title: How to find out Subversion repository version?
body: <p>How can I determine current version of my repository to see if I need to upgrade it (svnadmin upgrade)?</p>
  
  <p>In reality I'm hosting SVN with 3rd party and I want to find out if I need to ask them to upgrade my repos or not.</p>
  
  <p>I'm asking since 1.5 server will keep repo version at 1.4, unless I miss something?</p>
