-## Release History
-
-  - `1.3.0`
-
-  Allow a leading `+` sign in the year component [#11](https://github.com/relvacode/iso8601/issues/11)
-  - `1.2.0` 
-  
-  Time range validity checking equivalent to the standard library.
-  Note that previous versions would not validate that a given date string was in the expected range. Additionally, this version no longer accepts `0000-00-00T00:00:00` as a valid input which can be the zero time representation in other languages nor does it support leap seconds (such that the seconds field is `60`) as is the case in the [standard library](https://github.com/golang/go/issues/15247)
-  - `1.1.0` 
-  
-  Check for `-0` time zone
