That sounds along where I was thinking myself. My feeling in terms of numbering is that for the most part once a minor (1.5, 1.6) release is pushed out (ie. 1.5.0 released as such) we should be very cautious about any new or changed features in the release. While deciding *which* features end up in a particular release, I think the release schedule should be "organic" unlike it seems major companies who really like to make major changes on a regular schedule. Thank you for the clarification.
