SQL Server 2005 Service Pack 4 is RTM

SQL Server 2005 Service Pack 4 has just been released a few days ago.
You can download files here:
The SQL 2005 SP4 Readme file
Download SQLServer2005SP4-KB2463332-x64-ENU.exe for X64
Download SQLServer2005SP4-KB2463332-x86-ENU.exe for X86
Download SQLServer2005SP4-KB2463332-IA64-ENU.exe for IA64
Be sure you read the Readme and release notes files and be sure to test in a test environment first before you push it out to production environments.
Good luck!
