September 23, 2026 — Favorite chats sync event

Features

Favorite chats sync event (#1544) The client now dispatches FavoritesUpdate when the favorites mutation arrives through app state sync. Before this change, you could write the favorite chats list with send_app_state_action and schemas::FAVORITES, but the phone’s list was decoded and dropped. The event carries action.favorites (the full list in the phone’s order, each entry’s id a chat JID string), the mutation timestamp, and from_full_sync.

use wacore::types::events::Event;

.on_event(|event, _client| async move {
    if let Event::FavoritesUpdate(update) = &*event {
        let chats: Vec<&str> = update
            .action
            .favorites
            .iter()
            .filter_map(|f| f.id.as_deref())
            .collect();
        println!("Favorite chats: {chats:?}");
    }
})

Each event replaces the previous list rather than describing a delta. An empty list is the valid “no favorites” state and still fires the event.
