 This file records noteworthy changes.
 
+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.
+
+1.7.11 (3 August 2020)
+* Fix elusive bugs in factor() and in expand().
+
+1.7.10 (28 June 2020)
+* Fix collect_common_factors() for hidden zero arguments.
+* Fix build on modern systems (C++20 and Python3).
+
+1.7.9 (11 April 2020)
+* Fix unarchiving of overloaded functions.
+* Fix MinGW64 build.
+
+1.7.8 (7 October 2019)
+* Fix pseries::evalf(), broken since 1.7.0.
+* Fix a corner-case bug in H_evalf().
+
+1.7.7 (22 September 2019)
+* Fix unarchiving empty containers.
+* Remove obsolete exhashmap implementation.
+* Fix issues with zeta computation.
+* Build with Python3.
