It is my great pleasure to announce the availability of MonetDB 4.12.0
and its accompanying SQL 2.12.0 and XQuery 0.12.0.  This release is the
next step in delivering the high performance database system that has
been under development for several years now.

Some of the many changes since the 4.10.2 release include:
MonetDB/XQuery 0.12.0 (nick-named "Ceres")
	Various improvments of functionality and performance.  Addition of
	XPath extensions for XML standoff annotations.  "Ceres" is a small
	detour on our trip to "Mars" [1], as update functionality is
	unfortunately still not robust enough for consumption by the
MonetDB/SQL 2.12.0
	Many bugfixes.  Support for local and global temporary tables.
	Preliminary support for triggers.

For a complete list of new features and known problems, please see the
release notes and errata list, available at:

MonetDB/Five Alpha Release 1

The efforts on the next generation of MonetDB, version Five, are
released now.  This snapshot of version Five of MonetDB is the very
first alpha release of this ongoing development.

Beware: alpha is alpha!

This software is only suitable as sneak-preview into the MonetDB
developers team's kitchen!  Come and taste some of the many delicious
spices we prepare.  Unlike the previous generation, Five comes with the
MAL language, instead of MIL, which makes it completely incompatible
with old MIL scripts.  However, the SQL sources work fine with this alpha
release.  Comparing the performance of both backends via SQL should give
you an indication of what our cooks will serve for dinner.

This first alpha "appetiser" release of MonetDB/Five is nick-named
"Tomato Soup".  Interested users are invited to visit our MonetDB/Five
page for more details:


The MonetDB family products are supported on i686, x86_64 and ia64 Linux,
i686 Solaris 10, ppc and ppc64 Mac OS X 10.4 and i686 Windows XP.
Binary distributions are available for Linux and Windows.

The new release is available for download from our SourceForge page:


Many man-hours were donated by various people to make this release
happening.  I want to thank al MonetDB developers for their efforts
spent into this piece of software.  All of our contributors and bug
reporters also deserve the credits for the time they put into their
