+- Breaking change: the versioning function is not quoting and escaping the name of the history table. Any name that needs quoting (upper case, special chars) should be provided as parameters already quoted and escaped.

 # 0.3.0 - 2020/7/14
 
 - Add parameter to ignore updates without actual changes

+A note on the history table name. Previous versions of this extension quoted and escaped it before usage.
+Starting version 0.4.0 we are not escaping it anymore and users need to provide the escaped version as a parameter to the trigger.
+
+This is consistent with the c version, simplifies the extension code and fixes an issue with upper case names that weren't properly supported.
