SemanticScuttle/UPGRADE.txt

Upgrading SemanticScuttle from a previous version
=================================================

From version 0.93 to 0.94
-------------------------

- Nothing changed except for the default configuration file.
  It is recommended to start with a fresh config file,
  but not neccesary. Old config files still work.


From version 0.92 to 0.93
-------------------------

- Backup your database
- Make a copy from your SemanticScuttle Web directory
- Upgrade your database by following instructions ONE after ONE (order is important) :
#NOTHING TO CHANGE IN DB
- Upgrade your current configuration file (config.inc.php) with respect to config.inc.php.example
$footerMessage      = ''; #HTML message appearing at the bottom of the page (just above SemanticScuttle credits)
$sidebarTopMessage  = ''; #HTML message appearing at the top of the sidebar
$sidebarBottomMessage = ''; #HTML message appearing at the bottom of the sidebar
$adminsCanModifyBookmarksFromOtherUsers = true;  # 'true' if admin users can edit or delete bookmarks belonging to other users. Else 'false'.
$adminsAreAdvisedTagsFromOtherAdmins = false;  # 'true' if tags from other admins are proposed to each admin (in add/edit a bookmark page). Else 'false'.
$defaultPerPageForAdmins = 20; # default number of bookmarks per page for admins (-1 means no limit)


From version 0.91 to 0.92
-------------------------
Message: this version modifies the database to UTF-8 charset. The idea is to convert the content (through BLOB type) and then to change the tables' charsets.

- Backup your database
- Make a copy from your SemanticScuttle Web directory
- Upgrade your database by following instructions ONE after ONE (order is important) :

/* modify and add fields */

- Upgrade your current configuration file (config.inc.php) with respect to config.inc.php.example
