Dear MonetDB users and developers (and those who want to become either or both ;-), we proudly announce the release of our new open-source XQuery processor "MonetDB/XQuery 0.8", which is based on the "Pathfinder" XQuery-to-Relational Algebra compiler and powered by "MonetDB 4.8". See the MonetDB/XQuery web site (http://monetdb-xquery.org/) for detailed product information and the Pathfinder web site (http://pathfinder-xquery.org) as well as the respective technical report (http://www.cwi.nl/htbin/ins1/publications?request=abstract&key=BoGrMaRiTe:TR-CWI:05) for scientific background information. All users are highly advised to use the releases as of now (see below for details concerning download and/or CVS checkout/update). Please note, though, that as of MonetDB 4.8 the database format has changed. Hence, MonetDB 4.8 does no longer work with (old) databases created with previous versions! To use the new version, you need to start with a new "virgin" database (i.e., empty "dbfarm" directory). In case your are upgrading from some older version, and want/need to keep/migrate your database(s), please contact us via the MonetDB-Users mailing list https://lists.sourceforge.net/lists/listinfo/monetdb-users (or via email to monet@cwi.nl). Detailed information about migrating old databases will soon be made available. To ask for support and report bugs or problems, please use the MonetDB-Users mailing list at SourceForge (https://lists.sourceforge.net/lists/listinfo/monetdb-users) or the bug tracing system at SourceForge (http://sourceforge.net/tracker/?group_id=56967&atid=482468); however, please always state clearly, which version of MonetDB you are using (as the Mserver tells you at startup)! Any support for the now obsolete "MonetDB 4.6" & "MonetDB/SQL 2.6" will stop as of now. You'll find an overview of the most important changes since MonetDB 4.6 & MonetDB/SQL 2.6 at http://monetdb.cwi.nl/Development/Roadmap/Version4.8/ . Download ======== Pre-packaged source- & binary-distributions are available on SourceForge: http://sourceforge.net/project/shownotes.php?release_id=305151 . CVS update ========== If you are already using a CVS version of MonetDB, sql, or pathfinder, you can run either "cvs update -dP -rMonetDB_4-8-0" (MonetDB) "cvs update -dP -rSQL_2-8-0" (sql) "cvs update -dP -rXQuery_0-8-0" (pathfinder) to get this very release, or "cvs update -dP -rMonetDB_4-8" (MonetDB) "cvs update -dP -rSQL_2-8" (sql) "cvs update -dP -rXQuery_0-8" (pathfinder) to get the most recent version in the release branch. The difference is, that via the first option, you are "stuck" with this very release, i.e., future "cvs update -dP" (without "-r..." or "-A") will not change your checked-out version; via the second option, however, future "cvs update -dP" will get you again the latest version in the release branch. CVS check-ins ============= All bug fixes (and only these!) on MonetDB, sql, and/or pathfinder are bound to go to the new release candidate branches ("MonetDB_4-8"/"SQL_2-8"/"XQuery_0-8"), only! On a regular basis, we will then take care of propagating these bug-fixes back to the respective development trunks. All new features are bound to go to the respective development trunks (and only there!). As usually, any (constructive;-)) comments and feedback are more than welcome! Enjoy!
