' . 'Hey there!' . '

' . '

' . 'Just wanted to say a big thank you to all of you out there for trying out our plugin in its early versions. We struggle hard to keep it solid and reach a full stable version! You have probably noticed, or will notice in a just about a minute, that a number of enhancements and user interface improvements have been added in this version (0.7.0). The reason the last versions came up so close to one another was that, well honestly, it was August and we finally had some extra spare time!' . '

' . '

' . 'As we are reaching version 1.0, the plugin features are becoming more and more stable and, we believe, more and more powerful. One of the most interesting, yet still a tiny bit experimental features that we have added, is support for CDN and other external caching solutions, like our beloved Varnish. Things are pretty tricky in this territory for what we are trying to accomplish and we really appreciate your feedback.' . '

' . '

' . 'Once again, thank you so much and stay tuned :-)' . '
