Just in case you missed these three notable releases so far this month...

SQL Server 2008 has Released To Manufacturing (RTM) and is available for download by MSDN and TechNet subscribers. There's also a free 180-day Full Trial and Express Edition which are available for download by everyone.

Following that up is a pair of complementary releases: .NET Framework 3.5 Service Pack 1 and Visual Studio 2008 Service Pack 1.  The .NET 3.5 SP1 includes performance improvements, ADO.NET Entity Framework and Data Services, and a version of the .NET runtime optimized for clients which weighs in at under 28 MB. On the VS2008 SP1 side of the house, there are both new and improved designers, improved VSTS features, and new controls. Plus both service packs provide support for SQL Server 2008. And a bunch more.

Scott Hanselman blogged a nice guide to the combined service packs.
