So I guess it is time to call it stable :-) What is new? The most important change is that it is now possible to keep relations when an object is moved. This was a bit difficult before, but two new methods has been added to solve this. It is easier to create web forms to make relations. Also the documentation has been expanded a bit. What does it do? It solves a few common problems with Zope's object oriented database. Normally in a relational database some tables will be used to show relations between rows. It can be both "one to many", and "many to many". In Zope, doing the same thing is more difficult than it has to be. mxmRelations solves this problem in a rather simple way. enjoy! Max M
