Full Support for Bot API 10.1

What kind of feature are you missing? Where do you notice a shortcoming of PTB?

API 10.1

Telegram released Bot API 10.1 on June 11, 2026:

https://core.telegram.org/bots/api-changelog#june-11-2026

This release introduces Rich Messages and a few additional Bot API changes that are not yet exposed by PTB as far as I can tell. In particular, libraries and downstream integrations currently cannot use the new rich message methods and types through PTB's typed API.

• Added the class RichBlock.
• Added the class RichMessage.
• Added the field rich_message to the class Message.
• Added the class InputRichMessage, describing a rich message to send.
• Added the class InputRichMessageContent and allowed it to be used as InputMessageContent in results of inline, guest, and Web App queries.
• Added the method sendRichMessage, allowing bots to send rich messages.
• Added the method sendRichMessageDraft, allowing bots to stream partial rich messages.
• Added the parameter rich_message to the method editMessageText, allowing bots to edit rich messages.

Join Request Queries

• Added the field supports_join_request_queries to the class User.
• Added the field guard_bot to the class ChatFullInfo.
• Added the field query_id to the class ChatJoinRequest.

Polls

Describe alternatives you've considered

For now, users can call the new methods through the raw Bot API request layer and build the InputRichMessage payloads as plain dictionaries. That works around the missing typed support, but it bypasses PTB's typed interface and convenience methods.

Additional context

Rich Messages are especially relevant for bots that render structured or AI-generated output: headings, lists, tables, code blocks, collapsible sections, LaTeX/math expressions, media blocks, and streamed draft replies.
