Changes

Variable As of version 1.3.0, the priority of variable assignments have has changed to the following priority (from lowest to highest: assignments done in locations listed first will be overridden by ones listed later): # Operating system environment variables# The "''Variables, actions''" tab of the wpkginst.exe client utility# Host XML files# Profile XML files# Package XML files For example, if you assign a variable named ''foo'' in a Profile (priority 4), it will override any existing definitions in the Host (priority 3), or by variables on the client machine (priorities 1 and 2). It can, however, be overridden by an entry in the Package definition (priority 5). In version 1.2.x and prior, the precedence order was as follows:

For example, if you assign a variable named ''foo'' in a machine Profile (priority 4), it will override any existing definitions in the Package (priority 3), or by variables on the client machine (priorities 1 and 2). It can, however, be overridden by an entry in the Host definition (priority 5). See also [[Variables#In_which_order_are_they_applied]] for some code examples, and instructions on simulating the 1.2.x behavior in versions 1.3.0 and above.
