To notify you, the users of this service, about changes and updates, a tiny little pulsating red dot will be shown down in the footer at the link to this blog. Every time there is an update, a blog post will explain what happened, what changes, what's new, what's fixed, etc. Many questions people have are already answered in these posts, so I think it's important to keep an eye on the blog. The red dot will disappear after opening the latest blog post.
This little update was implemented now, to bring under your attention the last two updates: version 5.0 and version 5.1.0.
Enjoy!
