Yesterday I uploaded Hotspots RC1 to the download section (dev area). This is supposed to be the last version before a stable release. Of course if any major problems are found I reserve myself the right to release RC2 :)
This version fixes all reported problems since beta2 + ads a new content plugin that you can use to show a specific hotspot in your articles.
You can find more information on what is new in version 3 by looking at this blog post.
In the next 7 days Petar and Yves are going to provide support for Hotspots so please don't be too harsh on them!
Don't use on production sites! You've been warned! :)
