What's New in This Release: [ read full changelog ]

· OAuth integration. The user experience for this sucks. I even screwed it up once when trying to follow the set-up steps while testing. Sorry about this. This process is what Twitter supports for situations like this and though I have a plan for a better experience, we haven’t had time to build it yet. Hopefully we’ll have that available soon. Until then, avail yourself of the support and FAQs provided by my HelpCenter team.
· Now relies on WordPress to provide JSON encode/decode functions (bumped the required version to WP 2.9).
· WP 3.0 compatibility fix for hashtags plugin (set default hashtags properly).
· WP 3.0 compatibility fix for creating duplicate post meta.
· Added support form to settings page.
