-    <h3>C++ BasicTimeZone subclassing-API breaking changes</h3>
-    <p>We have made make some changes to the C++ BasicTimeZone(basictz.h) for ICU 51
-    that will make it easier to use some time zone support features found in BasicTimeZone
-    (basictz.h), but the changes are incompatible for subclasses. If there are subclasses,
-    they will have to be modified as well.</p>
-
-    <p>BasicTimeZone is a subclass of TimeZone and providing some enhanced features, such as
-    getNextTransition and getPreviousTransition. The class is used as the base class of all
-    of ICU's time zone implementation classes. User Classes directly extending TimeZone and
-    consumers of ICU TimeZone implementation classes are not affected by the changes.</p>
-
-    <p>For details see the email "ICU4C C++ BasicTimeZone subclassing-API breaking changes"
-    sent on 2013-Feb-5 to the icu-support
-    <a href="http://site.icu-project.org/contacts">mailing lists</a>,
-    and <a href="http://bugs.icu-project.org/trac/ticket/9648">ICU ticket #9648</a>.</p>

-    <h3>Date format pattern "V"</h3>
-    <p>The date format pattern "V" was introduced in ICU 3.8 (inherited from CLDR 1.5) as
-    a variation of pattern "z" to support time zone abbreviation format such as "PST".
-    The pattern "z" prints out a time zone abbreviation only when it is commonly used for a locale.
-    The pattern "V" was slightly different from pattern "z" and the pattern designates
-    a time zone abbreviation even it is not commonly used for a locale. For example, time
-    zone abbreviation "AEST" for Australian Eastern Standard Time might not be well recognized
-    by people in the United States. For the zone, pattern "z" does not use "AEST" (instead, use
-    UTC offset format "GMT+10:00", as the fallback) , while pattern "V" used to print out "AEST".
-    In CLDR 21, the data used for checking commonly used or not was completely removed (CLDR
-    ticket <a href="http://unicode.org/cldr/trac/ticket/4052">#4052</a>), so the difference
-    between pattern "z" and "V" is no longer available since ICU 49 (based on CLDR 21 specification).</p>
-
-    <p>In CLDR 23, the CLDR technical committee decided to reuse the semantically deprecated
-    pattern "V" for a different purpose. With the new specification, the date format pattern
-    "V" is used for short time zone IDs, such as "uslax" for zone America/Los_Angeles. ICU 51
-    implements the new specification. So existing ICU users currently using custom date format
-    patterns with pattern "V" are suggested to change them to pattern "z".</p>
-
-   <p>Note that the existing pattern "VVVV" for a time zone's generic location name is not
-   affected by the new specification and the pattern "VVVV" continues to work as same as
-   previous ICU releases.</p>
