8.2rc1

!!! note "Multiple groups of instances and groups of users"

In temBoard 9.0, we plan to remove the ability to put an instance in several groups of instances
or a group of instances in several groups of users.

An instance will be attached to a single *Environment*
and each *Environment* will be administred by a single group of users.

temboard 8.2 warns you about instances and groups of instances matching these cases.
Read [GitHub issue #1283](https://github.com/dalibo/temboard/issues/1283) for details.
