* improved Editor's map interface
* tabbed info balloons
* custom markers
* support for multiple languages
* inset navigation maps
In addition, the installation process has been greatly simplified
compared to 0.6; you only have to hack the MediaWiki templates if you
want to enable path support, which is disabled by default. I've also
refactored a lot of the code to make it easier for developer-types to
tinker with it.
Anyway, check out the installation guide (new URL!):
