FriCAS is an advanced computer algebra system. Its capabilities range from calculus (integration and differentiation) to abstract algebra. It can plot functions and has integrated help system.
FriCAS 1.1.5 builds on Linux and many Unix like systems (for example Mac OSX and Solaris 10). FriCAS is build on top of Common Lisp; several Lisps can compile and run FriCAS  currently supported are GCL, SBCL, Clisp, ECL, Closure CL.

Notable changes (compared to version 1.1.4):
 Added numeric version of lambertW.
 New function 'rootFactor' which tries to write roots of products as products of roots.
 'try', 'catch' and 'finally' are now Spad keywords.
 Experimental support for using gmp with Closure CL (64bit Intel/Amd only).
 New categoris CoercibleFrom and ConvertibleFrom. New domain for ordinals up to epsilon0. New domain for matrices of machine integers. New package for solving linear equations written as expressions (faster then general expression solver).
 Functions exported by Product() are now called 'construct', 'first' and 'second' (instead of 'makeprod', 'selectfirst' and 'selectsecond' respectively).
 Some functions are now much faster, in particular bivariate factorization over small finite fields.
 When using sbcl FriCAS now tries to preload statistical profiler.
Bug fixes, in particular:
 Fixed handling of ControlC in FriCAS compiled by recent sbcl.
 Fixed HyperDoc crash due to bad handling of '#'.
 Fixed power series expanders for elliptic integrals.
 Fixed 'possible wild ramifcation' problem with algebraic integrals.
 'has' in interpreter now correctly handles '%'.
 Spad compiler can now handle single '=>' at top level of a function.
 Fixed few problems with conditional types in Spad compiler.
