# Chapter 2. Release Notes for Photo Album 4.0.1 Final Release

Changes from 4.0.1 beta to 4.0.1 final.

- Removed photo level premission 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 noticably change the image quality.

- Minor revisions to plsql packages to improve compatability 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.
