 Installation instructions for HAProxy
 =====================================
 
-HAProxy 2.0 is a long-term supported stable version, which means that it will
-get fixes for bugs as they are discovered during several years and will not
-receive new features. Versions which include the suffix "-dev" are development
-versions and should be avoided in production. If you are not used to build from
-sources or if you are not used to follow updates then it is recommended that
-instead you use the packages provided by your software vendor or Linux
-distribution. Most of them are taking this task seriously and are doing a good
-job at backporting important fixes. If for any reason you'd prefer a different
-version than the one packaged for your system, you want to be certain to have
-all the fixes or to get some commercial support, other choices are available
-at http://www.haproxy.com/.
