The main improvement is that Aether can now be used as an Apache ErrorDocument. This was suggested by Neil Brown, and allows all sorts of nifty things:
- Overlay Aether over an existing HTML web-site, allowing a gradual/partial transition to Aether rather than all at once.
- Different passwords for different areas of a site, or even a passwordless wiki area: just use multiple copies of Aether. One copy may even be in a subdirectory of another!
I've also decided that one of the main goals of Aether is code readability. I figure that with clean readable python code it'll be possible to add to Aether without a huge learning curve. The GPL is not much good if only a few elite hackers can understand your code.
