Best new feature of BBEdit 8: the live preview that updates as you edit Web pages can now be retrieved from your Web server rather than just rendering the local source file. This means that your PHP (or, in my case, ASP) code gets executed and shown in the preview.
It says you need the Web server to be "local," but it works fine with an IIS inetpub folder mounted via SMB over a LAN. I created a HTML Web Site pref entry for JerryKindall.com, specified /Volumes/Inetpub/wwwroot as the "local" path to the site and http://gabriel.tamaron.net/ as the URL where the pages are actually published (that's the internal 192.168.x.x hostname I use for the server, so it happens at LAN speed). When I edit pages, I see them update immediately, as BBEdit saves my changes to a temporary file on the Web server via file sharing and then calls up the page from the same server using WebKit in the corresponding Preview mindow.
Anyone who uses PHP, ASP, JSP, or even SSI and edits pages on a Mac needs this update.
