-* improve power::info(): power with a real base and even exponent
+* Improved power::info(): power with a real base and even exponent
   reports that it's non-negative.
 * Fixed spurious match failure due to expairseq::match() bug:

   FAIL
-* fixed power::is_polynomial() and mul::is_polynomial() computation.

 * factor_univariate correctly handles polynomials over rationals (no
   segfaults any more).
-* fixed an infinite loop in factor_multivariate due to incorrect handling
+* Fixed an infinite loop in factor_multivariate due to incorrect handling

 * Fixed several build issues:
   - libreadline and dlopen() misdetection.
   - multiple definition of symbol on MinGW.
   - auto* tools and texinfo being unhappy in various ways.
 * GiNaC can be built with CMake now.

 * Fixed the parser to read GiNaC::lst again.
 * Fixed a compile warning (relevant to openSUSE build).
