 ## Unreleased
 
+## [0.28.0] - 2023-09-21
+
 * Added `DelegatedIdentity`, an `Identity` implementation for consuming delegations such as those from Internet Identity.
 * Replica protocol type definitions have been moved to an `ic-transport-types` crate. `ic-agent` still reexports the ones for its API.
 * The `Unknown` lookup of a request_status path in a certificate results in an `AgentError` (the IC returns `Absent` for non-existing paths).
