tx_confirmation = true

+clear_interval = 100
+clear_on_start = true
+filter = false
+tx_confirmation = trueIf Forcerelay was configured to complete connection and channel handshakes as well, ie. with strategy = 'all',
then on top of the changes above, mode.connections.enabled and mode.channels.enabled must be set to true.

This is the final release of version 0.8.0, which now depends on the official releases of the prost and tonic crates.
In addition to everything that's included in v0.8.0-pre.1, this release updates the minimum supported Rust version to 1.56,
and contains various bug fixes and performance improvements which make the relayer more reliable.
A new setting was added to the Forcerelay configuration: max_block_time.
This setting specifies the maximum time per block for this chain.
The block time together with the clock drift are added to the source drift to estimate
the maximum clock drift when creating a client on this chain.
For Cosmos-SDK chains a good approximation is timeout_propose + timeout_commit

This is a pre-release which depends on in-house forks of various Rust libraries.
As such, it is advised to avoid depending on the ibc and ibc-relayer crates
at version 0.8.0-pre.1.
Forcerelay v0.8.0-pre.1 is considered stable and it is recommended for all users to update to this version.
This release notably includes a new memo_prefix configuration option
for specifying a prefix to be included in the memo of each transaction submitted
by Forcerelay.
Moreover, Forcerelay is now able to handle SendPacket events originating from Tendermint
ABCI's BeginBlock and EndBlock methods (#1231).

July 12th, 2021
Many thanks to Fraccaroli Gianmarco (@Fraccaman) for helping us improve the reliability of Forcerelay (#697).
This release includes two major features to Forcerelay: (1) support for reloading the chains from the configuration file at runtime, and (2) a filtering mechanism to restrict Forcerelay activity based on predefined parameters (e.g., packet relaying on certain ports and channels exclusively, and ignoring activity for clients that have non-standard trust threshold).
In addition to these two, we have also added a health checkup mechanism, plus new
config validate and query channel ends CLIs.
When upgrading from Forcerelay v0.5.0 to v0.6.0, the most important point to watch out for is the configuration file. The Forcerelay config.toml configuration file has went through a few revisions, with the changes described below.
Please have a look around the config.toml directly.
This feature will restrict the channels on which Forcerelay relays packets. There are two new options in the configuration file:
- A global
filterparameter to enable or disable filtering globally. - A per-chain
.filtersoption that expects apolicy(eitherallowordeny) plus a list of channel and port identifiers. If policy isallow, then packet relaying will be restricted to this list for the corresponding chain. If the policy isdeny, then any packets from this list will be ignored.
The global filter option additionally enables filtering of all activities
based on client state trust threshold. If enabled, Forcerelay will ignore all
activity for clients that have a trust threshold different than 1/3.
This will enable the parametrization of the frequency
at which Forcerelay will clear pending packets. This is a global option, called
clear_packets_interval, which applies to all chains in the configuration.
The full list of changes is described below.

This release brings a few features, and several improvements and bug fixes to the Forcerelay relayer, notably the capability for Forcerelay to complete IBC connection handshakes when it detects that one has been initialized, as well as the ability to detect chain impersonation attacks and to dynamically estimate the gas needed to submit a transaction.
Moreover, the overall reliability and availability of the relayer has also been improved
substantially by switching over to tx_broadcast_sync for submitting transactions.

- This release of Forcerelay features an internal telemetry service which can export metrics about the relayer to Prometheus.
- A new relaying strategy is now available, which enables Forcerelay to complete channel handshakes in an event-based fashion.
- Forcerelay now checks if another relayer may have already processed a packet event, and will not attempt to process it itself, which improves performance.
- The startup time of the relayer has been substantially improved.
- The
start-multicommand has been promoted tostart, which means that the worker-based relayer is not experimental anymore. - A regression where Forcerelay would not recover after a node went down and up again was fixed.

This release focuses on upgrading the relayer and ibc modules to the latest interfaces from the ecosystem:
tendermint-rs v0.17, which brings the protobuf changes from tendermint v0.34.0, plus alignment with
the latest cosmos proto versions from v0.40.0-rc5 (sometimes called 'stargate-5').
December 2, 2020
This release focuses on implementing relayer and relayer-cli functionality towards a full v0 implementation. We now have the full-stack implementation for supporting client creation & updates, as well as connection- and channel handshakes. We also consolidated our TLA+ specs into an "IBC Core TLA+ specification," and added ICS 020 spec.
Special thanks to external contributors for this release: @CharlyCst (#102, #419).

October 19, 2020
This release focuses on alignment with the Cosmos ecosystem: adaptations to Tendermint-rs 0.16 and subsequently to 0.17 (0.17.0-rc1), and numerous protobuf updates following latest stargate releases.
Additional highlights:
- Adding DomainTypes and (de)serialization capability to ICS02 and ICS03 messages and structures.
- Improvements of the IBC message processor framework (handlers, contexts and mocks).
- Added initial implementations for the ICS26 (routing module) and ICS18 (basic relayer algorithms module) for use in testing.
- Also added support for packet handling in the relayer algorithm specifications.

July 1st, 2020
This is the initial prototype release of an IBC relayer and TLA+ specifications. There are no compatibility guarantees until v0.1.0.
Includes:
- Configuration file definition and validation
- Client state, consensus state, connection, channel queries.
- Note: deserialization is unimplemented as it has dependency on migration to protobuf for ABCI queries
- Per chain light clients threads are created and headers are periodically retrieved and verified.
- Per chain IBC event monitor threads are spawned and main event handler that receives them.
- Note: the event handler just displays the events.
- IBC Modules partial implementation for datastructures, messages and queries.
- Some English and TLA+ specifications for Connection & Channel Handshake as well as naive relayer algorithm.
