 - Add `UDP` and `S3` examples for `EventSource` and `EventSink` implementations to `hydra-node:examples`.
 
+- Switch `hydra-chain-observer` to use `HeadObservation` when reporting observations to `hydra-explorer`.
+  - Most observation types got changed quite a lot to match the previously used `OnChainTx`.
+  - This introduces `ToJSON` and `FromJSON` instances on all observation types.
+  - `CollectComObservation` and `ContestObservation` are made compatible with their `OnChainTx` counterparts.
+
 ## [0.21.0] - 2025-04-28
 
 - New metric for counting the number of active peers: `hydra_head_peers_connected`
