** Added an error check to trap multifit calls with fewer observations
than parameters. Previously calling the multifit routines with n<p
would cause invalid memory access.
** Added the Debye unit to physical constants.
** Added cumulative distribution functions for the discrete
distributions, including binomial, poisson, geometric, negative
binomial, pascal and hypergeometric.
** Added the functions gsl_cdf_beta_{Pinv,Qinv} and
gsl_cdf_fdist_{Pinv,Qinv} for computing the inverse of the cumulative
beta and F distributions.
** Added the multilinear fit estimator function gsl_multifit_linear_est
for computing model values and their errors.
** Avoid division by zero in gsl_multimin_fdfminimizer_vector_bfgs
if the step-size becomes too small.
** Users on DEC Alpha systems will need to specify their desired IEEE
arithmetic options via CFLAGS when building the library, as these are
no longer added automatically.
** Added new random variate generators gsl_ran_gaussian_ziggurat
and gsl_ran_gamma_mt for the Gaussian and Gamma distributions based on
the Marsaglia-Tsang ziggurat and fast gamma methods.
** Improved the speed of the exponential power distribution
gsl_ran_exppow.
** Improved the speed of the Gaussian ratio method by adding quadratic
bounds in gsl_ran_gaussian_ratio_method.
* statistics/regress: new function
* general bug fixes and improvements (see ChangeLog for details)
* audio/waveread: big-endian fix; 2-channel file fix
* comm/galois: fix rank calculation for galois array
* general/interp2: cubic interpolation
* image/: return MxNx3 matrices of appropriate numeric class
* io/textread: faster
* io/dlmwrite: control precision and line separator; allow append
* miscellaneous/mfilename: compatibility function
* miscellaneous/listen: subnet patterns; loopback support
* NaN/xcovf: missing data xcorr
* octcdf/: support for netcdf files
* optim/wpolyfit: return row vector; allow centering and scaling
* plot/legend: fix error on first call
* plot/print: add PDF option
* signal/residued,residuez: partial fraction expansion of filters
* signal/qp_kaiser: PPN filter bank coefficients
* statistics/histfit: allow negative data

* tsa/: improved speed, style and docs
* tsa/amarma: adaptive mean ARMA modeling
* tsa/y2res: add entropy estimation; add equidistant quantisation
* tsa/mvfreqz: add PDCF
* support for 2.9.4
* support for 64-bit indexing
* support for MinGW build
* Avoid floating point overflow and underflow
* Do not use "Read Precision" in plot
* cos(x*pi*rad) equals 1 if x is even, not -1
* isodate(), localdate(), timestamp(), stamptodate() functions
* Fix show ending zeroes
* Fix prefixes with automatic simplification/factorization
* Approximate comparison
* ...and some more...
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries. From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.
Algorithmic changes
* Considerably improved performance of number input.
Changes 1.1.10:
Implementation changes
* Removed the vptr of modular integer and univariate polynomial
classes in order to fix some crashes in that sector of CLN. Code
using this needs to be recompiled.
* Many more operator signatures make the integration of CLN types with
float/double easier.
Other changes
* Several compilation fixes.
* Made it possible to cross-compile CLN.
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).

modes. Otherwise display a dialog warning the user that the
current calculation will be cleared.
Incompatible modes are:
Scientific -> Basic

This fixes info-file-related PLIST problems.
it is broken on 3.0, and makes the compilation fail on -current,
because the name of the dynamic library is transformed by bl3

2.13 April 20 2005 - Minor

2.01 May 27 2004 - Major
This version is a MAJOR revision to Spreadsheet::WriteExcel. The
format of the Excel file that it produces has been updated from
Excel 5 to Excel 97. This allows support for long, 32k character
strings and Unicode.
DUE TO THE MAJOR INTERNAL CHANGES IT IS RECOMMENDED THAT YOU TEST
THIS UPGRADE FULLY BEFORE DEPLOYING IT.
Also note that this version can be 1.5 to 2 times slower than
previous versions and the write_comment() method has been
temporarily removed. These issues will be fixed in later releases.
+ Changed the default Excel format to Excel 97.
+ Added support for strings up to 32767 character.
+ Added support for Unicode strings.
+ Improved speed in relation to pre-release versions.
However, it is still slower than the 1.xx versions.
+ Improved OpenOffice.org support.
+ Added more examples: diag_border.pl, indent.pl,
unicode.pl, unicode_japan.pl, unicode_list.pl
+ Changed the distro dir structure.
- Temporarily removed write_comment() support since the Excel 5
version isn't compatible with Excel 97+.
1.01 May 24 2004 - Minor
! Small non-bug fix to write_comment().
0.43 April 28 2004 - Minor
! Fixed longstanding bug where page setup features didn't
show up in OpenOffice.org.
! Fixed localised @_ bug when using threaded perls.
Thanks Tamas Gulacsi and Stephan Loescher.
0.42 August 26 2003 - Minor
! Fixed bug when using IO::Sclalar object as a filehandle.
Thanks to Kyle R. Burton and David Robins.
! Fixed minor formula parser bug.
Thanks Michael Braig
! Fixed handling of column sizing for widths less than 1
unit (again). Thanks to Rubio (again).
! Failed new() returns undef instead of croak()ing as per docs.
makeinfo if no native makeinfo executable exists. Honor TEXINFO_REQD
when determining whether the native makeinfo can be used.
* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.
* Get rid of all the "split" argument deduction for makeinfo since
the PLIST module already handles varying numbers of split info files
correctly.
NOTE: Platforms that have "makeinfo" in the base system should check
that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
correct.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
