LIGHTSTREAMER CHANGELOG
SDK for Java SE Clients (Unified API Version)
3.1.3 build 1278
Compatible with Lightstreamer Server since 6.0.1.
Compatible with code developed with the previous version.
Released on 14 Nov 2016

Fixed a bug which could have caused onSubscriptionError and onCommandSecondLevelSubscriptionError to report wrong error codes, that is, codes different from the documented ones.

Fix the documentation of onClearSnapshot, which is only predisposed.

3.1.2 build 1274
Compatible with Lightstreamer Server since 6.0.1.
Compatible with code developed with the previous version.
Released on 30 Aug 2016

Added meta-information on method argument names for interface classes, so that developer GUIs can take advantage of them.

3.1.1 build 1270
Compatible with Lightstreamer Server since 6.0.1.
Compatible with code developed with the previous version.
Released on 22 Jul 2016

Clarified the documentation in regard to a few API methods that still have a partial implementation or are just predisposed and not implemented yet.

3.1.0 build 1269
Compatible with Lightstreamer Server since 6.0.1
May not be compatible with code developed with the previous version; see compatibility notes below.
Released on 10 May 2016

Changed the names of some properties in the ConnectionOptions bean. To resume:

This affects the getter and setter names and also the invocations of onPropertyChange on the ClientListener. COMPATIBILITY NOTE: Custom code using any of the mentioned properties has to be ported and any related binaries have to be recompiled.

Added logging messages (at ERROR level) for those cases in which runtime exceptions could be thrown while running some asynchronus code paths.

Fixed potential NullPointerException which could be thrown when setting or updating fields and/or items list if logging is enabled at DEBUG level.

Fixed an error in the log of the keepalive interval setting.

Fixed the documentation of onServerError and onStatusChange, to specify that onServerError is always preceded, not followed, by onStatusChange with DISCONNECTED.

Revised javadoc formatting style and fixed various typos in the javadocs.

Updated the versions of some external libraries which the SDK depends upon.

3.0 build 1265.1
Compatible with Lightstreamer Server since 6.0.1
May not be compatible with code developed with the previous version; see compatibility notes below.

Changed the type and behavior of the getConnectTimeout/setConnectTimeout. This setting is now represented as a String in order to accept the "auto" value. If "auto" is specified the value used internally will be chosen (and possibly changed overtime) by the library itself. Note that "auto" is also the new default value.

To check and or modify the current value, a new CurrentConnectTimeout property, with its getter/setter pair in ConnectionOptions, is exposed. COMPATIBILITY NOTE: if the setConnectTimeout method is called by the client code, the given parameter must be modified to be a String. If the getConnectTimeout method is called by the client code its receiving variable must be converted to a String; moreover it is likely that getConnectTimeout calls should be replaced by getCurrentConnectTimeout ones. See the docs for further details.

Added the new method disconnectFuture to the LigtstreamerClient class, with the purpose to provide a notification when all threads started by all LightstreamerClient instances living in the JVM have been terminated, because no more activities need to be managed and hence event dispatching is no longer necessary.
Such method is especially useful in those environments which require an appropriate resource management, like "full" Java EE application servers or even the simpler Servlet Containers. The method should be used in replacement of disconnect() in all those circumstances where it is indispensable to guarantee a complete shutdown of all user threads, in order to avoid potential memory leaks and waste resources.
See the docs for further details about the proper usage pattern for this method.

Prevented reconnection attempts upon wrong answers from the Server.

3.0 b2 build 1261
Compatible with Lightstreamer Server since 6.0.1.
May not be compatible with code developed with the previous version; see compatibility notes below.
Made available as a prerelease on 6 Oct 2015

Resorted to an external package for the log support. COMPATIBILITY NOTE: Custom code using the LoggerProvider interface should be revised, based on the new documentation; see setLoggerProvider.

Introduced the possibility to override the library-set HTTP headers through the ConnectionOptions.setHttpExtraHeaders method (previously it was the other way round).

Improved the handling of long polling.

Added missing documentation of setProxy in ConnectionOptions.

3.0 b1 build 1253
Compatible with Lightstreamer Server since 6.0.1.
Made available as a prerelease on 16 Jul 2015

Introduced as an improved alternative to the SDK for Java SE Clients. The interface offered is completely different, and it is very similar to the one currently exposed by the SDK for JavaScript Clients.
see "sdk_client_java_se_beta".
