All the changes in 1.52 are in the stream template, and a little addition to Fargo's CMS to support the new stuff. And all the changes are fairly technical.
Maps are the big 1.52 feature. Here's a narrative.
You can use maps in the backgrounds for days by attaching attributes to the headline for the day. This feature will get separate documentation.
Thanks for Ken Smith's suggestion to include the italic and bold versions where available.
Fixed a bug where if you went to a permalink without subs (example), it would flip the wedges on all items that did have subs. A jQuery newbie mistake.
The title of each page now has the site name in square brackets. The home page is given the name "home," it would otherwise be the empty string.
Updated the fargoTemplates repository on GitHub.
There's now a connection between the attributes on the day page in the outline and the <div> representing the day in the rendered HTML. This is how the data is transmitted from Fargo to the page for the new map feature.
It took a while to figure out how to do this mapping, but this is exactly why the data-xxx feature is in HTML, what's interesting is how nicely it maps onto the structures we're already maintaining in the CMS. The worlds match up nicely.
