+= 2.0.0 [2009-04-12]
+- Error value formats are now specified in the i18n locale file instead of updating plugin hash. See OTHER CUSTOMISATION section in README.
+- Date/time select helper extension is disabled by default. To enable see DISPLAY INVALID VALUES IN DATE HELPERS section in README to enable.
+- Added :format option to limit validation to a single format if desired
+- Matcher now supports :equal_to option
+- Formats.parse can take :include_offset option to include offset value from string in seconds, if string contains an offset. Offset not used in rest of plugin yet.
+- Refactored to remove as much plugin code from ActiveRecord as possible.
+
+= 1.1.7 [2009-03-26]
+- Minor change to multiparameter attributes which I had not properly implemented for chaining
+
+= 1.1.6 [2009-03-19]
+- Rail 2.3 support
+- Added :with_date and :with_time options. They allow an attribute to be combined with another attribute or value to make a datetime value for validation against the temporal restrictions
+- Added :equal_to option
+- Option key validation
+- Better behaviour with other plugins using alias_method_chain on read_attribute and define_attribute_methods
+- Added option to enable datetime_select extension for future use to optionally enable. Enabled by default until version 2.
+- Added :ignore_usec option for datetime restrictions to be compared without microsecond
+- some refactoring
+
+= 1.1.5 [2009-01-21]
+- Fixed regex for 'yy' format token which wasn't greedy enough for date formats ending with year when a datetime string parsed as date with a 4 digit year
+
+= 1.1.4 [2009-01-13]
+- Make months names respect i18n in Formats
+
+= 1.1.3 [2009-01-13]
+- Fixed bug where time and date attributes still being parsed on read using Rails default parser [reported by Brad (pvjq)]
+
 = 1.1.2 [2009-01-12]
 - Fixed bugs
  - matcher failing for custom error message without interpolation keys using I18n

+* String value
+* Date, Time, or DateTime object value
+* Proc or lambda object which may take an optional parameter being the record object

 the same type as the validation method type. So using validates_date means all
-values are compared as dates.
