It gives me great pleasure to announce the release of STACK v4.2.
STACK 4.2 contains a number of significant, if minor, improvements. Many of these are basically internal, e.g we now have a version number attached to STACK questions, enabling questions to be shared and upgrades to issue warnings. There are significant improvements to the bulk testing, returning errors and identifying all questions without tests or worked solutions.
We have added in native multi-language support, to separate out languages in the question text.
We have add support for using JSXGraph (http://jsxgraph.org) for better support of interactive graphics, and as part of an input type.
We now have printed publicity materials for STACK
If anyone would like hard-copies please drop me an email to C.J.Sangwin@ed.ac.uk with your postal address and I'll be happy to mail you some.
Thank you for your continued interest in STACK, comments, contributions and collaborations welcome.
