Param dir of block type file/image needs to be relative to the uploads dir only. 
There is no image uploads dir used anymore.
 (maybe this will be re-introduced later but this depends on the CMSms developers choice 
how to handle the dir with the {content_image} tag)

The param "filter" has been removed. 
Use the new params "exclude_prefix", "include_prefix", "exclude_sufix" or "include_sufix".

AdvancedContent 0.5.* series will be the last one with a built in filepicker. 
In version 0.6+ the filepicker will be removed and replaced by a standalone filepicker module 
that needs to be installed separately.

The SVN path of version 0.5.* series is no longer /trunk/ but /tags/0.5.+/
