A new include script is now available that displays recent changes to the current page. You might include this in your site's Menu area to provide insight into what's been going on with the page being viewed. You could also include this at the bottom of certain pages to provide an update on a page in progress. Use it like this:
[[include:_PageHistory]]
Here's the default output for this site's Home page. You can use CSS to style this any way you like.
By default, the three most recent changes are listed. You can specify for which page changes should be listed and specify the number of changes to include with optional paramters. See Include Scripts on the wiki for full documentation.
