This plugin is only for WordPress 2.3 or later. Earlier versions of WordPress did not have the plugin update notification system, therefore do not need this plugin.
The plugin has two ways of installation, because on fresh 2.3 installations the update-check will take place before you were able to activate the plugin.
update.php is a patched version of wp-admin/includes/update.php
wp-admin/includes/update.php file.wp-admin/includes/ directory.plugins admin page savely.anonymous-plugin-updates.php is the actual plugin.
wp-content/plugins/ directory.
