First off (oh no, another bad pun), you must think that I can't count. Yes, I know 9 doesn't come after 4 but I thought it was time bump the version number a bit. This is basically the beta-release for 0.10 which implies that most functionality is in the backend and there's a usable console front end. After v0.10, work will concentrate on a GUI and not the console. However, the console will be there forever and ever.
In this release, just about all functions of the BS2 used in the FIRST Robotics Competition are implemented (basically, I can't think of any more that I can think of using, if you can, please tell me). This includes for-loops, lookup, and lookdown.
There are numerous bug-fixes in this release. Basically, all the code I have (from several different teams doing different things) runs on it and does not cause any errors (that said, I don't know if the output is correct). If you're code doens't run on it, please send it to me and I'll make things work.
Also in this release, there is a command-interpreter for the console. The command interpreter currently accepts several commands:
open - open a set of files for interpretting; follow the command by the list of files
run - run the open files
continue - continue from a breakpoint
break - set a breakpoint; follow the command by the file number and line number
print - print the value of a symbol (variable, constant, etc.)
quit - quit the interpreter
There also is a README and Changelog available on the web site.
