I am happy to announce a new test release of MetaPost:
----------------------------------------------------------------------
MetaPost 1.790
----------------------------------------------------------------------
This is a third test release for the new functionality planned in
MetaPost 1.800. Besides a few bug fixes, this version has lots of
internal speed-ups so that its running times should now be comparable
to the MetaPost 1.50x series.
All the reported new bugs in 1.780 have been fixed, but I may have
introduced new problems while adding the speed optimizations. Use with
care, and *do* let me know if something is wrong!
This version will not be uploaded to CTAN / TLcontrib yet. The plan is
to wait another for a few weeks before releasing 1.800. That will then
be an official end-user release.
The win32 binary can be downloaded immediately from files section at
https://foundry.supelec.fr/projects/metapost/
The new foundry software is still not quite up to speed, so there
is no source tarball uploaded yet (it was too large for the web form).
If you want to build this latest MetaPost either wait a few days while
Fabrice fixes foundry, or do an anonymous subversion checkout yourself:
$ svn checkout --username anonsvn
https://foundry.supelec.fr/svn/metapost/tags/1.790
The password is anonsvn
----------------------------------------------------------------------
What is new in MetaPost version 1.790:
----------------------------------------------------------------------
* Lots of speed-ups.
* Fixed bug in division expressions that started with a literal number.
* A few problems with bad deallocations were solved.
* A bug where after saving and redefinition of primitives, they later
were restored to 'undefined' instead of to their primitive meaning.
* The "double" literal number parser now only accepts scientific
notation if the character following 'E' or 'e' is '+', '-', or
a digit.
