This file records noteworthy changes.
++1.7.0 (TDB)
++* Make use of C++11 features:
++ - Use new language features 'auto', 'nullptr', 'constexpr', range-based for
++ loops, the contextual keyword 'override', static 'noexcept' operator, etc.
++ - Add initializer list ctors for container<>, lst and nested initializer
++ lists ctor for class matrix.
++ - Add many rvalue reference overloads for ctors from std containers. (Note
++ that whether they really speed up things depends on whether evaluation
++ leaves the container unchanged or not.)
++ - Rvalue reference overloads for ctors from std containers made it possible
++ to remove the manual 'discardable' hack and std::auto_ptr<T> for good.
++ - New dynallocate<T>(args...) helper functions obsolete manual allocation
++ on the heap and setting the dynallocated status flag.
++ - Got rid of C++98ish algorithm features (bind2nd, etc.) and replaced them
++ with lambdas.
++* Make add::eval(), mul::eval() more careful so they return an evaluated,
++ canonical expression without compromise.
++* Remove 'level' argument of all .eval() methods. This has become possible by
++ ensuring that add::eval() and mul::eval() evaluate their own structure
++ without compromise (this was not guaranteed before). If all ex are evaluated,
++ any object which is an aggregate of such ex will only ever have to
++ evaluate itself, obsoleting the need for recursing.
++* Remove 'level' arguments of all .evalf() and .normal() methods. They were
++ modeled after the .eval() methods.
++* Make relational::rhs() and lhs() nonvirtual.
++* Add support for power::info(info_flags::real).
++* Remove broken info_flags::algebraic.
++* Remove unmaintained support for Cint.
++* Remove unfinished andcode for hash table-based expairseq.
++* Remove deprecated ex::to_rational(lst) and ex::to_polynomial(lst).
++* ginac-excompiler installs in $LIBEXECDIR now, not in $BINDIR.
++* Many minor performance enhancements.
++
+1.6.7 (29 February 2016)
+* Fix elusive bug in sqrfree(), normal(), numer(), and denom().
+
+1.6.6 (20 December 2015)
+* Fix elusive bug in add::eval().
+* Several minor performance enhancements.
+
1.6.5 (27 July 2015)
* Fix pow(+(...),2).expand() where the sum contained roots of expressions.
* Speed-up pow(+(...),n).expand() where n > 3.
