Buoy, a complement to Pharo reached it's v6.0.0 version.
Pharo 6.1 is no longer supported
ExclusiveLogicalOr and StandardComparator are no longer present. Replace them by using self equalityChecker and self equalityHashCombinator properly configured. For more information, check the updated documentation. The Buoy-Deprecated package is available to manually load and provides rewrite rules easing the migration.
Namespace binding methods now check that the name to bind is a Symbol to help with some portability issues.
Some test cases were updated to use testing extensions not available on Pharo 6.1
