First, apologies for the god-awful formatting of my posts just now. I just reinstalled, and I haven't got anything decent to post with - the .Text web page that I'm using right now sucks. Anyway.
I just posted FlexWiki 22.214.171.1249 to the SourceForge website (http://sf.net/projects/flexwiki). This is primarily a bugfix release. Given that our last official release was in late 2005, there are a fair number of bugs that have been fixed, too. There are also some minor feature enhancements - you can check out the change list on the project website.
There are three reasons that it's been so long since the last official release: 1) We've been focused on FlexWiki 2.0. More about that soon. 2) We do continuous integration at http://builds.flexwiki.com, so anyone that wanted updated bits could have gotten then from there any time. 3) We haven't had a release manager, so posting bits on SourceForge has been low priority. Hopefully #3 will change soon - we're working on it.
As always, the best place to get support with FlexWiki remains the flexwiki-users mailing list. You can subscribe via the FlexWiki project website.
