This is actually quite an old news already, the bbPress 0.8 Desmond was already released on 8th February.
Here are some of the feature this version had improved, quoted from bbPress blog:
- Forum deletion
- Multibyte tags
- Custom locations for themes, plugins and config.php
- Multiple theme support
And these are the new features that’s added in this version, also quoted from bbPress blog: 
- Better timezone support, You’re no longer restricted to showing all your times in the timezone of your server (what an odd requirement that was)
- Whitespace preservation of ‘backticked’
blocks.
There’s a special instruction for those who want to upgrade to this version, because this version support multiple theme and you have to put each of the theme files into sub directory of my-templates, just put your current theme into any folder and upload this folder to my-templates, then activate the theme in your bbPress’ Presentation Admin panel.
