- new feature : RSS notification feed. Feed generator is an external tool
(FeedCreator class v1.7.2). New file feed.php - new database field : comments.validation_date (datetime). This field is required for notification feed. - new database field : users.feed_id (varchar(50)). users.feed_id is an alias of users.id but is much more complicated to find (50 characters, figures or letters, case sensitive) : the purpose is to keep it secret (as far as possible). - new database field : users.last_feed_check (datetime) - new database field : users.registration_date (datetime) - bug fixed : no need to add the (unavailable) session id to install.php in the installation form. - modified database field : images.date_available become more precise (date to datetime). This precision is needed for notification feed. - new index : comments_i1 (validation_date). Might be useful for feed queries. - new index : comments_i2 (image_id). Useful each time you want to have informations about an element and its associated comments. - version 9.11 of mysqldump outputs database field names and table names with backquote "`" (didn't find how to take them off) git-svn-id: http://piwigo.org/svn/trunk@801 68402e56-0260-453c-a942-63ccdbb3a9ee
