Confluence 2.9 and above. Confluence 2.10 or above is required for Anti-XSS support. Tested on Confluence 2.9.2, 2.10.3, and 3.1. Tested with FireFox 3.5/3.6, IE 8, Safari 4, and Chrome. May work on earlier versions of Confluence, but it is not supported on earlier versions and requires the server is running JVM 1.5 or above.
See below for a warning for current Macro security plugin users.

After a Confluence restart or after initial install, run macro may display extraneous text: (). Disabling and then enabling the plugin resolves the problem. Because of this problem, this release will only show Confluence 3.x compatibility in the Plugin Exchange and, therefore, the plugin repository.
