If anyone feels like trying out the next version, you can download it from http://downloads.wordpress.org/plugin/nextgen-facebook.3.7.zip.
The new features in version 3.7 are:
* Added code to fetch the preview image URL for videos from Vimeo using Vimeo's API.
* Moved the caching object (and it's configuration variables) from the buttons class to the main NGFB class. This was necessary in order to use the cache object's
curl() features for Vimeo's API.
* Added a
$cache = 'file' default argument to the cache
get() method - by passing it
$ret = 'raw' and
$cache = 'wp_cache', it's possible to use the method to raw fetch content (like an array from the Vimeo API).
* Renamed the
apply_content_filter() method to
get_filtered_content(), and added WP object cache code to save the filtered content. This should improve performance (slightly) for websites without caching plugins.
* Added a
NGFB_WP_CACHE_EXPIRE constant with a default value of 300 seconds.
Please let me know if you have any issues.
