The main feature of Signals2 over Signals is thread-safety.  Another reason to 
use it is that the original Signals library will probably be deprecated and

The original Signals library has more real-world testing, since 1.39 is the 
first boost release including Signals2.  It probably also has better support 
for old compilers.

There is a porting section in the documentation that describes the 
differences:
