A significant new release of Jd is now available. Old free, non-commercial keys are not valid with this release. If you have an old, free key and want to continue to use your current Jd version, you should backup your current version now in case it is inadvertently updated.
New ref /left option sets the data necessary for left-outer and inner joins. These new joins are in addition to the previous left1 join. The left1 join satisfied many requirements, but left-outer and inner make for a more complete set of functionality. New tutorial quandl_ibm shows how to easily load financial data from quandl. See the jdwiki release notes for more info. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
