Version 9 is out on the auto-updater.
Version 9 2008-08-08 12:00:00
This is a big update so the automatic update happens in two steps. Do not be alarmed.
There are way too many changes to list, but here are the hilights:
Blockland v9 Windows
Blockland v9 Macintosh
Note: The installer contains a mechanism for backing up old v8 add-ons but if you are a developer you may wish to back up your code manually first.
