These release notes are replicated for historical purposes only. The release is not supported anymore.
Important consideration when upgrading to this release.
- In this release we have fixed bug 3474Z. This bug made it possible that there were duplicates despite there being a unique or primary key constraint present. This could only happen for multi-column constraints. MonetDB maintains an internal column containing a hash for multi-column constraints, and there was a bug in the maintenance code of this column. During an upgrade, this column needs to be recreated. This is done by dropping and adding back the constraints. If there are no duplicates, adding back the constrains should work without problem, but if there are duplicates, adding the constraints will fail. There is unfortunately no easy way to tell the user, so after having made the first connection to the server (when the upgrade happens), check the merovingian log (if you use merovingian -- also known as monetdbd) or the server output window (if you don't use merovingian).
Jaql support is removed.
- The experimental code for Jaql support has been removed. If you have RPM or DEB packages for Jaql installed from an earlier version (MonetDB-jaql and monetdb5_jaql respectively), you will need to uninstall them before the upgrade.
Upgrade code fixed.
- The code to upgrade from previous releases still had some bugs. These have now been fixed. Upgrades directly from the Feb2013 release should work again. Also, upgrading to this version should fix some problems that were caused by the upgrade to the Oct2014 release.
Oct 2014-SP4 bugfix release
- Due to a code conflict it is not possible to upgrade to this bug fix release from a release older than the Oct2014 release. If you are running an older release, first upgrade to the Oct2014 release, and then to Oct2014-SP4.

Oct 2014-SP2 bugfix release
- Changes to the Perl interface, thanks to Stefan O'Rear:
- removes "use sigtrap", because this has global effects and should not be used by modules, only by the application.
- allows Perl 5.8.1+ Unicode strings to be passed to quote() and included in statements (UTF-8 encoded, as expected by Monet's str module)
- quote and unquote now use the same quoting rules as the MonetDB server, allowing for all characters except NUL to be round-tripped
- several character loops have been reimplemented in regex for much greater performance
- micro-optimizations to the result fetch loop
- block boundaries are preserved in piggyback data so that Xclose is not appended or prepended to a SQL command
- diagnostic messages #foo before a result header are ignored, this is necessary to use recycler_pipe
- fail quickly and loudly if we receive a continuation prompt (or any other response that starts with a non-ASCII character)
- header lines must start with %, not merely contain %, fixing a bug when querying a table where string values contain %
- after closing a large resultset, account for the fact that a reply will come and do not lose sync
- allow a MAPI_TRACE environment variable to dump wire protocol frames to standard output
- fixes maximum MAPI block size to match the server limit of 16k. previously would crash on blocks larger than 16k
- Fixed a typo in a column name of the sys.tablestoragemodel view (auxillary changed to auxiliary).
- 3467: Field aliases with '#' character excise field names in result set.
- 3605: relational query without result
- 3619: Missing dll on MonetDB Start
- 3622: Type resolution error
- 3624: insert of incomplete or invalid ip address values in inet column is silently accepted but the values are not stored (they become/show nil)
- 3626: casting a type without alias results in program contains errors
- 3628: mclient and ODBC driver report 'type mismatch' when stddev_pop used in a select which returns 0 rows
- 3629: IF THEN ELSEIF always evaluates the first test as true
- 3630: segv on rel_order_by_column_exp
- 3632: running make clean twice gives an error in clients/ruby/adapter
- 3633: Wrong result for HAVING with floating-point constant
- 3640: Missing implementation of scalar function: sql_sub(, )
- 3641: SQL lexer fails to detect string end if it the last character is U+FEFF ZERO WIDTH NO-BREAK SPACE
- 3642: Combined WHERE conditions less-than plus equals-to produce incorrect results
- 3643: Missing implementations of scalar function: sql_sub(, arg2)
- 3644: COPY INTO fails to import "inet" data type when value has prefix length in CIDR notation
- 3646: ORDER BY clause does not produce proper results on 'inet' datatype
- 3649: recycler crashes with concurrent transactions
Oct 2014 SP1 bugfix release
- Fixed adding of 0 intervals to dates.
- The libraries included in the Windows installers have been upgraded. We now use libxml2-2.9.2, openssl-1.0.1j, pcre-8.36, and zlib-1.2.8.
- Implemented a change to the way in which string bats are appended. We now try harder to limit the growth of the string heap.
- Fixed some problems with BATsample. It was possible for BATsample to return a value that was just beyond the end of the sampled BAT. Also, on some systems the range of the rand() function is rather limited (0..32767) and trying to get a sample larger than this range would result in an infinite loop.
- Fixed sys.queue() implementation to report on other queries being executed.
- A number of bugs were fixed in the code to upgrade a database from previous releases. This version should fix the upgrade of a database that had been upgraded to the Oct2014 release, but also properly upgrade directly from Jan2014 and Feb2013 releases.
- 3580: cosmetic change (append newline)
- 3609: Incorrect use of generate_series
- 3611: quantile() and median() commands crash when used 2x on the same variable on a null table
- 3612: assertion failure when deleting rows from table to which a FK constraint is defined
- 3620: ORDER BY broken when using UNION ALL
- 3621: Hexadecimal literal vs decimal literal
Known issue when upgrading old versions.
Oct 2014 feature release
- Removed algebra.materialize.
- Removed algebra.kunique and algebra.tunique. They were subsumed by algebra.subunique.
- Remove algebra.antiuselect and algebra.thetauselect. They were subsumed by algebra.subselect.
- Removed algebra.topN and its imlementation BATtopN. The function was not used.
- Removed aggr.histogram and its implementation BAThistogram. The function was not used, and did not produce output in the "headless" (i.e. dense-headed) format. Histograms can be created as a by-product of group.subgroup.
- Jacqueline, the MonetDB/JAQL frontend, has been removed. The frontend never grew beyond being experimental, and there is no interest anymore to maintain the code.
- monetdb create: add -p flag to set monetdb user password on creation, and therefore allow creating the database in unlocked state
- Changed mapi_timeout argument from seconds to milliseconds.
- Changed mnstr_settimeout function so that the specified timeout is now in milliseconds (used to be seconds), and that it also needs an extra argument specifying a callback function (no arguments, int result) that should return TRUE if the timeout should cause the function to abort or continue what it was doing.
- Added "multifarm" capability. It is now possible to separate persistent and transient BATs into different directories (presumably on different disks). This can be done by using the --dbextra option of mserver5 (see the man page).
- Added PostgreSQL compatible string TRIM, LTRIM, RTRIM, LPAD and RPAD functions
- Stop support for upgrading directly from a database created with a server from the Oct2012 release or older. You can upgrade via the Feb2013 or Jan2014 release.
