Now GLPK supports free MPS format. Two new API routines
lpx_read_freemps (to read problem data in free MPS format) and
lpx_write_freemps (to write problem data in free MPS format)
were added. This feature is also available in the solver glpsol
via new command-line options --freemps and --wfreemps. For more
details see the GLPK reference manual.
API routines lpx_read_cpxlp and lpx_write_cpxlp for reading and
writing problem data in CPLEX LP format were re-implemented to
allow long symbolic names (up to 255 characters).
The following three modules were temporarily removed from the
GLPK distribution due to licensing problems: DELI (an interface
module to Delphi), GLPKMEX (an interface module to Matlab), and
JNI (an interface module to Java).
Algorithmic changes
* Input of numbers in bases 2, 4, 8, 16 and 32 is now done in linear bit
complexity as opposed to O(N^2). Useful for all kinds of persistency.
Implementation changes
* Fixed several bugs in the integer input and output routines that could be
blamed for random crashes in the following cases: output in base 32 for
quite large numbers, input in base 2 for fixnums and input in base 3 for
fixnums on a 64 bit target.
* Fixed crash when radix specifiers were used in input streams.
* Speed up on x86_64 and ia64 by adding some inline assembly.
Other changes
* Fixes for compilation on MacOS X and little endian Mips.

script. This is needed if you want to use mkoctfile once the package is
installed. For example, on NetBSD-1.6* systems, it is important to point
to the gcc3 package tools instead of the base system compilers.
It is small and simple to use but with much power and versatility underneath.
Features include customizable functions, units, arbitrary precision, plotting,
and a graphical interface (GTK+) that uses a one-line fault-tolerant expression
entry (although it supports optional traditional buttons).
Changes 2.0.1:
This is a maintenance version mainly to fix a number of minor bugs and
issues. Some rather nasty bugs were Windows-specific.
Changes 2.0.0:
Many things have changed since 1.0. The R language has acquired namespaces,
exception handling constructs, formal methods and classes, much improved
garbage collection, generalized I/O via connection objects, and
considerable improvements in the graphics area. The user workspace has been
reorganized, and so has the set of packages that ship with R. Several
"recommended packages" deemed indispensable in a statistical system are
bundled. In addition, there has been a large number of more specific new
functions, tweaks, and bugfixes.
Changes:
- Using "memmove()" instead of deprecated "bcopy()".
- Added "tests/tutor.in", which is an incomplete Mathomatic tutor.
- Many improvements to scripts in the tests directory.
- Removed "calculate factor" option.
- Code cleanup.
- Added more modulus simplification.
- Simplify ((a%n)*integer+b)%n to (a*integer+b)%n generally and completely.
- real^complex and complex^complex are now approximated.
Changes:
- Removed obsolete short variable name code and bumped up "MAX_VARS" to 500.
- Fixed problem with conflicting names and code for "cpow()" and "cexp()".
Renamed to "complex_pow()" and "complex_exp()".
Unfortunately, guile{,14}/buildlink3.mk directly includes it, and I don't
know which dependencies actually need libltdl, so it was a recursive bump.
Hopefully this recursive inclusion can be ripped out of
guile{,14}/buildlink3.mk at some point and bubble down to dependencies that
actually use libltdl, avoiding this headache in the future....
Changes:
- Added "code integer" command, which outputs working C code with integer
variables.
- Changed makefile to use libncurses instead of libcurses.
- Added more simplification rules for modulus.
as it's only used internally by bsd.prefs.mk.
* Make _PKGSRCDIR a public variable by renaming it to PKGSRCDIR.
Also, generate its value from ${_PKGSRC_TOPDIR} so it's less fragile
than the old method of stripping off the last two components of
${.CURDIR}. PKGSRCDIR may now be used after bsd.prefs.mk is defined.
* Change all references to _PKGSRCDIR to PKGSRCDIR.
Changes:
Changed sum and product commands to not create another equation if the
result is a constant. If the result is a constant, it is just displayed.
Mathomatic now approximates -1^(2^.5) and the like.
Added modulus (%) operator.
Added simplification of univariate modulus expressions.
