13.6.1 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.
• The Prolog flag redefine_warnings can take new values, and is no longer ignored in runtime systems. See Prolog Flags.
• 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 and The Foreign Resource Linker.
• sicstus The new (POSIX) option -- is a synonym for the old -a.
