Okay, this is not yet the much anticipated "Phoenix" release, BUT...
This new release combines the stability of the previous 0.9.0.x releases with massive performance improvements. You may actually have noticed it on the b2evolution.net site itslef. On average "Dawn" runs 2 to 3 times faster than the previous "Amsterdam" release.
If your hosting provider has ever told you your b2evo was using too much resources, you'll definitely want to use this new version!
But that's not all. Even if b2evo was already fast enough for you, you have most probably been annoyed by increased amounts of spam this summer. That's not b2evo specific. Just every site on the planet with any form of feedback is subject to this... Well, we have extended our antispam features by various means in order (a) filter more spam and (b) make the blacklist management somewhat easier.
There's also a few plugin goodies in here but of course, the bulk of new features will be in "Phoenix". There will be an ALPHA release of Phoenix shortly but it won't be as stable as this release. Thus, we strongly recommend everyone upgrades to 0.9.1 without further ado ;) and we're doing our best to get "Phoenix" out.
Here's a quick rundown of new features in 0.9.1 "Dawn":
Scalability: Speed improvements, especially on loaded systems. (fplanque)
Extended browsing capabilities (fplanque)
Trackbacks & Pingbacks will be shown on the "last comments" page (fplanque)
Wacko markup plugin (fplanque)
WikiLinks plugin (fplanque)
Antispam: (fplanque)
Referer spam gets detected early and triggers a "403 Forbidden" error message in order to save resources on the server.
Removed public statistics in order not to attract referer spam.
Trying to access public stats triggers a "410 Gone" error message.
Complete comment text will be searched for blacklisted keywords.
HTML entities can now be used in blacklisted keywords.
Restricted URL input into feedback to defeat comment spam.
Use of rel="nofollow" for feedback author URLs to defeat comment spam
The antispam blacklist is not displayed by default anylonger if it gets longer than 100 entries (and it will indeed get much longer than that...)
Upgrade information:
You'll need to run the install script to upgrade your database
