What's New in JACOB 1.7

• Explicit COM Threading Model Support: See a detailed discussion of COM Apartments in JACOB
• New COM Object Lifetime model: See a detailed discussion of COM Object Lifetime in JACOB.
• Improved Event Handling: Thanks to code contributed by Niels Olof Bouvin and Henning Jae JACOB 1.7 can read the type information of a Connection Point interface by looking it up in the registry. This makes it possible to use events with IE as well as office products.
• Improved Dispatch: Error messages from Invoke failures are now printed out as well as allowing the passing in of arguments to a Get method.
• EnumVariant Implementation: Makes it easier to iterate over COM collections. Thanks to code contributed by Thomas Hallgren.
• SafeArray leaks: SafeArrays were not being properly freed prior to version 1.7, many other memory leaks were fixed as well.
• Visual Studio Project: For those who want to debug: vstudio/jacob. At the moment all the native code is replicated there from the jni directory...
