ec2-plugin cannot add specified instance tags on launched spot instances

It is really urgent for me to choose the latest EC2 plugin (still not released) in testing. It seems that there are no latest commits since two months ago.
I have configured the tags for my new spot instance request, like:
Name: Name
Value: Henry

But after the spot instance launched, it seems no tags have been attached to this spot instance.

Could you please fix it before the official release?

Thanks
Henry
