# Upgrade notes for SimpleSAMLphp 1.16

The default signature algorithm is now SHA-256 (SHA-1 has been considered
obsolete since 2014). For entities that need it, you can switch back to
SHA-1 by setting the `signature.algorithm` option in the remote entity
metadata.

In the Consent module, the `noconsentattributes` has been renamed to
`attributes.exclude`. The old name continues to work but is considered
deprecated.

The class `SimpleSAML_Error_BadUserInnput` has been renamed to
`SimpleSAML_Error_BadUserInput`.

The `authmyspace` module has been removed since the service is no longer
available.

The `casserver` module has been removed because it was an outdated version,
the up to date module is maintained in the
[simplesamlphp-module-casserver](https://github.com/simplesamlphp/simplesamlphp-module-casserver)
repository. It can be installed with composer:

```bash
composer require simplesamlphp/simplesamlphp-module-casserver
```
