Changes from 4.0.1 beta to 4.0.1 final.
Removed photo level permission checks. Load testing showed that allowing different photos within the same album to have different permissions made the queries to get the photos in a large album very slow. I changed the application logic so that all photos in album have same permission and permission check is done at the album level.
Tunned numerous queries base on load testing results against a database filed with 10,000 photos.
Made compatible with acs-kernal 4.1.1 and acs-templating 4.1.
Added caching of primary keys of photos in an album and package root folder_id.
Added optional permission check when serving images.
Added separate optional page to display the base sized photo.
When uploading a photo, the thumbnail is now created from the viewer sized image rather from the base sized image. Creating a small image from a medium-sized image is much faster than creating a small image from a large image and does not noticeably change the image quality.
Minor revisions to plsql packages to improve compatibility with acs-content-repository.
Added more detailed documentation in both html and docbook format.
Fixed name conflicts with photo album lite.
Besides upgrading the rest of your acs intall to 4.1.1, you will need to mannually run photo-album/sql/plsql-packages.sql through sqlplus to update the packages inside oracle when upgrading from the beta to final version of the photo-album.
