Upgrade notes for SimpleSAMLphp 1.18

The minimum PHP version required is now PHP 5.6.

Deprecations

• The use of the PHP memcache extension was deprecated in favour of memcached . In order to keep using memcache functionality you have to move to the PHP memcached extension, which is available from PECL; see https://pecl.php.net/package/memcached. The former is considered abandoned and it's safe use can no longer be guaranteed.

  There are a few options here: - Depending on your distribution, the package may just be available for you to install - You could use the package from the REMI repository if you're on RHEL; https://rpms.remirepo.net/ - Download the source from https://pecl.php.net/package/memcached and compile the source as a PHP-extension manually; https://www.php.net/manual/en/install.pecl.phpize.php

• Support for SAML1.1 / Shibboleth 1.3 will be discontinued in a future release.

• The class SimpleSAML\Auth\TimeLimitedToken is now deprecated and will be removed in a future release If your custom module relies on this class, be sure to make a copy into your repository and make sure to also copy the unit tests that come along.
• Setting privacypolicy in metadata files will be removed in a future release. It was only used by the consent module, which supports UIInfo 's PrivacyStatementURL . See https://simplesamlphp.org/docs/stable/simplesamlphp-metadata-extensions-ui on how to configure this.
