hook_update($node)
Respond to node updating.
This is a hook used by node modules. It is called to allow the module to take action when an edited node is being updated in the database by, for example, updating information in related tables.
To take action when nodes of any type are updated (not just nodes of the type(s) defined by this module), use hook_nodeapi() instead.
For a detailed usage example, see node_example.module.
Parameters
$node The node being updated.
Return value
None.

I know it says this for
I know it says this for hook_install, but it is missing here. If you have a module that you are developing and you start adding these, you need to whatever you put in your update hook into your hook_install as well. When installing a module, it does not execute each of these. It simply finds the highest number and sets that as the version. Hopefully this will save you some time and frustration.
