* What is new in gsl-1.4:
** Added cumulative distribution functions and their inverses for the
continuous random distributions including: gaussian, lognormal, gamma,
beta, cauchy, laplace, chisq, exponential, gumbel, weibull,
F-distribution, t-distribution, logistic, pareto and rayleigh.
** Added faster binomial random variates using the TPE rejection
algorithm, in the function gsl_randist_binomial_tpe.
** Added new functions gsl_rng_fwrite and gsl_rnd_fread for storing
the state of random number generators in a file.
** Added a new function gsl_combination_memcpy()
** Corrected values of electrical constants in CGS units. To take
account of different electrical systems of units the values are now
prefixed by GSL_CONST_MKSA (for the SI Metre, Kilogram, Second, Ampere
system) or GSL_CONST_CGSM (for the Centimetre, Gram, Second, Magnetic
system with the Gauss as the fundamental unit of magnetic field
strength). The previous GSL_CONST_MKS and GSL_CONST_CGS prefixes have
been removed, as have the permeability and permittivity constants in
the CGS system since this uses different defining equations.
** Fixed bugs in the random number generators gsl_rng_fishman18,
gsl_rng_fishman2x, and gsl_rng_knuthran2 which caused them to return
incorrect results. Minor corrections were made to the parameters in
the other Knuth generators borosh13, coveyou, fishman20, lecuyer21,
and waterman14.
** Fixed a missing transpose bug in the gsl_linalg_QR_QRsolve
and gsl_linalg_QRPT_QRsolve routines which were computing the
solution to Q^T R x = b instead of Q R x = b.
** Fixed gsl_sf_gammainv to return zero instead of a domain
error for arguments corresponding to singularities in gamma.
** Fixed a bug in the simplex minimization algorithm which
caused it to fail to find the second highest point correctly
when searching the set of simplex points.
** Fixed a bug in the conjugate gradient minimizers conjugate_pr,
conjugate_fr and vector_bgfs which caused the search
directions to be updated incorrectly.
** Fixed a bug in gsl_sf_psi_1_int(1) which caused it to
return the incorrect sign for psi(1,1).
** Fixed the simulated annealing routine gsl_siman_solve to use the
parameter iters_fixed_T for the number of iterations at fixed
temperature instead of n_tries.
** Fixed a bug in gsl_combination_valid which caused it to return the
incorrect status.
** Fixed a bug in gsl_permutation_canonical_to_linear which caused the
output to always be zero, and the input permutation to be incorrectly
replaced by the output.
** Fixed a bug is gsl_ran_discrete which could cause uninitialised
data to be returned for some distributions.
** Fixed the dependencies for gsl_chebyshev.h to include gsl_math.h.
** Fixed a bug in gsl_complex_arccsc_real which caused it to return
the incorrect sign for the imaginary part when -1<x<0.
** Fixed a bug in the QAWC Cauchy integration routine which could
allow the singularity to fall on an interval boundary, leading to
division by zero.
** Improved gsl_sf_gamma_inc_P(a,x) to avoid a domain error for x<<a
when a>10.
** Improved the accuracy of gsl_sf_coupling_3j for large arguments.
** Improved the performance of gsl_sf_choose(m,n) by separating the
calculations for small and large arguments.
** On platforms without IEEE comparisons gsl_{isnan,isinf,finite} will
fall back to the system versions of isnan, isinf and finite if
available.
** gsl_linalg_householder_hv now uses BLAS routines internally
** The script configure.in is now compatible with autoconf-2.50 and
later.
** Reduced the memory usage of the multifit algorithms from MxM to MxN
for large M by performing the QR decomposition of the Jacobian
in-place.
** IEEE modes now use the C99 fenv.h functions when platform spectific
functions are not available.
This is a Ksi (Ksi Scheme Interpreter), a portable,
embeddable Scheme implementation written in C.
Ksi provides a machine independent execution platform that
can be linked in as a library when building extensible programs.
And what is more important it is not a Guile. :-)
New features in chemtool 1.6
- universal import mode based on BABEL (both openbabel and babel supported)
- Formula weight calculator now handles all main group elements and the first
row of transition elements, and accepts greek phi as phenyl substituent.
- Movable hexagonal or square grid backdrop
- Improved SVG export, optional preview bitmaps in EPS export, optional EMF
export
- Cursor key support for pixel-precise drawing and moving
- The cleanup function now corrects bonds that deviate from ideal
horizontal or vertical orientation by a single pixel
- Color support (bonds and text can be red,green,blue,cyan,magenta or yellow).
- Default bond length now configurable, additional grid positions at two and
three times this length added
- Added a brief help text to accompany the 'About' window in the 'Help' menu.
- Added alternate text font (Times Roman)
- An attachment site can be marked before saving a molecule or fragment,
which act as reference point for adding this fragment to other molecules
(previously, this had to be the first atom in a file). Attachment sites are
marked in the preview window by a small x.
- Background color can now be chosen for screen display and EPS export, and
drawing whiteout boxes under labels is now an option ( off by default !).
- Text at 8,10,12,14,17,20 and 24pt can now coexist in a drawing.
- Increased allowed label length to 100.
- Improved rendering of dashed wedge and dotted lines
- Improved text kerning in xfig-based print and export.
- It is now possible to place an auto-incrementing counter at the cursor
position for numbering sites.
- Changed double bond drawing code to no longer switch sides depending
on drawing (or rotation) angle. (As a result of this, some older drawings
will need fixing)
- Rescaling a molecule now also scales its labels. Downscaling beyond
zero size (causing strange inversions) is no longer possible.
- Renamed the "Orbitals" template menu to "Symbols" and added "plus",
"minus" and a rearrangement arrow to it.
- Added two new bond types, a triple bond with all three lines equal,
and a quadruple bond.
Changes:
(Exceptions): A catch clause like `CATCH T(e):' introduces a read-only
variable `e' of type `T' within the block. The `(e)' part is
optional. New method Name() and new procedure Abort(). FatalError()
now takes a message string as argument.
(Object): The functions NewUCS4Region() and NewUCS4() have been
revived.
(ADT:ArrayList): New methods Sort() and Elements().
(ADT:StringBuffer): Now provides an INIT() method, covering the
functionality of the old NewCapacity() constructor. New method
CharsUTF16().
(ADT:Comparator): Provides a comparator class `String'.
(oo2c): Super calls can be issued for all type-bound procedures of the
base type, instead of just the procedure that is currently being
redefined.
(oo2c): The compiler warns if an INIT() method does not call the
INIT() of the base type.
Plus the usual number of bug fixes...

handling of special variable and value arguments
in user defined functions)
