So I went ahead and did the 3.4.2 WP update. Everything seems to work fine. There may be two small differences:
1: Seems to load faster. Can’t really tell, what with a shared server for the site. Server load is different at every moment. But it seems quicker.
2: Every so often I would load a page with 3.4.1 and the page would appear to load fully, but I would still get the rotating circle on the browser indicating that there was still something loading. Tried Y-Slow but could never see what it was. But, with 3.4.2 I have yet to get the rotating arrows. Maybe no connection, but still….
