MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.


This version contains a number of small fixes. The Arg() methods in the String class are now less error-prone. Short-circuit logic in the QueryFilters was improved. The DefaultConsoleLogger and DefaultFileLogger classes were exposed for re-use elsewhere. .pro files were updated for compatibility with Qt 5.0.
