+1.8.0 (14 October 2020)
+* New routines for the numerical evaluation of iterated integrals like
+ elliptic multiple polylogarithms or iterated integrals of modular forms.
+* Stronger normalization methods for expressions with powers. Where this
+ is safe, GiNaC now tries replacing various kinds of powers in order to
+ find and cancel common subexpressions.
+* Improved CMake build.
