PRNG is a collection of portable, high-performance ANSI-C
implementations of pseudorandom number generators such as linear
congruential, inversive congruential, and explicit inversive
congruential random number generators (LCG, ICG and EICG, respectively)
created by Otmar Lendl and Josef Leydold.
* The PCRE library has been updated to version 8.00.
* R CMD INSTALL has new options --no-R, --no-libs, --no-data,
--no-help, --no-demo, --no-exec, and --no-inst to suppress
installation of the specified part of the package.
* The documented line-length limit of 4095 bytes when reading
from the console now also applies also to parse(file="")
(which previously had a limit of around 1024 bytes).
* A Bioconductor mirror can be set for use by setRepositories()
via the option "BioC_mirror".
* Double-clicking in a tk_select.list() list box now selects the item
and closes the list box (as happens on the Windows select.list() widget).
* configure will be able to find a usable libtiff in some rare
circumstances where it did not previously (where libtiff
needed to be linked explicitly against -ljpeg).
* Making refman.pdf works around a problem with the indexing
with hyperref 6.79d and later.
* The 'extended' argument is deprecated in strsplit(), grep(),
grepl(), sub(), gsub(), regexpr() and gregexpr() (not just the
value extended = FALSE) and will be removed in R 2.11.0.
* bug fixes
per update request from Wen Heping by PR#42755.
Pkgsrc changes:

Changes:
--0.14--
Released February 5, 2010
General changes:
* Fully separated the code into "low-level" and "high-level", permitting the
use of alternative contexts (the mpmath.mp object provides the default
implementation)
* Implemented a context for fast double-precision arithmetic using Python
types (mpmath.fp)
* Implemented hooks for importing a faster version of mp arithmetic from Sage
* Implemented optimized fp versions of certain functions (including erf, erfc,
gamma, digamma, ei, e1)
* Renamed and reorganized various internal modules and methods (including
merging low-level modules into mpmath.libmp). This should not affect most
external code using top-level imports.
Plotting:
* Implemented splot() for 3D surface plots (contributed by Jorn Baayen)
* Permit calling plot functions with custom axes (contributed by Jorn Baayen)
Matrices:
* Fixed lu_solve for overdetermined systems (contributed by Vinzent Steinberg)
* Added conjugate matrix transpose (contributed by Vinzent Steinberg)
* Implemented matrix functions (expm, cosm, sinm, sqrtm, logm, powm)
Miscellaneous:
* Prettier printing of numbers with leading zeros at small precisions
* Made nstr pass on kwargs, permitting more formatting options
* Fixed wrong directed rounding of addition of numbers with large magnitude
differences
* Fixed several docstring typos (contributed by Chris Smith)
* Fixed a bug that prevented caching of quadrature nodes to work optimally.
Special functions:
* Implemented fast evaluation for large imaginary heights of the Riemann zeta
function, Z function and derived functions using the Riemann-Siegel
(contributed by Juan Arias de Reyna)
* Unified the zeta() and hurwitz() functions, automatically selecting a fast
algorithm
* Improved altzeta() to fall back to zeta() for large arguments
* Fixed accuracy of zeta(s) for s ~= 1
* Implemented exact evaluation of Euler numbers (contributed by Juan Arias
de Reyna)
* Implemented numerical evaluation of Euler numbers and Euler polynomials
(eulernum(), eulerpoly())
* Fixed bernpoly() and eulerpoly() to compute accurate values for large
parameters
* Fixed accuracy problems for hypergeometric functions with large parameters
* Faster evaluation of hypergeometric series using on-the-fly code generation
* Optimized hypercomb to detect certain zero terms symbolically
* Removed the djtheta function (jtheta() accepts a derivative parameter)
* Implemented li(x, offset=True) to compute the offset logarithmic integral
* Fixed wrong branch in Lambert W function for certain complex inputs
* Implemented the reflection formula for the Barnes G-function,
superfactorials, hyperfactorials, permitting large arguments in the left
half-plane
* Implemented analytic continuation to |z| >= 1 for hypergeometric functions
pFq with p=q+1; added hyp3f2()
* Implemented Borel summation of divergent pFq functions with p > q+1
* Implemented automatic degree reduction of hypergeometric functions with
repeated parameters
* Added convenience functions expj(), expjpi()
* Use Mathematica's convention for the continuation of the Meijer G-function
* Added phase(), polar(), rect() functions for compatibility with the
Python 2.6 cmath module
* Implemented spherical harmonics (spherharm())
* Optimized ci(), si(), chi(), shi() for complex arguments by evaluating
them in terms of ei()
* Optimized hyp2f1 for z ~= -1
0.16.1

