2-----------------------
3This is a list of the most important changes in 2.x versions. It is by
4no means complete, listing only user-visible changes which are interesting.
5The ultimate way to know what has changed is to run diff, or even neater,
6ask CVS about it:
7
8  * Checkout the archive (see doc/cvs for how you can do this)
9  * Determine which tags are valid, by running this command from the
10    project root directory:
11      cvs status -v -l Makefile
12    Valid tags are usually like form V2-1-0 for version 2.1.0
13  * Ask cvs for the difference between two versions:
14      cvs diff -r TAG1 -r TAG2 DIFF-OPTIONS
15    for example:
16      cvs diff -r V2-0-0 -r V2-0-1 -u
