[jboss-dev] subversion 1.5 diffs

So I'm reading through the current svn manual merging section, and it says: "In the examples that follow, we're assuming that both your Subversion client and server are running Subversion 1.5 (or later). If either client or server is older than version 1.5, things are more complicated: the system won't track changes automatically, and you'll have to use painful manual methods to achieve similar results. That is, you'll always need to use the detailed merge syntax to specify specific ranges of revisions to replicate (see the sec- tion called “Merge Syntax: Full Disclosure” later in this chapter), and take special care to keep track of what's already been merged and what hasn't. For this reason, we strongly re- commend that you make sure your client and server are at least at version 1.5. " Of course we are running 1.4.2. It looks like the big change was tracking merge information via an svn:mergeinfo property?
