The MetaPost team is happy to announce the release of a new beta:
----------------------------------------------------------------------
MetaPost 0.893 (beta for 0.9)
----------------------------------------------------------------------
This is a public beta release for the upcoming version 0.9. The
sources and a win32 package can be downloaded immediately from
http://sarovar.org/projects/metapost/
The source package should compile normally on all systems that are
capable of compiling a modern web2c-based TeX distribution.
The win32 package is intended for fptex or a similar web2c-based
installation, and has been tested only with TeXLive 2003. The
executables will *not* work for miktex, sorry.
After beta testing, this version will hopefully become the next
official release of MetaPost, at the end of April 2005. That is
roughly two weeks from today, so test reports are very welcome.
Of course, we welcome any comments (either good or bad) that you may
have. Simply replying to this message is fine, but see the bottom of
this message for a more formal way to report bugs and feature requests.
For those of you who have noted the large gap between 0.641 and 0.9:
We have deliberately chosen to step over some minor version numbers,
such that the first major release by the current team (this release
is planned for the autumn of 2005) can become version 1.0 without
causing additional confusion.
----------------------------------------------------------------------
What is new in version 0.9:
----------------------------------------------------------------------
1. There is a new internal quantity called mpversion that reports the
current metapost version, and the version information is also written
to the PostScript file.
2. The LaTeX sources of the mpman, mpintro, and mpgraph manuals have
become part of the distribution package.
3. TEX.mp now has TeX format support through a pair of macros called
TEXPRE() and TEXPOST(). This llows you to process the contents of
the TEX() macro with, for example, LaTeX (instead of plain TeX).
An example is given in the manual.
4. metapost now writes a %%HiReSBoundingBox comment
5. The EPS output no longer contains actual spaces within PostScript
strings as for example output by label("a space"), but their
octal escape (\040) instead.
6. The EPS output now also has a %%BeginProlog DSC comment
as well as %%EndProlog
7. The comments in the Web source have been changed to point out
that on modern machines, acquiring the random seed has actually
become a system-dependant operation (a granularity of whole seconds
is not small enough on new machines).
8. The 'newer' command now accepts more than 2 arguments, testing
each of the files in turn.
----------------------------------------------------------------------
Bugfixes in version 0.9:
----------------------------------------------------------------------
1. Documentation improvements: all known errata and typos have been
removed, better explanations of e.g. dash patterns and dotlabel have
been provided, and a number of omissions has been rectified.
2. The BoundingBox was not computed correctly when a filldraw command
with a noticeable pen size was used at the edge of the picture.
3. Paths starting with degenerate constructions like (0,0)--(0,0)--(0,0)
could overflow memory.
4. The PostScript output could accidentally contain 8-bit characters
within PostScript strings in previous versions because a test was
shared between terminal printing and PostScript printing.
5. A bug has been found in the assignment of serial numbers to
independant variables in metafont 2.71828. This bug affected MP as
well, and the same patch has been applied.
6. The turningnumber was sometimes wrong in unexpected ways. The new
implementation is still sometimes wrong (when there are strange path
segments involved), but in a much more predictable way: the new code
always draws straight lines between the actual points, and calculates
the turningnumber based on that path instead of the actual path. The
effect is that cusps and loops within segments are now completely
ignored. A more thorough fix of turningnumber is planned for the
next release.
7. There was an 'off by one' error in dvitomp wrt. the interpretation
of virtual fonts.
8. mpto uses a new TeX macro for the generation of labels, making it
more robust wrt. strange user code within the actual label text.
9. A missing colon in boxes.mp has been added
10. A missing save in mfplain.mp has been added
11. The generisize in boxes.mp has been fixed so that it now accepts
[[ as a valid variable name
