- error codes now accessed as ERR::NO_MEM, INFO::OK etc. - no more X-macros => the above are now recognized by visual assist - error codes are defined by the module originating them (lib_errors has some generic ones) => no full rebuild when adding some - error descriptions are now in C++ files => can be changed without full rebuild added AT_STARTUP in lib.h. This was SVN commit r4374.
