If you already have Gnosis installed, and are upgading, make sure you have first installed gnosis 1.0.9b. This will prepare Joomla!'s update SQL system to handle the database changes. After you have installed com_gnosis1.0.9b, then you may install com_gnosis1.1.0.
If this is your first time installing Gnosis, then simply download this version and install as normal. Installing 1.0.9b first is not required for first time installs.
This version adds a date created, date modified, tags, and source fields. It also changes the way the admin chooses which fields to show. Now, in addition to choosing which fields to show, the administrator can choose in which order the colums display. This is achieved by entering a comma delimited numeric list corresponding to fields in the gnosis administrator options. More specific instructions about which fields correspond to which number are listed in the administration.
A quick example, however, is if one wanted to display only the term and definition, then one would enter 0, 3 in the administration option.
If upgrading, please install com-gnosis version 1.0.9b first. First installs need only install this version.
Because this upgrade changes the gnosis database, please backup your Joomla! database prior to install.
