Do spatial functions still use MBR?

Hi,

I was reading through several posts here, along with blogs/posts in the web about GIS capabilities of MySQL. A lot of these posts state that MySQL uses the MBR instead of the entire polygon to do a spatial search. Is it still the case? If this has been fixed, please point me to the version of MySQL with which this support has been added.
Also, it would be great if you can point me to a page showing the supported GIS spatial functions.

Another question is on InnoDB support for spatial data. Reading through the page (http://dev.mysql.com/doc/refman/5.0/en/innodb-restrictions.html), I see that though InnoDB can be used to store spatial data, spatial indexes are not yet supported.

Thanks,
Sunil
