Looks like the release notes page hasn't been updated since the CTP

Has a link to the release notes for the SP:
http://go.microsoft.com/fwlink/?LinkId=52072
The release notes state specifically that this is the CTP release, and is NOT for product release.
"These release notes apply to the Microsoft Exchange Server 2003 SP2 Community Technology Preview (CTP). The release notes and the software included in the Exchange Server 2003 SP2 CTP download are intended for evaluation and deployment planning purposes only,
and not for production use.
Exchange Server 2003 SP2 CTP is unsupported pre-release software distributed for feedback and testing purposes only, and is not supported by Customer Services and Support (CSS). For questions about this technical preview, see the Exchange Server Newsgroups
<http://www.microsoft.com/technet/community/newsgroups/server/exchange.mspx> or the Exchange Team Blog."
This can be very confusing for customers. Can you please ask the exchange team to update their readme file?
Thanks,
