<p>
-See the <a href="http://www.icu-project.org/download/latest_milestone.html">ICU 4.4 milestone download page</a> about
+The new system time zone data format supporting 64bit transition time data
+implemented in ICU4J 4.4 introduced a serialization incompatibility issue
+in the internal TimeZone implementation class (e.g. An instance of TimeZone
+created by <code>TimeZone.getTimeZone(String)</code> with an Olson tzid, such as
+<code>"America/Los_Angeles"</code>).
+
+The new implementation reads only the system time zone identifier string
+when object data was serialized by ICU4J 4.2 or older versions. Also, ICU4J
+4.2 or older versions cannot read object data created by ICU4J 4.4.
+
+The system time zone implementation class may be used by other ICU4J
+public API classes, such as <code>Calendar</code> and <code>DateFormat</code>,
+therefore, these classes are also affected.
