In this release, we've undertaken a comprehensive overhaul of the ibc-rs
repository, resulting in a strategic reorganization of the codebase. This
restructuring dissects the implementation of each IBC specification,
categorizing and situating them within relevant libraries. The primary objective
is to elevate ibc-rs
practicality and enhance user flexibility by providing a
more modular and composable experience.
Users now have the flexibility to choose from a spectrum of dependencies. They
can opt to utilize the entire suite of meta-crates, such as ibc
, ibc-core
,
ibc-clients
, or ibc-apps
. Alternatively, they can exercise fine-grained
control by selectively importing specific crates. This can involve bringing in
an entire implemented IBC sub-module, like the ibc-core-client
crate, or
importing only the associated data structures of a module, such as the
ibc-core-client-types
crate.
Furthermore, this release introduces optimizations centered around construction and validation of ICS-24 host identifiers, aiming to curtail some heap allocations, beneficial for resource-constrained hosts.
There are no consensus-breaking changes.

October 12, 2023
This release introduces vital bug fixes, including removal of an incorrect validation during a Tendermint client update and the addition of a missing state update during a successful client upgrade ensuring the inclusion of the host's height and timestamp in the store.
Additionally, it eliminates the safe-regex
dependency, and restructures IBC
query implementations under the previous grpc
feature flag and moves it to a
separate crate called as ibc-query
.
There are consensus-breaking changes.

event where the header
field was not properly encoded.

August 4, 2023
The goal with this release was to replace ClientState::{confirm_not_frozen, expired}()
with ClientState::status()
(#536). Updating basecoin-rs with the new changes exposed the shortcomings of having SendPacket*Context
be supertraits of TokenTransfer*Context
, which in turned exposed the shortcomings of having Router
be a supertrait of ValidationContext
. Hence, we decoupled everything!
There are consensus-breaking changes.
- [ibc-derive] Replace
ClientState::{confirm_not_frozen, expired}()
withClientState::status()
(#536) - Decouple
TokenTransfer{Validation,Execution}
fromSendPacket{Validation,Execution}

height creation, synchronized channel
event namings for consistency.

May 8, 2023
This release primarily consolidated the modules in the ibc-rs crate, removed many legacy items, and documented every item in the crate. This represents a big step towards v1.0. Very few items changed name; most were just moved to elsewhere in the module tree. Perhaps a good heuristic to fix the breaking changes is the remove the faulty use
statements, and have your editor re-import the item.
There were also a few minor validation checks missing, which we added. These were pretty much the last remaining known ones.

This release involves splitting the newly defined MsgUpdateClient
type in
v0.37.0 into distinct IBC message structs: MsgUpdateClient
and
MsgSubmitMisbehaviour

store_client_type
interface, and removed IbcEventType

event variant to define its own set of event types.

This is the initial prototype release of an IBC relayer and TLA+ specifications. There are no compatibility guarantees until v0.1.0.
Includes:

- Note: deserialization is unimplemented as it has dependency on migration to protobuf for ABCI queries
- IBC Modules partial implementation for datastructures, messages and queries.
- Some English and TLA+ specifications for Connection & Channel Handshake as well as naive relayer algorithm.
