This includes SP4. It just means future security updates (which they will still release) will be targetted for SP4 and not earlier service packs.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10121832" width="1" height="1">http://blogs.msdn.com/b/sqlreleaseservices/archive/2011/01/27/end-of-mainstream-support-for-sql-server-2005-and-end-of-service-pack-support-for-sql-server-2008-sp1.aspx#10121528Fri, 28 Jan 2011 15:06:22 GMT91d46819-8472-40ad-a661-2c78acb4018c:10121528Consulting Mechanic<p>Why is SQL 2005 SP4 ending support on 04/12/2011 when it was just released in Jan 2011? <a rel="nofollow" target="_new" href="http://blogs.msdn.com/b/sqlreleaseservices/archive/2011/01/25/sql-server-2005-service-pack-4-is-now-available-on-microsoft-update-mu-amp-windows-update-wu.aspx">blogs.msdn.com/.../sql-server-2005-service-pack-4-is-now-available-on-microsoft-update-mu-amp-windows-update-wu.aspx</a>.
