14.6.1 New Features

• The new Prolog flag legacy_char_classification makes it possible to use full Unicode, e.g. Chinese characters, in unquoted atoms and variable names. See Prolog Flags in the SICStus Prolog Manual.
• The Prolog flag redefine_warnings can take new values, and is no longer ignored in runtime systems. See Prolog Flags in the SICStus Prolog Manual.
• SP_load_sicstus_run_time(), and related functionality for loading multiple SICStus runtimes into a process, is now available.
• Jasper Java interface (library(jasper)) is now available. Jasper is mainly for legacy code; PrologBeans is still the preferred method of calling Prolog from Java.
• library(sockets) now supports UNIX domain (AF_UNIX) sockets on UNIX-like platforms. The new predicate socket_server_open/3 allows some options when opening a server socket.
• SP_set_argv(), a new C API function for setting the values returned by the argv Prolog flag. Similar to the argv argument to SP_initialize(), but can report failure and can use locale information.
• spld and splfr: new command line options. The new (POSIX) option -- is treated the same as the older -LD. New option --conf VAR=VAL to override variable VAR in the configuration file. Option processing has been rewritten to be more robust and consistent. See The Application Builder in the SICStus Prolog Manual and The Foreign Resource Linker in the SICStus Prolog Manual.
• sicstus The new (POSIX) option -- is a synonym for the old -a.
