I am happy to announce a new *alpha* release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.500 ---------------------------------------------------------------------- The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/gf/project/metapost/ This is an *alpha* release following a major internal rewrite, so do not use this version for production purposes, but please test with as many files as you can. The win32 binary is intended for texlive or a similar web2c-based installation, this executable will *not* work for miktex. 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 the message for a more formal way to report bugs and feature requests. ---------------------------------------------------------------------- What is new in MetaPost version 1.500: ---------------------------------------------------------------------- * Actual memory dump files do not exist any more. --mem=<MEM> and all other methods of supplying a MEM file are now interpreted somewhat like this pseudo-metapost-code: begingroup; let dump = end; input MEM[.mp]; endgroup; this process is supposed to be transparent besides the facto that there is some extra terminal output and logging. * All memory is now allocated and freed dynamically. There are only two remaining overflow errors(1): "expansion depth" : this is a guard against infinite recursion, the value is 10000. "sizes per font" : this is maxed out for data-structure reasons, the value is 32767. from texmf.cnf, now only the "error_line", "half_error_line" and "print_line settings" are used. (1) but now you can reach the operating system limits, of course. * As this is an alpha release containing lots and lots of new code, MetaPost starts up with the internal equivalent of 'loggingall;' in effect. This results in log files that can help in debugging. * Expect bugs and (minor) memory leaks. ---------------------------------------------------------------------- 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.
