Release notes
*Sourced from [phpoffice/phpspreadsheet's releases](https://github.com/PHPOffice/PhpSpreadsheet/releases).*
> ## 1.8.0
> ### Security Fix (CVE-2019-12331)
>
> - Detect double-encoded xml in the Security scanner, and reject as suspicious.
> - This change also broadens the scope of the `libxml_disable_entity_loader` setting when reading XML-based formats, so that it is enabled while the xml is being parsed and not simply while it is loaded.
> On some versions of PHP, this can cause problems because it is not thread-safe, and can affect other PHP scripts running on the same server. This flag is set to true when instantiating a loader, and back to its original setting when the Reader is no longer in scope, or manually unset.
> - Provide a check to identify whether libxml_disable_entity_loader is thread-safe or not.
>
> `XmlScanner::threadSafeLibxmlDisableEntityLoaderAvailability()`
> - Provide an option to disable the libxml_disable_entity_loader call through settings. This is not recommended as it reduces the security of the XML-based readers, and should only be used if you understand the consequences and have no other choice.
>
