Updating versions of Joomla between 1.6.0 and 1.6.6

The introduction of Joomla 1.6 brought in several new features, one of which was 'Automatic update'.  Because of the changes made in the databases during the various releases of 1.6 and 1.7 'Automatic updates' is best not used for Joomla versions below 1.6.5.  Using 'Automatic updates' for 1.6.5, 1.6.6 and 1.7.0 has to be done twice to bring Joomla up to the current version.

        1. Login to the administrator control panel of your Joomla.
        2. Navigate to ... Extensions >>> Extensions manager ... and click the 'Update' tab.
        3. Then 'Purge cache' ... 'Check for updates', select the Joomla update and click the 'Update' button.
          1. If no updates are found then install Joomla_1.6.0_to_1.6.6-Stable-Patch_Package.zip
        4. Log out then repeat steps 1 to 3.
        5. Log out and back in again.
        6. Navigate to ... Extensions >>> Extensions manager ... and click the 'Database' tab.
        7. If any errors show then click the 'Fix' button.
