GNUstep Objective-C Runtime 1.8 =============================== This is a point release to the ninth official release of the GNUstep Objective-C runtime (a.k.a. libobjc2). This runtime was designed to support the features of modern dialects of Objective-C for use with GNUstep and other Objective-C programs. Highlights of this release include: - Added API for tracing, allowing interposition on all message sends matching a given selector. You may obtain the code for this release from subversion at the following subversion branch: svn://svn.gna.org/svn/gnustep/libs/libobjc2/releases/1.8 Alternatively, a tarball is available from: http://download.gna.org/gnustep/libobjc2-1.8.txz http://download.gna.org/gnustep/libobjc2-1.8.tar.bz2 http://download.gna.org/gnustep/libobjc2-1.8.tgz 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 backwards compatible with the FSF's GCC 4.2.1 Objective-C ABI and also implements a new ABI that is supported by Clang and Étoilé's LanguageKit and is required for some of the newer features. If you come across any problems, please report them to the GNUstep Developer mailing list .
