A new version of SEF Advance has been released. Version 4.8 introduces a new valuable feature: URL caching system!
When turned on, the URL cache will help reducing the load on sites with much content and high traffic. Once calculated, the URLs are cached and this copy is used next time the URL conversion is called, instead of querying the database and calculating the URL again. This method has advantage of reducing queries to database dramatically, which should boost performance on large sites with DB load issues.

You can activate the caching in SEF Advance administration where you can also set the URL cache time (default 24 hours) and flush the cache.
Note that the cache should only be activated once you have finished designing your site and don't intend to change the menu structure, section and category names etc. If you edit something like that you will need to empty the cache.

Besides caching feature, SEF Advance 4.8 also includes some optimizations, fixes and debugging improvements.

This upgrade is again free for all customers, even them that purchased SEF Advance several years ago!

To upgrade from previous versions of SEF Advance uninstall the old version and install the new one through Joomla! / Mambo component installer. Note that this will delete your settings!

If you are upgrading from version 4.6 you can upgrade keeping your settings if you follow these instructions:
- Upload and replace all SEF Advance files on your server using FTP (./components/com_sef/* and ./administrator/components/com_sef/*).
- Execute the following commands on your mySQL database (you can use phpMyAdmin):

ALTER TABLE jos_sef_config ADD `cache` tinyint(1) NOT NULL default '0' AFTER `com_exception`;
ALTER TABLE jos_sef_config ADD `cachetime` int(11) NOT NULL default '0' AFTER `cache`;
UPDATE jos_sef_config SET `cache` = '0', `cachetime` = '86400' WHERE id = '1';

Current customers can use the automatic download page to update for free.
