Hi Folks,

I've just updated Cuis to 2.1 at 
http://www.jvuletich.org/Cuis/Index.html . From the release notes:

Cuis Release notes
Only the most relevant Cuis specific changes are detailed here. To see 
all of them, browse the numbered changes themselves, that are part of 
this release. Cuis official site is

New in Cuis 2.1
- Support for the Unary numeral system, as suggested by Dan Ingalls at 
http://lists.squeakfoundation.org/pipermail/squeak-dev/2000-March/013368.html
- A new code differ that shows differences in words and not lines, by 
Leandro Caniglia
- Closure measurements (based on work by Eliot Miranda) are shown in the 
annotation pane for any method
- Removal of 43 isXXX methods, replaced by the general #is: method
- Misc. fixes and enhancements from Squeak and/or Pharo

New in Cuis 2.0
- Cuis is now closure-enabled. The closure examples xxxx work, and Cuis 
is ready to run on the Cog VM (when available). Cuis 2.0 requires a 
closures-enabled VM

I recommend everybody to see the new class comment in Number, and try 
the new number format! The alternative code differ by Leando, based on 
words and not lines is worth trying too. Finally, the Closure 
measurements for every method are instructive and useful. Warning: I 
fixed 2 bugs in Eliot's code, as I said in 
http://lists.squeakfoundation.org/pipermail/squeak-dev/2010-February/144120.html 
.

Comments welcome.
Cheers,
Juan Vuletich
