## 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.
There are two new functions in security.inc: checkIfWriteAccessIsAllowed() and checkIfPasswordChangeIsAllowed()
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"

### baseModule

The class variable $base is no longer visible in child classes. Please use $this->getAccountContainer() to access the accountContainer object.
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.
- listPrintAdditionalOptions(): If you want to display additional conrols for a list please use this function. The controls will be placed under the account table.

- getRequiredExtensions: Allows to define required PHP extensions

- getLDAPAliases: list of LDAP alias names which are replaced by LAM

The class variable "triggered_messages" in baseModule was removed.
