+## 0.15.7
+ * Compensate for rare cases where a parsed Date in date-only format gets a
+ 1:00am time. This is presumably because of DST time-shifts. We may not be
+ able to correct these dates, because midnight may not exist at a transition
+ date, but we can cause the strict parsing to not fail for these dates.

## 0.15.6
* More upper case constant removal.

* Add missing support for specifying decimalDigits in compactSimpleCurrency.
* Fix doc comments for DateFormat (Pull request #156)
* Added a skip argument to not output the message in the extract step.
+ * Compensate for parsing a Date that happens at a DST transition, particularly
+ in Brazil, where the transition happens at midnight. This can result in a
+ time of 11:00pm the previous day, or of 1:00am the next day. Make sure that
+ the the 11:00pm case does not cause us to get the wrong date.
## 0.15.2
* Group the padding digits to the left of the number, if present. e.g. 00,001.
