Hi folks,
I started work on version 2 and it's already usable, although not yet
as good as v1 in terms of compression. The goals of the rewrite are
to have cleaner and more maintainable code, a better AST structure
(now using objects instead of arrays), full location information in
all nodes, add support for generating source maps and keeping certain
comments in the compressed output.
More info at the project page:
