Hmm, can someone give me a sign when this has been added to TL?

> The MetaPost team is happy to announce a new release of MetaPost:
> ----------------------------------------------------------------------
> MetaPost 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. These
> executables will *not* work for miktex, sorry.
> 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
