The latest (and final) Beta for what we used to know as Visual Studio CodeName Orcas has now been made available. Visual Studio 2008 Beta 2 can be downloaded from here.
According to the team at Microsoft, this version is now feature complete. The next version - RTM version - will ship before the end of the year and the final product release is scheduled for February 2008.
Although still a hefty download, it's less bulky than the previous Beta and the Community Technology Preview (CTP) versions. As with all Betas, the best advice is to install it on a development machine that you don't mind reformatting if necessary.
