+Additionally, operators can now override the CometBFT compatibility mode to be used
 for a chain by using the new `compat_mode` per-chain setting. The main use case for this
 is to override the automatically detected compatibility mode in case Hermes gets it wrong
 or encounters a non-standard version number and falls back on the wrong CometBFT version.

+- Allow relaying ICS-04 packets with non-UTF-8 payloads ([\#3770](https://github.com/informalsystems/hermes/issues/3770))
+  Hermes does not assume anymore that an ICS-04 packet data is valid UTF-8,
+  by using the `packet_data_hex` attribute when assembling a packet from events, instead of the deprecated `packet_data` attribute.
+  Relying on the `packet_data` attribute enforces a UTF-8 encoded payload (eg. JSON), disallowing eg. Protobuf-encoded payloads.
+  The `packet_data` attribute [has been deprecated][0] in favor of `packet_data_hex` since IBC-Go v1.0.0.
