• React to Instagram DMs: your connected account can now react to a delivered Instagram message with an emoji, or remove the reaction, via POST/DELETE /v1/conversations/:id/messages/:messageId/reactions. The message object now returns a reaction field showing the account's own reaction. Facebook DM reactions aren't available yet.
• Bluesky posts with 5–10 images no longer drop photos: Bluesky posts with more than 4 images were silently truncated to 4 even though the post reported success. Galleries of 5 to 10 images now publish in full; posts with more than 10 images are rejected up front instead of being quietly cut down.
• Facebook messaging setup is now fully documented: the Conversations setup guide and a new Facebook Direct Messages reference cover connecting a Facebook Page for messaging, required scopes, comment-to-DM private replies, and the 24-hour messaging window, alongside the existing Instagram documentation.