Changed univariate modulus simplification to multivariate, integer only
simplification.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
v4.1
COSMETIC/USABILITY IMPROVEMENTS
- The File->Description dialog now updates automatically if you leave it open
while loading a new pattern file. Also, any previous description dialog is
closed when you open a new one.
- GtkLife now issues a warning dialog if it appears the application was not
propery installed (i.e., "make" without "make install").
- GtkLife now issues a warning dialog if the configured pattern collection
is not found.
BUG FIXES
- Fixed a bug that prevents the start/stop button from changing color when
Gtk+ has debugging enabled (thanks to James Gregory for reporting).
- Fixed stair-stepping effect when drawing diagonal lines.
MISCELLANEOUS
- Better ChangeLog :-)
v4.0
NEW FUNCTIONALITY
- The world size has been bumped up to 1 million x 1 million.
- Added View->Find Active Cells, to locate a live (and preferably active)
region and center on it.
- gtklife has a new default file format, GLF, which is similar to RLE.
- gtklife can now handle multiple file formats: Life 1.05 (the original
format), Life 1.06, RLE, XLife, and GLF. File type is auto-detected when
loading. Information on file formats was added to the "File Handling"
section of the documentation, and a page was added giving detailed
information on the GLF format.
- You can now set a per-session pattern directory
(File->Change Pattern Collection) as well as a default pattern directory
(Preferences/File/Default Pattern Collection).
- Sidebar patterns can now be bundled into sub-directories. Directories will
be displayed with trailing slashes. Click on a directory name to display
its contents in a clickable list beneath the sidebar.
- You can now specify a pattern collection directory on the command line
(previously only individual patterns could be loaded via command line).
- The pattern description has been made unbounded in length and width. An
error will occur if you attempt to save a pattern with a too-large
description to a LIF or RLE pattern file.
COSMETIC/USABILITY IMPROVEMENTS
- Mouse wheel over the description text box now scrolls the description
(previously you had to hover the mouse over the scrollbar).
- The color picker in Preferences now uses the contents (if any) of the
corresponding text entry as its starting color.
- Recent files in the File menu now display full path as a tooltip.
- Sidebar scrollbar is now only displayed when needed.
PATTERN COLLECTION CHANGES
- A new pattern collection, JSLife by Jason Summers, is now available as an
option. The sidebar can be set to display the original LifeP, JSLife, or
a custom collection of your own.
- Patterns were reorganized into a hierarchical format.
- Patterns were renamed to be more human-readable.
- Patterns were converted to GLF for speed of loading.
- Pattern descriptions were reformatted.
- Paul Rendell's Turing Machine pattern was added to the LifeP collection.
- Added a longer description to the Unit Cell pattern.
- Now that we have a command to locate active cells, re-centered the Jaws
pattern.
- Note: Due to a minor change in the config file, any custom pattern
directory that you have chosen previously will be reset.
DOCUMENTATION IMPROVEMENTS
- Fixed broken link to the Scientific American article in help.
MISCELLANEOUS
- The install process now deletes any existing patterns bundle before copying
over the new patterns.
- Added new nifty program icons based on the "pulsar".
Changes since 11.3c:
Improved eliminate command error handling.
Added "eliminate all" command.
Code cleanup.
Man pages for the prime number tools were contributed
by David Moreno Garza. Many thanks.
Renamed the Mathomatic directory in the source tarball to
"mathomatic-`cat VERSION`".
Added several comments to the source code.
Renamed prime number tools to "matho-*".
Improvement to full simplification.
Tried something new with uf_simp() that fixed a problem with Mathomatic
solve complicating expressions.
Minor bugfix to eliminate command.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
This release adds changes to better support compiling under cygwin,
improved custom function support, including the addition of the
pmodm127 example and config("compile_custom") and config("allow_custom")
calls, and a missing display help file. It fixes configuration
state hashing, document typos, calc -d (to disable printing of the
leading ~), and some compilation warnings reported under OS X.
installed files.
- libtoolize a few more lines which seem to have been missed in the original
libtoolization.
- enable loading of shared objects which lets the various .oct files installed
by octave-forge actually work instead of just the .m files.
