+1.8.6 (8 February 2023)
+* Fix wrong numeric info on transcendental functions.
+* Fix crash of evaluation of binomial(n, k) with negative integer n, k.
+
+1.8.5 (1 January 2023)
+* Speed up multivariate polynomial factorization; fix it in some rare
+ corner cases where it didn't previously terminate.
+
+1.8.4 (19 September 2022)
+* Add support for sqrfree_parfrac().
+* Add info methods for transcendental functions.
+
+1.8.3 (23 March 2022)
+* series_to_poly() can be used from ginsh.
+* Fix power::to_polynomial() for posint exponents.
+* Fix power::subs() in some special cases.
+
+1.8.2 (1 January 2022)
+* Fix elusive bug in comparing relational objects.
+* Ensure modular_form_kernel::series() includes an Order term.
+
+1.8.1 (9 August 2021)
+* Add method relational::canonical() and improve conversion of relational to
+ Boolean (it now works on many simple symbolic cases).
+* Improve normalization of negative exponents.
+* Fix indexing multiply referenced objects with ex::operator[].
+* Make functions evalf() their arguments before doing own evalf().
+* Fix bugs in H_evalf() and in evaluation of iterated integrals.
+* Several portability improvements and compiler warning fixes.
+
+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.

+* Fix unarchiving empty containers.
+* Remove obsolete exhashmap implementation.
+* Fix issues with zeta computation.
+* Build with Python3.
+
+1.7.6 (22 April 2019)
+* Fix a bug in mul::series() about asymptotic order term.
+* Fix cl_N code generation for small negative integers.

+ signs for small imaginary parts.
+* Fix CMake build with Python3.
+
+1.7.5 (17 February 2019)
+* Add Markowitz-ordered Gaussian eliminatin.
+* Avoid un-normal zeros in matrix::solve().
+* Accept exprseq arguments in lsolve(eqns, vars).
+* Add overload of matrix::rank(solve_algo).
+* Fix case in G_do_hoelder with real x values which are not cl_R.
+* Fix an elusive bug in expairseq/add ctor, introduced in 1.7.0.
+
+1.7.4 (19 February 2018)
+* Fix ABI compatibility with 1.7.[0-2] (broken unintentionally in 1.7.3).
+
+1.7.3 (1 February 2018)
+* Speed up some corner cases of polynomial factorization.
+* Speed up some corner cases of gcd computation.
+* Speed up factorization of pre-factored polynomials.
+* Make matrix::solve() work with hidden (non-normal) zeros.
+* Fix bug in evaluation of real and imaginary parts of powers.
+* Fix some LaTeX output, add new function symbol::get_TeX_name().
+
