Installation instructions for HAProxy
=====================================
-This is a development version, so it is expected to break from time to time,
-to add and remove features without prior notification and it should not be used
-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 to use 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/.
+HAProxy 2.2 is a long-term supported version, which means that it will get
+fixes for bugs as they are discovered till around Q2 2025 and will not receive
+new features. This version is suitable for general deployment as it is expected
+to receive less frequent updates than regular stable branches which have an odd
+digit in the minor version number. New users are strongly advised encouraged to
+use only such long-term supported versions such as the ones provided by their
+software vendor or Linux distribution. If for any reason you would 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/.
