(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 for good. + - New dynallocate(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().
