+This release brings major improvements to error handling in `ibc-rs`, giving
+hosting environments better control over errors and easier debugging for the
+developers. A key enhancement is the clearer distinction between host-sourced
+errors and those propagated by `ibc-rs`, effectively separating host-level
+errors from protocol-level ones. Therefore, a noticeable update is the renaming
+of the previous `ContextError` to `HandlerError`, which now exclusively manages
+errors from IBC handlers. In parallel, a new `HostError` has been introduced to
+handle errors originating from hosts, particularly those from validation and
+execution contexts. Additionally, error definitions within `ibc-rs` have been
+unified, reducing the granularity of error variants. For more details, please
+refer to [ADR-011](./docs/architecture/adr-11-refactor-errors.md).
+
+In addition, it introduces various fixes and enhancements. Notably, helper
+traits with default implementations have been added to simplify the conversion
+between host time types and `Timestamp`. Consequently, the `ibc-primitives`
+crate has been fully decoupled from the `tendermint` dependency.

+It’s also worth noting that the `cosmwasm` workspace has been relocated to its

+
+### BREAKING CHANGES
+
+- [ibc] Standardize error variants across the codebase to make them less
+  specific and more consistent.
+  ([\#270](https://github.com/cosmos/ibc-rs/issues/270))
+- [ibc-core-handler] Return `DecodingError` for `MsgEnvelope` when trying to
+  decode from `Any` ([\#950](https://github.com/cosmos/ibc-rs/issues/950))
+- [cosmwasm] Migrate the `cosmwasm` workspace into its own separate repository
+  located at [cosmwasm-ibc](https://github.com/informalsystems/cosmwasm-ibc).
+  ([\#1311](https://github.com/cosmos/ibc-rs/issues/1311))
+- [ibc] Consolidate decoding-related errors into new `DecodingError` type
+  ([\1319](https://github.com/cosmos/ibc-rs/issues/1319))
+- [ibc-core] Define a new `HostError` type in ICS-24 to draw distinction between
+  protocol errors and host errors. Additionally, rename `ContextError` to
+  `HandlerError` to better reflect its use case.
+  ([\1320](https://github.com/cosmos/ibc-rs/issues/1320))
+- [ibc-core-channel] Merge `PacketError` type into `ChannelError`
+  ([#1339](https://github.com/cosmos/ibc-rs/issues/1339))
+- [ibc] Clean up multi-purpose variants like the `Other` variant and reduce
+  unnecessary `String` allocations in `*Error` enums.
+  ([\#1346](https://github.com/cosmos/ibc-rs/issues/1346))
+- [ibc-core-client] Update ICS-02 `ConsensusState::timestamp()` to return
+  `Result<Timestamp, ClientError>`
+  ([\#1352](https://github.com/cosmos/ibc-rs/issues/1352))
+
+### BUG FIXES
+
+- [ibc-core] Remove faulty receipt check during `recv_packet_validate`
+  ([#1336](https://github.com/cosmos/ibc-rs/issues/1336)).
+
+### IMPROVEMENTS
+
+- [ibc-primitives] Define utility traits for converting between `Timestamp` and
+  host-specific time types.
+  ([#1323](https://github.com/cosmos/ibc-rs/pull/1323)).
+- [ibc-testkit] Remove redundant path constructions in the implementation of
+  `ValidationContext` for `MockIbcStore`
+  ([#1338](https://github.com/cosmos/ibc-rs/pull/1338)).
