At the QA team we are going to organize Testing Days to cover new features for Jaunty.
It has happened before that a new feature well documented with its blueprint and its spec never gets tested and it happens to have a major bug that it is only found very late in the cycle.
We are trying to minimize these cases organizing special Testing Days to cover such features. So, if you’re developing a new feature and want it to be tested in a Testing Day, please, add the feature to the list in the wiki, so we can schedule it.
We will soon announce the next Testing Day and instructions on how to participate in helping to make Ubuntu better.
