If + you have block files around, prepend 1024 bytes to convert them, or + do a "1 OFFSET !" to establish the old behaviour. +Gforth now does not translate newlines to LFs on reading. Instead, + READ-LINE now interprets LF, CR, and CRLF as newlines. Newlines on + output are in the OSs favourite format. +SEE now disassembles primitives (or hex-DUMPs the code if no + disassembler is available). +>HEAD (aka >NAME) now returns 0 (instead of the nt of ???) on failure. +Syntax of prim changed: stack effects are now surrounded by + parentheses, tabs are insignificant. + +Operating environment: + +Gforth now produces a backtrace when catching an exception. +On platforms supporting the Unix 98 SA_SIGINFO semantics, you get more + precise error reports for SIGSEGV and SIGFPE (e.g., "stack + underflow" instead of "Invalid memory address"). +Gforth now produces exit code 1 if there is an error (i.e., an + uncaught THROW) in batch processing. +You can use "gforthmi --application ..." to build an image that + processes the whole command-line when invoked directly (instead of + through gforth -i). + +Ports: + +AIX. +20% speedup on 604e under powerpc-unknown-linux-gnu, +19%-29% speedup on Celeron with gcc-2.95. + +New words: + +Missing ANS Forth words: EKEY EKEY?
