• Page security allows you to dictate exactly who can view and edit your pages. Some people can edit your pages, some can view and everyone else can’t see a thing. Security is as finely grained as you want it to be.
• Kisimi now comes with an upgrade option at installation time and things are a little smarter. Installation can take less than 2 minutes!
• Longer pages with headings can automatically generate a table of contents section.
• Users can specify a timezone so that the dates and times are relevant to their location.
• Administrators can prevent new user sign ups. Handy for those sites publishing their documentation and support pages to the world.
• Any user with an email address listed at www.gravatar.com has their avatar image appear in their preferences.
• Tidier user interface with plenty of little shiny bits.
• Plenty of bug fixes including those messages for PHP configs that show all warnings. It’s still recommnended that PHP is configured without warnings for production servers.

There’s also a comment about one of my favourite subjects – reading too much into statistics. Apparently Jimmy Wales (Wikipedia co-founder) looked into who was responsible for most of the articles changes and found that 0.7% of users were responsible for over 50% of all edits. But an “edit” may be a spelling correction rather than adding content or altering the facts or meaning in an article. As it turns out, the data points to these hyper-active users doing just that – cleaning up after everyone else.

Kisimi uses a basic string comparison function called simple_text() to show the relative difference between two versions of a page. We could also use the Levenshtein function which gives the minimum changes to go from string A to sting B, but that doesn’t always make much sense for larger content changes. If someone sees that two versions are 96% the same then it’s obvious they’re much the same.
