GNUstep Objective-C Runtime 1.0 =============================== This is the first official release of the GNUstep Objective-C runtime (a.k.a. libobjc2). This runtime was designed to support the features of Objective-C 2 for use with GNUstep and other Objective-C programs. The runtime library is responsible for implementing the core features of the object model, as well as exposing introspection features to the user. The GNUstep runtime implements Apple's Objective-C Runtime APIs, and a small number of GCC APIs for legacy compatibility. This library is based on the Étoilé Objective-C Runtime, an earlier research prototype, and includes support for non-fragile instance variables, type-dependent dispatch, and object planes. It is fully compatible with the FSF's GCC Objective-C ABI and also implements a new ABI that is supported by Clang and is required for some of the newer features.
