Sweet! SQL Server 2014 CTP1 is now available for download at Microsoft.com! Get it while it is hot, and start your evaluations. You can also download the product guide here so you can know exactly what has changed and what new features matter the most to you!
The most promising new feature for me is In-Memory OLTP, formerly known as project Hekaton! I’m very excited about this, and cannot wait to start tinkering with it. Download and let me know what features you find the most compelling!
