There are breaking changes in 8.1 to the ArrayAccess interface. The changes adapt to the new typed interface.Various style fixes and an updated composer file. Since older php version will not be compatible, I am cutting any references in the travis file as well.
Edit: Found a more elegant solution by just annotating the ArrayAccess methods with
#[\ReturnTypeWillChange]
. This way everything stays backwards compatible and it works with php 8.1 as well.
