#753 improved the install messaging. Instead of rendering just the database update information, the version of the new Event Gallery package is now visible as well. This might help to avoid confusion about version numbers. The database is not necessarily at the save version as the code.
#754 Load the template engine Smarty only if necessary for sending a mail. From a programming perspective this is bad, but it increases compatibility with some other components.
#752 make the download of a zipped order containing image hosted by Google Photos work.
#755 Picasa: avoid too many requests against svenbluege.de in case the picasa token is invalid. Picasa will continue working with this version. Older versions will not be able to load data from Picasa anymore.
