= 2.6.16 =

Fix: Remove user's role when removing them from the approved list. This is a security feature, in case a removed user is presumed deleted from the site. Since Authorizer does not delete users (to avoid the issue of reassigning or deleting that user’s content), removing their role removes all capabilities from the site until they are re-added to the approved list.

= 2.6.15 =

Fix for duplicate users in approved list (users added via authorizer_automatically_approve_login filter were re-added to approved list each time they logged in).

= 2.6.14 =

Props @6hogan for finding that!

= 2.6.11 =

Fix for CAS logins redirecting to the redirect_to param of wp-login.php.
Fix for redirect after CAS logout on some CAS servers requiring whitelisted services (add a trailing slash to the logout service param).

Allow multiple whitelisted domains under Google Hosted Domain. Props Michael K. for the suggestion!

Fix for immediate CAS redirect hook firing after content was sent to browser, triggering a PHP warning if output buffering isn't enabled on the web server. Props @steven1350 for reporting the bug!

= 2.6.9 =

Fix for blocked flag in usermeta not getting removed when unblocking a user.
Feature: Add filter to inspect CAS attributes and automatically approve a user based on any values there. Example:

 *   Whether to automatically approve the currently logging in user.
 * @param array $user_data User data returned from external service.
 */
function approve_all_faculty_logins( $automatically_approve_login, $user_data ) {
  // Automatically approve logins for all faculty members.
  if (
    isset( $user_data['cas_attributes']['eduPersonAffiliation'] ) &&
    'faculty' === $user_data['cas_attributes']['eduPersonAffiliation']
  ) {
    $automatically_approve_login = true;
  }
  return $automatically_approve_login;
}
add_filter( 'authorizer_automatically_approve_login', 'approve_all_faculty_logins', 10, 2 );

Fix for mixed line endings in phpCAS library, causing warnings when running PHP Compatibility Checker plugin. Props @wpgirl369/@eshannon3 for the pull request!
Fix: Never block access to super admins (or admins in single site mode). Props @eizzumdm and @nreljin!
Add user to network approved list when they are granted super admin privileges on the Edit User screen outside of Authorizer. Remove user from network approved list when this is revoked (and readd them to the approved list on any site they are currently a member of).
Fix for notification emails sent to all site users if plugin wasn't correctly activated.
Handle CAS servers that return an email address in response to phpCAS::getUser()

= 2.6.5 =

Use wp_remote_get() instead of curl to check CAS server availability. php-curl is no longer a dependency.
Fix for error introduced in last version with cacert.pem updating.

= 2.6.4 =

Use wp_safe_remote_get() instead of file_get_contents() to update cacert.pem. Props @kriswme2!
Fix error message shown when login form is first shown and LDAP is enabled. Props @akompanas!
Fix for lengthy timeout if ldap_start_tls() fails when connecting to an LDAP server. Props @TJuberg!
Fix a bug preventing first-time login of an approved user when a WordPress user already existed with the same username (but a different email address).
Remove the spinner overlay when logging in via Google (user could accidentally close the Google sign-in popup, and the spinner prevented them from reopening it by clicking on the "Sign In with Google" button).
Clean up plugin files (rename 'inc' directory to 'vendor').
Fix for CAS version option being selectable when it's been multisite overridden.
Fix for missing translatable string (anonymous access message in bootstrap dismissible alert).
Show all roles in all sites on the Approved Users role dropdown in network admin.

Feature: Sync role and email address in approved list when changed elsewhere.
Feature: Add super admins to network approved list on plugin activation.

Fix for whitespace and "mailto:" in emails (trim when clicking approve button).
Fix for external=wordpress safety login not working if option to immediately redirect to CAS is enabled.
Fix for deprecation warning in WordPress 4.6: wp_get_sites().
Fix for deprecation warning in WordPress 4.6: wp_new_user_notification().
Fix for multisite users not being removed from pending lists.
Improve code efficiency.

