## 2.2.0 -> 2.3.0

### Style changes

If you have defined your own account types then you need to update your CSS files (style/type_<type>.css).
Please change "table.<type>list input,select" to "table.<type>list input,select,button" and "fieldset.<type>edit input" to "fieldset.<type>edit input,select,button". "fieldset.<type>edit select" may be deleted afterwards.

Account lists now support to define tools. These are displayed as linked images like the edit and delete links in the list.
Overwrite lamList::getAdditionalTools() to use this feature.

All options are now saved in cookies for one year.

### Base module

The baseModule class has a new protected option: $autoAddObjectClasses You can set it to false if you do not want that your module's object classes are added when creating or loading an account.

### Constructors

LAM now uses the PHP5 syntax for constructors: __construct()

Each server profile now defines an access level.
Currently these are:

- write access
- password changes
- read access

Please check your code and prohibit any actions which do not fit the current access level.

Only LAM Pro allows to change the access level from write access to a smaller level.

## 2.0.0 -> 2.1.0

### Style changes

- "table.<type>list input" changed to "table.<type>list input,select"

Several other class variables in accountContainer etc. are now private. Use the new access methods.

## 1.3.0 -> 2.0.0

LAM is now PHP5 only. Several variables are now private and need to be accessed via functions.

## 1.2.0 -> 1.3.0

### New lamList functions

- listPrintTableCellContent(): This function allows you to control how the LDAP attributes are displayed in the table. This can be used to display links or binary data.

### New module functions

- getRequiredExtensions: Allows to define required PHP extensions
- getManagedObjectClasses: Definition of managed object classes for this module
- getLDAPAliases: list of LDAP alias names which are replaced by LAM
- getManagedAttributes: list of LDAP attributes which are managed by this module

The LDAP attributes are no longer loaded by reading the LDAP schema. If your module does not implement the load_attributes() function then you have to use getManagedAttributes() or the meta data to specify them.
The class variable "triggered_messages" in baseModule was removed.
