MetaPost 1.770 (test release)
by Taco Hoekwater 10 Dec '12

10 Dec '12

We are happy to announce a new test release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.770 ---------------------------------------------------------------------- This is a test release for the new functionality planned in MetaPost 1.800. This version will not be uploaded to CTAN / TLcontrib yet. The plan is to wait for a few weeks before releasing 1.800. That will then be an official end-user release. Bugs in the current version are expected, so use with care! The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/gf/project/metapost/ ---------------------------------------------------------------------- What is new in MetaPost version 1.770: ---------------------------------------------------------------------- Fixes & improvements: * There is a new bitmap backend: outputformat:="png"; This backend uses cairo and libpng to generate PNG bitmap data. Associated with this, there are new internals "hppp" and "vppp", that are used by the bitmap backend to decide on the scale of the generated bitmap. Default value for both new internals is "1.0", i.e. one pixel per Metapost point. * On the command line, adding --numbersystem="double" switches to double precision floating point internal numerical values instead of the traditional scaled point. There is also an identically named new read-only internal to query the current setting. The possible return values for that are currently "scaled" and "double". With "double" in effect, numerical values can be expressed in scientific notation including exponent, e.g.: a = 23.5E71; and the warning limit (traditionally 4096.0) has been extended to allow for the greater range. * The C API has been extended to allow path control point resolution without going through the Metapost input language, see manual/mplibapi.tex for details. * The C API has been extended with a "math_mode" switch in the options structure, and the memory size options as well as "ini_mode" have been removed (the MPlib instance now always starts up in inimp mode) * The code for picture shipout now uses "double" for all floating point values. This can give small differences in the actual output files in traditional mode due to the required scaled -> double conversion, but was necessary to support the new numerical backend code. * The Lua API internals have been updated to reflect the C API changes. * All known crashes in earlier versions of Metapost have been fixed. Known issues: * The manual is not up-to-date yet on the metapost input language changes. * There are various small memory leaks (for the most part, these were already present in mpost 1.50x series). ---------------------------------------------------------------------- Legal notice / license / bug reports ---------------------------------------------------------------------- MetaPost is a system for producing graphics developed by John Hobby at AT&T, based on Donald Knuth's Metafont.

by Taco Hoekwater 10 Dec '12

10 Dec '12

Hi, I have just uploaded the archives for a new luatex release, 0.72.0. This release exists mostly to get back into the habit of releasing, you can expect another release in a month or so. There are a few small improvements, but not that many bugs fixed yet in this version. Most noticeable changes: * update various used libraries, including mplib 1.770, poppler 0.21, libpng 1.5, and lpeg 0.10.2. * new 'pdfscanner' lua library. * various OT math fixes, including \Umathcharnumdef. * improved placement of bottom accents. * various other small fixes that have accumulated over the past year-and-a-half. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.72.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
