<h5>MessageFormat Changes</h5>
<p>MessageFormat and related classes (choice/plural/select) have been reimplemented,
with several improvements and some incompatible changes.
See the <a href="http://site.icu-project.org/download/48">ICU 4.8 download</a> page for details.</p>
<h5>Unknown system time zone - Etc/Unknown</h5>
The behavior of the time zone factory method TimeZone.getTimeZone(String) has changed in this release.
When an unknown time zone ID is specified in the method, previous versions return a TimeZone instance
with ID "GMT" (offset 0 and no daylight saving time). In ICU 4.8, the method uses "Etc/Unknown" as the
time zone ID (but still offset 0 and no daylight saving time) for the case. Existing software checking
the returned time zone ID to validate the input ID may need to be updated to support the new behavior.
