This is a list of API changes for all LAM releases.
2.5.0 -> 2.6.0
The class 
baseType has two new member variables:
  - $LABEL_CREATE_ANOTHER_ACCOUNT
- $LABEL_BACK_TO_ACCOUNT_LIST
They can be used to show a more specific text when the user is asked to
create another account or return back to the account list.
The meta HTML code now supports image buttons.
2.4.0 -> 2.5.0
Self service
$selfServiceSettings in class 
baseModule is now an object of the class 
selfServiceProfile. This way all profile settings can be read. To access the module settings use 
$this->selfServiceSettings->moduleSettings.
