Client: Version 2.9001.477 is the lowest version that RC5-72 results will be accepted from. (Results from beta builds of v2.9000 will be discarded). All v2.9xxx clients require a minimum upstream proxy/server version of at least build 330.

Personal Proxy: Build 331 is the minimum recommended version for supporting v2.9xxx clients (though the beta proxyper of Build 330 will function). Proxy build 331 requires a minimum upsteam proxy/server version of at least build 331.