- Fix bug: toRoman() used $this although it's static
- Add unit tests
1.0.1
- Added support for lowercase input/output
- Starting with this release conversion is supported from integers up to
5 999 999 and from the equivalent Roman Numerals
- Added an optional HTML tag to disply roman numerals over 4000 in an
historically accurate fashion
- General fixes and code rewrite maintaining backward compatibility
pkgsrc changes:

- Disabled support for plotting from perl (missing upstream support)
Upstream changes:
2.01080601+
Add 5.005-new keywords to Makefile.PL.
Consistently put space after -I in C include paths (needed???).
Nicer output when debugging faulty LWP and Net::FTP.
Make test engine look in */32/* directory too on 64-bit builds.
Remove POD ornaments to make ABSTRACT_FROM work.
2.01080601++
Reword warning about slow intnum: only 75% longer than on PARI/GP.
(overhead of the internal sub call in subtest 30 looks like 10x
overhead of an empty subroutine call).
New advice that upgrade to 2.3.* may fix `overflow' and `highremainder'.
Exchange order of initialization of PARI and of `functions_highlevel'
with >= 2.3.0; allows installation of highlevel functions
(in particular, install() and PostScript printing).
New function have_graphics() (not exported).
The test engine takes into account have_graphics().
2.01080602
If AUTOMATED_TESTING, delete (bogus?) environment variable DISPLAY.
If AUTOMATED_TESTING, report results of failing tests on STDERR.
Make test suite report rough run times for successful subtests.
2.01080603
Fix misprint and change die() to warn() on failure of $ftp->quit...
Add some void's in Pari.xs.
UNDONE (wrong): Protect init_graph() by NO_GRAPHICS_PARI (in restart code);
include rect.h instead...
sv2pari(),sv2parimat(): a stupid compiler might guess we don't return value...
when patching, use && instead of ; in the shell command
New function Math::PariBuild::patch_args()
Math::PariBuild::patch_pari() supports option --binary, \ as directory
separator in command processor.
Make uname parser recognize i686-pc as ix86.
Generator of function descriptors could try to regenerate existing file.
nok_print() in Testout.pm was defined too late.

New items in core:
* general mechanism for functions to distribute over operators
(distribute_over declaration)
Other revisions:
* improved Laplace transforms of special functions
* assume database:
The inferences between the declarations of variables as integer,
real, complex, .. have been cut out. The constant %i is declared
to be imaginary. The constants %pi, %e, %gamma, %phi are declared
to be real.
The database handles expressions with constants more completely.
Facts like assume(x < %pi/2) are now handled correctly.
The sign of sums of constant expressions is determined more
correctly.
Askinteger take into account more facts from the database.
* improvements of special functions:
More functionality for the Hankel 1 and 2 functions:
Expansion for a half integral order has been implemented.
More consistent numerical evaluation of Bessel and Hankel functions.
More general integrals for Bessel functions and implementation of
integrals for the Airy functions.
Gamma function accepts a Taylor expansion as an argument.
Implementation of Struve H and L functions:
Numerical evaluation for real and complex numbers in float and
bigfloat precision. Handling of specific values. Derivatives of the
functions and expansion for a half integral order is implemented.
Adding mirror symmetry for the Airy functions.
Improving the limits of the log and factorial functions.
* package fft: revised for greater speed
* package to_poly_solver: improvements
* regularize error and warning messages, and translate via gettext (ongoing)
* bug fixes and other improvements in plotting code
* bug fixes in translator
