! Changed OLE container stream name from "Book" to "Workbook"
for compatibility with some third party apps.
Thanks Wieland Pusch and Kevin McMahon.
! Fixed bug that caused all worksheets to be selected in
OpenOfficeOrg causing strange linking of data between
Worksheets. Thanks M. Brodbelt. See

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.
Changes since 12.5.8:
- Bug fix for nintegrate command. Result was correct but not fully reduced.
- Added "twin" option to "primes/matho-primes", removed "primes/matho-twin".
- Automatically determine the variable if none is specified
with the derivative and taylor commands.
- Increased the maximum variable length to 1000 characters.
- Enhanced factorization, with square free factorization of rational multivariate polynomials
- New simplification using the enhanced factorization
- Much more efficient determinant and matrix inverse calculation
- Greatly enhanced and reworked solving of equations and inequalities
- More efficient evaluation avoiding recalculations
- Generally enhanced and more correct algebraic functionality
- Faster calculation of powers with large exponent and base close to one
- Option to automatically simplify or factorize
- Option to warn about denominators assumed non-zero
- Fix negative exponents with lower-case e
- Fix fetching of exchange rates with gnome-vfs < 2.10
- Polynomial functions: coeff(), lcoeff(), pcontent(), degree(), etc.
- Fix ln(e^x)
- Display "x < 3 && x > 1" as "1 < x < 3"
- Display "&&" and "||" as "and" and "or" by default
- Fix display of fractions in "Decimal (Try Exact)" mode
- Compile without errors or warnings with -pedantic and -Wextra
- Unicode fixes
- ...and many more minor fixes and enhancements (and probably some new bugs)...
another "final release"
changes:
-__array_data__, __array_struct__ support
-some bugfixes
-Support array interface in objecttype function
-build system improvements
inofficial note:
The default indices of diagonal() and trace() changed, this causes
a selftest to fail. The default indices behaviour is documented, so
it seems that just the selftest is wrong. This only affects arrays with
more than 2 dimensions.
This update fixes various segmentation faults during "make test" (using
pari 2.1.6).
Pkgsrc changes:
- Removed files/Makefile.PL (not used anymore).
Relevant changes since version 2.010501:
========================================
- various 64-bit fixes
- extensive update ot test suite
Changes:
- Doubled the default max expression size. Display current size on
startup.
- Made solve_sub() return -1 for an identity.
- Speedup of the simplify command.
This is a major version release.
changes include:
-Undo/Redo
-support for objects (and indexes!) with more than 2**31 rows
-new datatypes
-improved HDF5 support
-compression support

A MIP presolver were implemented (currently incomplete). It is
used internally in the routine lpx_intopt (see below).
An advanced branch-and-bound solver (the routine lpx_intopt)
were implemented.
The routine lpx_check_int to check MIP feasibility conditions
was added.
The routine lpx_print_mip was changed to print MIP feasibility
conditions.
The built-in functions sin, cos, atan, and atan2 were added to
the MathProg language.
Some typos were fixed.
Thanks to Minh Ha Duong <haduong@centre-cired.fr> (CIRED, CNRS).
* Faster FFTW_ESTIMATE planner.
* New (faster) algorithm for REDFT00/RODFT00 (type-I DCT/DST) of odd size.
* "4-step" algorithm for faster FFTs of very large sizes (> 2^18).
* Faster in-place real-data DFTs (for R2HC and HC2R r2r formats).
* Faster in-place non-square transpositions (FFTW uses these internally
for in-place FFTs, and you can also perform them explicitly using
the guru interface).
* Faster prime-size DFTs: implemented Bluestein's algorithm, as well
as a zero-padded Rader variant to limit recursive use of Rader's algorithm.
* SIMD support for split complex arrays.
* Much faster Altivec/VMX performance.
* New fftw_set_timelimit function to specify a (rough) upper bound to the
planning time (does not affect ESTIMATE mode).
* Removed --enable-3dnow support; use --enable-k7 instead.
* FMA (fused multiply-add) version is now included in "standard" FFTW,
and is enabled with --enable-fma (the default on PowerPC and Itanium).
* Automatic detection of native architecture flag for gcc. New
configure options: --enable-portable-binary and --with-gcc-arch=<arch>,
for people distributing compiled binaries of FFTW (see manual).
* Automatic detection of Altivec under Linux with gcc 3.4 (so that
same binary should work on both Altivec and non-Altivec PowerPCs).
* Compiler-specific tweaks/flags/workarounds for gcc 3.4, xlc, HP/UX,
Solaris/Intel.
* Various documentation clarifications.
* 64-bit clean. (Fixes a bug affecting the split guru planner on
64-bit machines, reported by David Necas.)
* Fixed Debian bug no.259612: inadvertent use of SSE instructions on
non-SSE machines (causing a crash) for --enable-sse binaries.
* Fixed bug that caused HC2R transforms to destroy the input in
certain cases, even if the user specified FFTW_PRESERVE_INPUT.
* Fixed bug where wisdom would be lost under rare circumstances,
causing excessive planning time.
* FAQ notes bug in gcc-3.4.[1-3] that causes FFTW to crash with SSE/SSE2.
* Fixed accidentally exported symbol that prohibited simultaneous
linking to double/single multithreaded FFTW (thanks to Alessio Massaro).
* Support Win32 threads under MinGW (thanks to Alessio Massaro).

link to appear in the tools directory and be picked up and embedded in
one of the installed scripts. Since this package clearly uses gzip at
runtime add an explicit USE_TOOLS+=gzip:run and fixup the gzip path that
gets embedded. Fixes PR pkg/32218. Bump PKGREVISION.
