Alessandro Alinone just announced a major update to Lightstreamer is expected in September, packed with a number of new features and additions.

Lightstreamer 3.5 will include the following components:

• Lightstreamer Server v. 3.5
• SDK for Java Adapters v. 3.5
• SDK for .NET Adapters v. 1.5
• SDK for Adapter Remoting Infrastructure v. 1.2
• SDK for Web Clients v. 4.3
• SDK for Flash Clients (JS Bridge) v. 1.1
• SDK for Flex Clients (Native AS) v. 1.1
• SDK for Java SE Clients v. 2.3
• SDK for Java ME Clients v. 2.1
• SDK for .NET Clients v. 1.2

Some of the new features and improvements include:

• Support for multiple Data Adapters used as part of the same session. A Metadata/Data Adapter Pair will be generalized to an “Adapter Set”, made up of a single Metadata Adapter and one or multiple Data Adapters. It will be possible to specify the Data Adapter to use for each Table subscription.
• It is now possible to include the internal Monitor Adapter in any Adapter set, to create custom monitor consoles.
• Optimization of high-frequency long-polling mode.
• New listeners in the Client libraries to handle item updates in a more consistent way across different SDKs.
• The engine migration algorithm in the Web Client is faster and more reliable.
• Optimized throttling heuristics for mobile devices.
• New MultiMetapush tables in the Web Client.
• Several new demos and examples.

Lightstreamer Server v.3.5 will maintain full backward compatibility with previous Clients and previous Adapters. Additional information is available at the Lightstreamer blog.
