This was my same feeling :-) and so I went for the trunk to have things working quickly, but I also have to consider which one is the best version since I am going to deploy it in the near future in an enterprise environment and choosing the best version is an importat step. I am quite new to Solr but I agree with Alessandro that probably using a slightly patched release should theoretically be more stable than the trunk which get many updates weekly (and daily). Cheers, Tommaso
