+  <title>MongoDB PHP Driver 1.4.0</title>
+  <para>
+   The 1.4 series introduced fundemental changes in how connections are created to the MongoDB servers.

+   The most important improvements however deal with the handling of replica sets, 
+   especially nodes that timeout and nodes that are unreachable for various 
+   reasons. Besides the improvements to replica set handling, this release 
+   addresses issues with read preferences through mongos nodes. It also 
+   adds support for SSL enabled connections as well as journal and fsync 
+   connection string options.
