Button Revolution• Buttons can now be placed right inside any rich message – with multiple native styles and custom alignment.
• Out of the box, these buttons support callbacks, Mini Apps, Login URLs, copying text and more.
• Bots can now mark inline buttons as disabled.
Ephemeral Messages• Bots can now replace their messages with an ephemeral overlay, then edit it with rich content or newly uploaded media. This unlocks rich, personalized flows and responses running in a single message.
Rich Messages• Bots can now attach documents to rich messages and more easily embed media – including previously uploaded files.
• Rich Messages now support expandable quote blocks and compact tables.
AI Agents• Bots now support a native Stop button for streamed drafts and can optionally preserve partial responses.
