+This is a list of the most important changes between 2.x versions. It is by
+no means complete, listing only user-visible changes which are interesting.
+The ultimate way to know what has changed is to run diff, or even neater,
+ask CVS about it:
+
+  * Checkout the archive (see doc/cvs for how you can do this)
+  * Determine which tags are valid, by running this command from the
+    project root directory:
+      cvs status -v -l Makefile
+    Valid tags are usually like form V-2-1-0 for version 2.1.0
+  * Ask cvs for the difference between two versions:
+      cvs diff -r TAG1 -r TAG2 DIFF-OPTIONS
+    for example:
+      cvs diff -r V2-0-0 -r V2-0-1 -u
+
+
