We are happy to announce a new test release of MetaPost:

----------------------------------------------------------------------
MetaPost 1.780
----------------------------------------------------------------------

This is a second 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 still likely, 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 1.780:
----------------------------------------------------------------------

* The turningnumber calculation in 1.770 was bugged.

* The picture export in 1.770 forgot to add trailing zeroes to the
   log and term output channel resulting in rubbish output.

* The arguments of the PS "dtransform" operator have been fixed
   (was wrong since 1.750).

* The warning limit in numbersystem=double mode is now exactly 2**52.

* A bunch of obvious memory leaks fixed. Not all yet, but now the
   MPlib seems to be usable even with many graphics.
