- To provide a simpler installation, all files will go under the web
dir, and there's no longer need to create a symlink. Have
this in mind when upgrading, replacing the symlink you currently have
with the files from this release.

- Some of the new features need new configuration directives. To
upgrade, use the older config.php file, and only after a successful
upgrade you can take a look at config.default.php and fill out the new
directives into the config.php file

NEW REQUIREMENTS:

- Minimal supported PHP version is 5.2.4
- For YubiKey support php-curl package is required

# Description
Community-ID is an OpenID implementation in PHP which is OpenID 2.0 compliant.
* Community-ID is build to 100% on Open Source software and is release under the BSD license.
* Users can keep track of their trusted sites and manage them.
* For Community-ID administrators statistics are available to track registration of new users, authorized users per day or the number of trusted sites.
* Administrators can set the site in maintenance mode or send emails to all registered users.
* For user data and authentication, admin can choose the default db storage, or to connect to an LDAP server
