It's still possible that there will be another mini release in the 0.8 series, but right now all attention is on Hotaru 0.9, due before Christmas.
There are two main goals for 0.9. First, full HTML and CSS compliance with W3C standards, and second, compatibility with the relatively new PHP 5.3. Along with 0.9, we'll be releasing a new default theme - something a bit more professional than what is running on the demo site at the moment.
The good thing about upgrading everything
