SemanticScuttle/doc/UPGRADE.txt

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

From versin 0.94 to 0.95.0
--------------------------
The file structure completely changed in 0.95.0 compared
to previous versions. We recommend that you start with a
fresh installation, just copying over your config.php file.
Set your web server document root directory to www/.

Yes, we kind of lost the ability to run SemanticScuttle
in a subdirectory of a hostname. This functionality will
be back in one of the next releases, but for now, you have
to live with it.

Update your database:
- ALTER TABLE `sc_bookmarks` ADD `bVoting` INT NOT NULL;
- ALTER TABLE `sc_bookmarks` ADD `bVotes` INT NOT NULL;
- Add the new votes database table. See data/tables.sql.

Currently, only MySQL can be used as database backend.
All other DBMS (database management systems) have not been
tested except for PostgreSQL, and SemanticScuttle fails there.

The de_AT translation has been re-added. This is because
de_AT provides a rather ugly "official German" style,
while the normal de_DE is friendlier. Choose what you like.


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.
- If you used translation de_AT, please switch to de_DE.
  de_AT was moved to de_DE and de_AT has been removed.


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) :
