sabre/xml 1.5.0 released

We just released sabre/xml 1.5.0. This release puts the minimum PHP version at PHP 5.5.

This release fixes an infinite loop bug during parsing of some invalid XML documents, and contains an improvement in how we're dealing with the "context stack", thanks to the PHP 5.5 finally keyword. Upgrading is recommended.

Upgrade sabre/xml by running:

composer update sabre/xml
