Killing overengineered node caching (per role combination). This strategy caches based on keys of node/1, node/2, node/3 etc. for much greater simplicity and performance. Note that this MAY BREAK your site's behavior if you have nodes that appear differently for users in different roles. Please test thoroughly before deciding to use this version. Furthermore, since I've replaced all of the node_patch.patch files for all drupal versions, you should use your current version to revert the patch before updating your code base to this version.
