 Name:		polynomials-bernstein
-Version: 	1.1.1
+Version: 	1.1.2
 Synopsis:	A solver for systems of polynomial equations in bernstein form
 Description: 	This library defines an optimized type for representing polynomials
 		in Bernstein form, as well as instances of numeric classes and other
 		manipulation functions, and a solver of systems of polynomial
 		equations in this form.