= 2.6.2 =

Revert LDAP/CAS email domain guessing logic (some existing users rely on the old method to determine email address domains). If email domain or CAS/LDAP attribute containing email address is not specified in Authorizer options, guess that email domain is the last two components of the CAS/LDAP host when splitting by periods (e.g., authn.example.com would return an email domain of example.com).

= 2.6.1 =

Tested up to WordPress 4.6.1.
Update cacert.pem file.

= 2.6.0 =

Tested up to WordPress 4.6.
Feature: Add method for constructing email address for CAS/LDAP servers that don't return an email attribute. Simply enter @yourdomain.edu into the mail attribute field to have email addresses be constructed as username@yourdomain.edu.
Fix: Updates to cacerts.pem for CAS servers now works for WordPress installs behind a proxy. Props dchambel! #13
Feature: Allow restricting Google logins to a single Google Apps hosted domain (e.g., mycollege.edu).
Update google-api-php-client from 1.0.5-beta to 1.1.5.
Fix for REST API integration: Authorizer will now deny read/view access via the REST API if the site is private and the user is not authenticated. Other REST API access is unaffected by Authorizer, and is managed by the REST API authentication schema (cookie, oauth, or basic authentication). See http://v2.wp-api.org/guide/authentication/ for details.
Fix: Warn if php_openssl.dll is not installed on Windows servers (cannot update cacert.pem if it's missing).
Fix for mcrypt key length error in php 5.6 and higher.
Fix for broken newlines in notification emails (also update translations).
Feature: Customize user roles based on CAS or LDAP attributes. Example:

/**
 * Filter the default role of the currently logging in user based on any of
 * their user attributes.
 *
 * @param string $default_role Default role of the currently logging in user.
 * @param array $user_data     User data returned from external service.
 */
function my_authorizer_custom_role( $default_role, $user_data ) {
  // Allow library guests to log in via CAS, but only grant them 'subscriber' role.
  if (
    isset( $user_data['cas_attributes']['eduPersonPrimaryAffiliation'] ) &&
    'library-walk-in' === $user_data['cas_attributes']['eduPersonPrimaryAffiliation']
  ) {
    $default_role = 'subscriber';
  }
  return $default_role;
}
add_filter( 'authorizer_custom_role', 'my_authorizer_custom_role', 10, 2 );

= 2.5.1 =

Updated Spanish translations. Props @elarequi.
Fix: Include translatable strings found in javascript files.
Fix: Force lowercase emails from LDAP. Props @akompanas.
Fix: Set some LDAP defaults likely to be the same on all installs: ldap_port, ldap_attr_username.
Fix: Construct LDAP default email domain from LDAP search base, not from host (helps to differentiate between subdomain installs and domains with country codes).

= 2.5.0 =

Translations: Props to @elarequi for wrapping text strings in the translation functions and for providing Spanish translations.
- Fichero authorizer.php: Se preparan todas las cadenas necesarias, para hacerlas traducibles.
- Se crea el directorio /languages, con los ficheros de traducción.
Translations: Props @jojaba for providing French translations.
Feature: Allow 404 pages to be shown publicly on restricted sites.
Feature: Add filter to inspect CAS attributes and deny access based on any values there. Props @jojaba for the suggestion. Example:

/**
 * Filter whether to block the currently logging in user based on any of their
 * user attributes.
 *
 * @param bool  $allow_login Whether to block the currently logging in user.
 * @param array $user_data   User data returned from external service.
 */
function check_cas_attributes( $allow_login, $user_data ) {
  // Block access to CAS logins from library guests.
  if (
    isset( $user_data['cas_attributes']['eduPersonPrimaryAffiliation'] ) &&
    'library-walk-in' === $user_data['cas_attributes']['eduPersonPrimaryAffiliation']
  ) {
    $allow_login = false;
  }
  return $allow_login;
}
add_filter( 'authorizer_allow_login', 'check_cas_attributes', 10, 2 );

Feature: Add action for inspecting attributes returned from CAS.
Fix: Users deleted in WordPress will be removed from Authorizer lists. Props @jojaba for catching that.

Cleaned up code complexity. Props @mackensen for the pull requests.
