2.8.6 (Build: 2017012500)

Resolved bug where old (overwritten) Moodle Assignment rubric selections display in the report, alongside the latest rubric selections.
Updated language files to highlight that the archiving features are not suitable for production Moodle instances, due to issues with checking permissions on older versions of Moodle.
The workaround is to install the My feedback plugin on every Moodle instance independently.
