- Modern markup
- Mostly a subset of WikiCreole, except with a completely different LinkSyntax.
- Modern HTML
- Generated pages normally validate as HTML5 (though it's possible to break that), and CSS is supported. We're not in 1995 anymore.
- UTF-8 support
- While page names are restricted to ASCII characters, page contents are handled as UTF-8, permitting a wide range of characters.
- Page transclusion
- Can be used as a poor man's redirect, plus other things.
- Flat-file storage
- Pages are saved as ordinary text files on disk, making them easy to backup, inspect or change from outside WabiSabi.
- Page backups
- The previous two versions of any page are saved. A future release will probably offer access to them.
- Captcha
- The simplest possible system, based on a fixed password. Before you ask, yes, this is effective, and also allows for a non-public wiki simply by hiding the password.
- Recent changes
- On the other hand, it should be easy to watch when pages are changed, in order to catch vandalism quickly.
- Universal Edit Button
- See http://universaleditbutton.org/Universal_Edit_Button
- Plugin support
- Allows creating extra wiki actions and markup plugins, and replacing or modifying the built-in templates, without any changes to the core file.
Plugins
- Wanted pages
- Finds and displays all links to non-existent pages on the wiki.
- RSS newsfeed
- Renders the recent changes as a newsfeed in RSS format, making it easy to monitor automatically.
