I’ve been on the road a bit lately, and missed last week’s shipment of the PowerShell V3 CTP2. This is the second ''beta'’ of the upcoming PowerShell Version 3. At present this only works in Windows 7 and Server 2008 R2. There are, as I understand it, no plans for this to back-port to Vista and Server 2008 R2. I do hope that MSFT DO release a version for Vista and Server 2008 RTM but we’ll see.
In the meantime, the new version has lots of bug fixes, seems quite a bit faster and in general seems more mature than CTP1. In my case, the install was a bit confusing as I’m doing a multi-boot to VHD with Windows 8 on my laptop, unfortunately, one of the partitions (of course my default) ran out of disk space so after installing the update, recovering from the out of disk space issue, Win 7 thought the update had failed. I fixed the boot problem, then re-installed the update. From the looks of it, the update also does an in-place upgrade of the CTP 1 process (although the release notes ask you to remove CTP1 first).
The new CTP has a wealth of update to the console and the ISE. With the ISE, the output and input panes are merged into a single console like pane. Very useful and much easier to use. Read the release notes for a summary of what’s new.
You can get the various downloads that make up the release here: http://www.microsoft.com/download/en/details.aspx?id=27548. From that page you can get the 64-bit and 32-bit installation packages (.MSU files), release notes and a PDF containing a description of the new ISE Features and a description of the new features in Out-Gridview.
I love this product!
