With Cognigy.AI 2026.4.0, the Step Explorer and Message Explorer in Insights are deprecated. The full removal of both Explorers, including removal from OData records, is planned for Cognigy.AI 2026.17.0.
In Cognigy.AI 2026.4.0, the OAuth2 authentication method for the Send SMTP Email Node was deprecated. The removal of this authentication method is scheduled for the release of Cognigy.AI 2026.16.0. To avoid disruptions in AI Agents using OAuth2 in this Node, migrate to the OAuth2 Client Credentials authentication method before the removal date.
