If you want to try the current development version of pasdoc, you are always welcome to download and compile current pasdoc sources yourself. See SourceForge SVN instructions and CompilingPasDoc.
If you don't want to compile pasdoc yourself, you're still welcome to download and try pasdoc snapshots, available at http://pasdoc.sourceforge.net/snapshots/.
Notes about these snapshots:
While they identify themselves as x.y.z version (e.g. 0.9.0 or 0.10.0), remember that actually they are not x.y.z version of pasdoc. They are just a snapshot of pasdoc development state at some point.
Right now these snapshots are not generated automatically. I'm willing to manually create and upload them when someone asks for them. So if you want to check some latest pasdoc feature and you want me to create latest pasdoc snapshot with this feature, just subscribe to our MailingList and send a mail asking for a new snapshot.
