almost all functions and constants can be converted to Sage
univariate factorization algorithm was fixed
.evalf() method fixed, pi.evalf(106) calculates 1 000 000 digits of pi
@threaded decorator
more robust solvers, polynomials and simplification
better simplify, that makes a solver more robust
optional compiling of functions to machine code
msolve: solving of nonlinear equation systems using Newton's method
((x+y+z)**50).expand() is now 3 times faster
caching was removed from the Order class: 1.5x speedups in series tests
