[codxt]

Summary

Please add compatibility and first-class support for Telegram Bot API 10.2, released on July 14, 2026.

Official changelog: https://core.telegram.org/bots/api-changelog#july-14-2026

Relevant additions

Rich Messages

• Support InputRichMessage.media.
• Support InputMediaVoiceNote.
• Support the new outgoing rich block types, including lists, tables, details, collages, slideshows, media blocks, and thinking blocks.
• Support InputRichMessage.blocks for block-based outgoing rich messages.

Ephemeral Messages

• Parse BotCommand.is_ephemeral, Message.receiver_user, and Message.ephemeral_message_id.
• Support receiver_user_id and callback_query_id when sending messages and media.
• Support replies through ReplyParameters.ephemeral_message_id.
• Expose the new edit methods:
  • editEphemeralMessageText
  • editEphemeralMessageMedia
  • editEphemeralMessageCaption
  • editEphemeralMessageReplyMarkup
• Expose deleteEphemeralMessage.

Communities

• Parse the new Community, CommunityChatAdded, and CommunityChatRemoved objects.
• Handle Message.community_chat_added, Message.community_chat_removed, and ChatFullInfo.community without dropping or rejecting updates.

General compatibility

• Parse Update.subscription / BotSubscriptionUpdated.
• Upgrade or patch the Telegram client dependency as required for Bot API 10.2.
• Ensure unknown/new fields do not cause inbound updates to be discarded.
• Add adapter tests for representative 10.2 payloads and outbound method parameters.
• Document which 10.2 capabilities are exposed directly through Hermes and which remain pass-through only.

Motivation

Hermes uses Telegram as a primary agent interface. Bot API 10.2 adds user-specific ephemeral interactions and richer structured agent responses, both of which are particularly relevant to AI-agent workflows in shared chats.

A staged implementation is reasonable: payload compatibility and non-dropping parsing first, followed by first-class Hermes abstractions for ephemeral and rich-message capabilities.
