Version comment: I planed to make v. 3.57d last version of Tomcat and switch to development of ConceptA, but first version of ConceptA attract my attention to Tomcat's problem with head on targeters. And researching it i found 3 bug in Tomcat fixed in this version. I do not know already, but my current plan is release Tomcat's v. 3.58 with better head on performance and stop development. But who knows - this day shows, that each last version has ways to improvement:)
