I agree with this assessment. It is currently very easy to backport almost all new functionality from trunk (5x) to the 4x branch. Although there are some features unique to trunk, I don't think the list is extensive yet. I thought that the switch to Java 7 in trunk would force a relatively short time line to 5.0, but the Java 7 requirement itself was backported to 4x, so that influence is no longer there. > I'll offer a prediction: 5.0 will happen when the Lucene guys at > Elasticsearch come up with some great new ideas for how to leapfrog Solr! > (And then we watch how the Heliosearch guys respond to that!) I still think that a serious push for 5.0 will not begin until backporting small and medium sized code changes from trunk to 4x requires significant manual intervention. If the leapfrog situation happens as you describe, and the resulting Solr changes can easily be backported to 4x, then I don't think it will spur a new major release.
