I tried Kepler yesterday and encountered a couple of problem.

First, the Maven option "Download repository index updates on startup" is not checked by default, so dependency search doesn't work out-of-box.

Second, there seems to be some bug that prevents changing the version of the Dynamic Web Module project facet. This is a serious problem as the Maven webapp archetype creates webapps in Servlet Spec 2.3 and I want to change it to 3.0.

Kepler-SR1 will be released soon. I hope these problems will be fixed by then.
