Telegram Bot API 10.2 Adds Rich Messages, Ephemeral Edits, and Community Events
Telegram released Bot API 10.2 on July 14, 2026, introducing several changes affecting production bots across four key areas. Rich Messages now support typed content blocks, embedded media, and new InputRichBlock builders, while ephemeral messages gain a full send, edit, and delete lifecycle. Communities introduce new topology events and expanded metadata via ChatFullInfo, and Mini Apps receive stricter cross-origin method protection. Developers are advised to roll out the upgrade in stages — first updating data models and event dispatchers, then enabling new outbound features behind feature flags. Pinning a compatible library version and running regression tests before production deployment is strongly recommended to avoid serialization errors or dropped events.
