------------
+ Runtime and core library:
- The main focus of this release was getting the UI framework in a state
where the graphical listener is usable. This goal has largely been
achieved. Many performance problems were fixed, and the listener now
supports styled text output, presentations, and an
automatically-updated data stack display.
- The number of generations used for garbage collection can now be set
with the +G command line switch. You must specify at least 2
@ -10,11 +14,7 @@ Factor 0.76:
- Only 2 generations are used by default now, since there seems to be no
performance benefit to having 3 after running some brief benchmarks.
- New words:
math bitroll ( n s w -- n )
unparser hex-string ( str -- str )
sequences fourth ( seq -- elt )
- Many improvements to the matrices library.
- String input streams.
