Lightstreamer Web Client 8.1.0-beta

We have started the beta testing of the new Lightstreamer Web Client library, v. 8.1.0.

The main difference with the previous version is in the connection setup mechanism, also known as stream-sense. With version 8.1.0, instead of creating a session over HTTP and then switching to WebSocket, a session is created directly over WebSocket, while preserving the ability to fall back to HTTP. This means that in most cases, clients are able to set up the streaming channel with one connection only instead of two, reducing the session initiation time and overhead.

The new beta library is available on npm and you can test it in non-production environments.

Please get back to us for any feedback and questions.

Lightstreamer Server 7.1.2

We are happy to announce that Lightstreamer Server v. 7.1.2 is now publicly available.

You can download it, as usual, from

This new distribution does not contain the Lightstreamer SDKs anymore. With time passing, every SDK has found its own home within standard repositories, depending on the platform. So, it makes no more sense to bundle them with the Server distribution. For example, the JavaScripts libs are available on npm, the Java libs on Maven, etc. You can find all the links on the same download page.

Furthermore, Lightstreamer Server v. 7.1.2 contains some minor fixes and improvements (check out the changelog).
