The entries below contain brief descriptions of the changes in a release, in no particular order. Some of the entries reflect significant new additions, while others represent minor corrections. Although this list is not a comprehensive report of every change we made in a release, it does provide details on the changes we feel Ice users might need to be aware of.

We recommend that you use the release notes as a guide for migrating your applications to this release, and the manual for complete details on a particular aspect of Ice.

Changes in Ice 3.7.0

These are the changes since Ice 3.6.1.

General Changes

  • IceGrid and IceStorm now use LMDB for their persistent storage instead of Freeze/BerkeleyDB.

  • Added command line tools, icegriddb and icestormdb, to import/export the IceGrid and IceStorm databases.

  • Added support for two additional IceGrid variables: server.data and service.data. These variables point to server and service specific data directories created by IceGrid on the node. These data directories are automatically removed by IceGrid if you remove the server from the deployment.

    For consistency, the node.datadir variable has been deprecated, use the node.data variable instead.

  • Added the new metadata tag delegate for local interfaces with one operation. Interfaces with this metadata will be generated as a std::function in C++11, delegate in C#, FunctionalInterface in Java, function callback in JavaScript, block in Objective-C, function/lambda in Python. Other language mappings keep their default behavior.

  • ObjectFactory has been deprecated in favor of the new local interface ValueFactory. Communicator operations addObjectFactoryand findObjectFactory have been deprecated in favor of addValueFactory and findValueFactory.

  • Renamed local interface metadata async to async-oneway.

  • Replaced ConnectionCallback by delegates CloseCallback and HeartbeatCallback. Also replaced setCallback by setCloseCallback and setHeartbeatCallback on the Connection interface.
