[etch-users] Etch 4.0.0 released

[Jason H. <jh...@ap...>]

Significant changes:

* Server upgraded to rails 3.2.3 from 2.3.14
* Search functionality in server now uses ransack[1] rather than custom code.
* Graphs on etch server dashboard now use Javascript via flot[2] instead of flash

Minor stuff:
* The client should now handle Unicode encoding properly when running under ruby 1.9 so that if the output captured from operations includes non-UTF8 characters they'll be replaced by something valid rather than causing the server to reject the message.
* Fix interactive mode so that it works again

Notes:

The GettingStarted page on the wiki has been updated to reflect how to get Rails 3 up and running.  Note that Rails 3 requires ruby 1.8.7, 1.9.2 or 1.9.3.  The client should still run under any version of 1.8 or 1.9.

The server search engine change breaks any custom search bookmarks you might have.  If you need help figuring out the new syntax just ask here on the list.
