Release of version 1.0.45 (Februari 22nd 2001)
* Fixed bug: Floor or Ceil working on 0.5 would result in an
infinite loop.
* Started work on solving differential equations
(scripts/odesolver).
* Some bug fixes thanks to Robert V Schipper.
* Some bug fixes on limits involving infinity, due to Mark
Arrasmith.
* Bug fix: Decimal didn't work correctly on negative numbers.
Reported by Gopal Narayanan (Debian Yacas package maintainer).

Release of version 1.0.44 (December 30th 2000)
* Unfenced the if and else operators.
* Implemented first installment of RadSimp
* Yacas can now do 39 of the Wester benchmark calculations (up
from 25).
* Updated Psion organizer version (EPOC32).
* Added derivatives and antiderivatives of Sign,Abs and if .. ..
else .. constructs.
* fixed two bugs that caused Div(x+1,x) to not work immediately
after startup.
* Integrating (a*x)^(fraction) not working, but (a*x)^(integer)
did.
* improved some complex number functionality, Sin/Cos
calculations.
* gcd, div, mod fix for rational numbers.
* Continued fraction expansion of polynomials, DivPoly which does
an efficient division of polynomials, returning a polynomial.
* small cleanup of the code
* added functions: Pslq, Floor, Ceil, Round, IsHermitean,
IsUnitary
