Mondrian 3.0 Milestone 1

Over the past few weeks, we’ve been working hard to get Mondrian 3.0 feature complete and relatively bug free. This is a major release, with large architectural and functional changes. I spent the last part of 2007 implementing the new shared dimensions architecture for Mondrian. This change cleaned up a lot of code in Mondrian, along with enabling new features like sharing the same dimension multiple times in a single cube, and also better management of shared dimensions within Virtual Cubes.

In January, I worked with Julian on squashing bugs. Earlier in the month we triaged all the bugs that have been logged since 2006. Now that we’ve assigned and prioritized them, tracking down bugs has been a great way for me to become more familiar with the Mondrian code base.

Some of the other major features that Julian has been working on this round include better role support, olap4j API support, and a much richer set of VBA and Excel function support.

Read about all the changes in the change log, and of course download this milestone release, kick the tires, and let us know what you think!
