Sngine Messenger 2.0.1 is a maintenance and compatibility release for the Flutter messaging app. It fixes reported bugs, improves API integration and continues the work introduced in Messenger 2.0.0.

For customers running a Sngine-powered social platform, the Messenger app is one of the most important mobile experiences. Chat must feel fast, calls must be reliable and media should load without making the app feel heavy.

What changed in 2.0.1?

• Fixed reported bugs and customer issues.
• Updated API integration for better communication between app and server.
• Requires the related API update on the website/server side.

Important features from the Messenger 2.0 line

The larger Messenger 2.0.0 release added a caching system for chats, videos, images and stories. This improves conversation loading, reduces repeated media loading and creates a smoother browsing experience.

The release also added the ability to send music files directly from the phone, delete accounts, block users and receive Firebase call notifications for background voice and video calling.

Why caching matters in a chat app

Messaging apps are opened many times per day. Users expect conversations, images and videos to appear quickly, even when the network is not perfect. A better cache strategy helps reduce waiting and makes repeated views feel instant.

Flutter's official performance documentation recommends avoiding expensive UI work and unnecessary rebuilds. In real products, caching also helps because it reduces repeated network and media work in the user journey.

Update advice for customers

If a release note says the API must be updated, update both the mobile app files and the server-side API files. Using a new app with an old API can cause missing features, failed calls or inconsistent data.

Before applying the update to production, make a backup and test these flows:

• Login and account access.
• Sending text messages, images, videos, files and music.
• Voice and video call behavior in foreground and background.
• Push notification behavior.
• Blocking and account deletion flows.
