Breaking API changes from 1.11 to 1.12 (no replies)

Hi,
As written here, there are several breaking changes in Piwik API between versions 1.11 and 1.12.
But I have noticed some which are not listed in the blog post:
- UserCountryMap widget no longer accepts 'columns[]' parameter and shows something like 'There is no data for this report' if this parameter is given
- module=API&method=CustomVariables.getCustomVariables&label={variable_name}&expanded=1 response does not contain a 'subtable' entry anymore (which used to contain values of the given custom variable)
