Just before the US September holiday weekend, the first Refresh for Designer 4.02 was released. (Aug 31, 2012).
Initially I thought that this was what used to be known as Auto Updates and had been renamed to Refresh. But this is apparently a quick release to fix some important bugs.
You can go get it, if you go to the Help menu, Check for Designer Updates. There is no standalone download yet. (Auto Update 2 for Designer 4.01 eventually got one). However, if you have a Designer instance behind a firewall with no internet access you can just go to a Internet friendly workstation, open a browser to:
Download the entire file structure, (wget is your friend) copy it over to the protected server (somehow) and then you can point your Designer instance to it, with a URL format of something like:
file:///c:/path/to/file/structure (Where the end node is the directory with the site.xml file. Note the three forward slashes) On Unix file systems, obviously the path is simpler, no need for c:/ stuff.
Auto Update 1 is still pending, and looking at the bug list for that one, I see some interesting bugs fixed, looking forward to its release!
