Key features

A complete list of the latest updates to Diffusion can be found in the Release Notes available at http://download.pushtechnology.com.

Paged topic support in the Java™ and .NET Unified API

You can use the TopicControl feature to create paged record topics and paged string topics and to define rule-based comparators to use for ordering the lines in the paged topic.

You can use the TopicUpdateControl feature to update paged record topics and paged string topics.

UpdateSource capabilities in the Unified API

The UpdateSource capabilities replace the TopicSource capabilities. UpdateSource includes the ability to build more complex updates, support for more topic types, and better handling of unexpected closes.

For more information, see the API documentation.

Remove topics after the control client closes using the Unified API

The TopicControl feature now enables you to specify whether to remove sections of the topic tree after a control client session closes.

For more information, see Removing topics with sessions.

.NET and C Unified API production support

The .NET and C Unified API are now supported for production use. Both APIs contain functionality to implement a control client.

For more information, see .NET and C.

Proxy support

Clients that use the Java Unified API can now connect to the Diffusion server through a proxy. The Unified API enables you to connect through the proxy unauthenticated, with basic authentication, or through any other authentication process by implementing your own challenge handlers.

For more information, see Connecting through an HTTP proxy.

WebSocket support in the iOS^® Classic API

Clients implemented using the iOS Classic API can now connect to the Diffusion server through the WebSocket protocol.

Streams replace listeners for receiving content through the Unified API

The Listeners in the Topics and Messaging features are now deprecated. Listeners have been replaced by streams. Topics.TopicStream receives topic events, such as topic updates for a topic or topics. Messaging.MessageStream receives messages sent through a topic or topics.

Streams provide advantages over listeners as a stream has a logical end. A stream can be closed or discarded, at which time the stream has the opportunity to do any required cleanup or take any required actions.

Flow control (Java Unified API)

The Java client library can now control the flow of requests from a client to decrease the likelihood of the client's outbound queue or the client queue on the server overflowing and causing the client to be disconnected.

This process happens automatically when the client detects conditions that might cause a queue overflow and increases the reliability of the Java client.
