Some highlights of changes since 4.2.3:
* PCRE updated to 4.3, GD to 2.0.15
* improved Apache2 support
* much improved stream & URL wrapper support, output compression support
* added CLI (Command Line Interface) SAPI
* debug_backtrace() backported from ZendEngine2
* faster build system
* huge number of other bug fixes and improvements
Packaging changes:
* 'pcre', 'xml', and 'session' modules folded back into main package -
'pcre' and 'xml' is required by PEAR, and 'session' is just too essential
to be separate
* 'gd' module now uses bundled PHP GD library, which is better integrated
* PHP modules use shared distinfo when possible to ease future PHP updates
* ${PREFIX}/bin/php is now CLI version, ${PREFIX}/libexec/cgi-big/php
remains CGI version
Clarify that the internal hash as well as the hash builtin
function used by calc, while based on the Fowler/Noll/Vo
hash is NOT an FNV hash.
Made slight performance improvements to calc by an optimization of how
calc's internal hash is computed. The "make chk" regression test
runs about 1.5% faster (when compiled with -O3 on an AMD Athlon)
NO_HASH_CPU_OPTIMIZATION is not defined. Calc's internal hash values
have not changed. By default, NO_HASH_CPU_OPTIMIZATION is NOT defined
and the slightly faster expression is used.
A slight modification of what was known as the "calc new stardard"
configuration (calc -n or config("all", "newstd")) is now the default
calc configuration. The flag:
calc -O
was added to get the old classic calc configuration. The flag command
line flag, -n, now does nothing. Use of -n is deprecated and may go
away / be used for something else in the future.
The following table gives the summary of these changes:
pre v2.11.8 v2.11.8
default pre v2.11.8 -O & oldstd v2.11.8
and oldstd -n & newstd classic cfg default
--------------------------------------------------------
epsilon 1e-20 1e-10 1e-20 1e-20
quo 2 2 2 2
outround 2 24 2 24
leadzero 0 1 0 1
fullzero 0 1 0 0
prompt > ; > ;
more >> ;; >> ;;
With the exception of epsilon being 1e-20, and fullzero being unset,
the new default calc config is like it was (pre-2.11.8) with calc -n /
config("all", "newstd").
The new default config is the old classic config with outround being
24, leadzero being set, and the prompts being ;'s.
* 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.

djbfft is an extremely fast library for floating-point convolution.
The current version holds most of the speed records for double-precision
FFTs on general-purpose computers.
djbfft provides power-of-2 complex FFTs, real FFTs at twice the
speed, and fast multiplication of complex arrays. Single precision
and double precision are equally supported.
- Use omf.mk to handle scrollkeeper omf files properly.
- Depend on gnome2-dirs to handle shared directories.
- Sort PLIST while here.
- Bump PKGREVISION to 1.
* Some speed improvements in SIMD code.
* --without-cycle-counter option is removed. If no cycle counter is found,
then the estimator is always used. A --with-slow-timer option is provided
to force the use of lower-resolution timers.
* Added missing static keyword that prevented simultaneous linkage
of different-precision versions; thanks to Rasmus Larson for the bug report.
* Corrected accidental omission of f77_wisdom.f file; thanks to Alan Watson.
* Removed non-portable use of 'tempfile' in fftw-wisdom-to-conf script;
thanks to Nicolas Decoster for the patch.
* Added 'make smallcheck' target in tests/ directory, at the request of
James Treacy.
Summary of changes for version 2.0.17:
-------------------------------------
This will probably be the last release in the 2.0.x series. There
are a few bug fixes, but the major change is to print a message
saying that Octave 2.0.x cannot be compiled with gcc 3.0.x or gcc
2.96. If you want to build Octave 2.0.x, you will need to use gcc
2.95.x. If you want to use gcc 3.0.x or some later version, you
should be using the Octave 2.1.35 sources or a more recent version.
