+- 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

+The temporal restrictions, with_date and with_time can take 4 different value types:
+* String value
+* Date, Time, or DateTime object value
+* Proc or lambda object which may take an optional parameter being the record object
+* A symbol matching the method name in the model
 
 When an attribute value is compared to temporal restrictions, they are compared as 
 the same type as the validation method type. So using validates_date means all
-values are compared as dates.
+values are compared as dates. This is except in the case of with_time and with_date
+options which effectively force the value to validated as a datetime against the
