Change to ImageCache API causes problems...

This is just a heads-up, perhaps you already know...
A new version of ImageCache is nearing release (imagecache 5.x-2.0-beta http://drupal.org/node/204475) I tried this with LightboxV2, which was working before I upgraded imagecache) and get the following error whenever I try to interact with imagecache now (e.g., attempt to edit pre-defined preset):
"Fatal error: Call to undefined function _imagecache_get_presets() in lightbox2.module on line 482"

It looks like the new API calls this function imagecache_presets(), but I have not attempted to try any fixes.

Thanks for a great module - it works so transparently!
