I am happy to announce a new *alpha* release of 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.
I get errors when trying to use a mem file different from plain. The 
following:

beginfig(0);
   path p; p := unitsquare xscaled 3cm yscaled 3cm;
   circular_shade(p, 0, yellow, red) ;
endfig;
end.

compiled with

mpost -mem=metafun test.mp

results in a segmentation fault and an emtpy log file.

And trying to typeset a MetaFont file with

mpost -mem=mfplain test.mf

produces the following error:

This is MetaPost, version 1.501 (kpathsea version 6.0.0dev)  26 JUL 2010

I have just compiled mpost from source and moved it inside the TeX Live 
distribution. I have not re-built any format file as I have understood 
that they are not used any longer.
