Does this support APISIX 2.8?

Dashboard 2.8 can work with APISIX 2.8 and APISIX 2.9, but at the same time users can find that there are some function missing in UI, it will take some time to add , see here: https://github.com/apache/apisix-dashboard/milestone/17, after Dashboard 2.8 published, detailed 2.9 plan will also be announced.
