*
2008-08-14 08:30:38 +02:00
* The steps for the upgrader for after the new release is downloaded and
* unzipped is :
* 1. Test unzipped location for select files to ensure that unzipped worked .
* 2. Create the . maintenance file in current WordPress base .
* 3. Copy new WordPress directory over old WordPress files .
* 4. Upgrade WordPress to new version .

* 7. Remove old files .
* 8. Delete 'update_core' option .
*
* There are several areas of failure . For instance if PHP times out before step
* 6 , then you will not be able to access any portion of your site . Also , since
* the upgrade will not continue where it left off , you will not be able to
* automatically remove old files and remove the 'update_core' option . This
* isn ' t that bad .
*
* If the copy of the new WordPress over the old fails , then the worse is that
* the new WordPress directory will remain .
*
* If it is assumed that every file will be copied over , including plugins and
* themes , then if you edit the default theme , you should rename it , so that
* your changes remain .
