Release of version 1.0.47 (May 20th 2001)
* initial texmacs support.
* Jitse Niesen greatly improved the parts of the manual on
variables and on input/output.
* Bug fix in localrules (didn't work on more complex input,
because it didn't check the leading function type!)
* Bug fix : loading of files on Windows was broken. The Windows
client didn't handle Unix-style end-of-lines too well.
* Renamed TryRetract to Retract (Suggested by Jitse).
* Put NewLine and Space in the scripts as opposed to in the Yacas
kernel (Suggested by Jitse).
* Jitse added one-liner descriptions for functions in the
documentation.
* latex form in texmacs.
* Greatly improved CanProve, thanks to Vladimir.
* Initial version of Berlekamp factoring.
* changed all the scripts so they have the extension .ys.
* proteusdebugger: an initial version of a debugger for yacas.
* Change to configure script to support compiling under cygwin,
with plugin support.
* Bug fix to multiplying complex numbers with lists.
* Made Content and PrimitivePart respond more nicely to
polynomials with rational coefficients.
* Small improvement to the debugger: it now also steps to
non-expandable lines when you use the step buttons.
* numbers with a minus sign now parsed into negative numbers, as
opposed to a function -(number)
* configurable simplification of inequalities in the logic code.
* Split out the tests into many test scripts in directory tests/
Release of version 1.0.46 (April 10th 2001)
* Bug fix: N(Sin(a)) returning 0 (also a problem with Cos). The
problem was due to the system trying to do a SinMap, where Pi
becomes a number, and the converting to a univariate polynomial
in Pi screws up.
* better support for mapping numeric arguments of Cos back to the
0 to Pi range.
* made rules that are always true a little faster.
* fixed bug with Gcd when passing floating point numbers.
Reported by Fredrik Noring.
* Small change to proteus (Mark).
* Added example "MinimumSpanningTree".
* Bug fix: interpreter crashed if a function refers to another
function which gets redefined.
* Bug fix: Limit(x,Infinity) going wrong on -Infinity/Infinity.
* added Integrate(var)(function) which returns the antiderivative
of a function. Suggested by Christian Obrecht.
* Fixed "gnuplot" (broken due to the changed functionality of
N(..) ).
* Fixed bug: CanProve(P Or (Not P And Not Q)) returned the wrong
answer. Reported by Vladimir Livshits.
* Fixed bug: Cos(0) wasn't evaluating to 0 any more.
* improvements to documentation.
* Derivatives now better threaded.
* fixed compiler warnings: anumber.cpp under Windows compilation
(reported by Vladimir), Proteus warnings under Debian (Reported
by Gopal).
* removed -g option for compilation. Made executable seriously
smaller.
* Much improved Limit, thanks to Christian Obrecht.
* Small improvements to Proteus.
* pretty printing of vectors and matrices.
* Limits can now deal with direction (limit from Left or Right).
* PSolve for 3rd degree fixed by Robert.
* Added operators /: and /:: .
* Incorporated the changes for complex numbers Christian sent in.
Arg now implemented correctly.
* better numeric Ln and ArcTan.
* functions that are not defined yet are now returned with their
arguments evaluated. Eg f(2+3) returns f(5) in stead of f(2+3).
