[Plugin: WordPress.com Stats Helper] Still compatible

Currently running this plugin on a v2.8.4 blog and I haven’t come by any incompatibilities as of yet. If nothing is reported, maybe list this as 2.8.4 compatible so that newbies such as myself can breathe a little easier? ??

Also, is this plugin still actively developed or has development been abandoned?
