There are also some changes to the templates. If you have any custom templates, they should be updated to match the ones included. Of notable changes is that the `t(...)`-functtes, they should be updated to match the ones included. Of notable changes is that the `t(...)`-function has been simplified, and takes far fewer parameters. It is backwardscompatible, but will write a warning to the log until updated. The backwards compatibility will be removed in a future version.

### New features

    custom authentication sources, authentication processing filters
    and themes.
  * An generic SQL autentication module added for those who store their

## Version 1.1

Released 2008-06-19. Revision 673.

When upgrading to version 1.1 from version 1.0, you should update the configuration files. Many options have been added, and some have moved or removed. The new configuration check page: `/simplesaml/admin/config.php` may be useful for determining what should be updated. Also note that the `language.available` option in `config.php` should be updated to reflect the new languages which have been added.

There are also several changes to the template files. If you have done any customizations to these, you should test them to make sure that they still work. Some changes, such as allowing the users to save the IdP choice they make in the discovery service, will not work without updating the templates.

New localizations in version 1.1: Sami, Svenska (swedish), Suomeksi (finnish), Nederlands, Luxembourgish, Slovenian, Hrvatski (Croatian), Magyar (Hungarian).
