[etch-users] Etch 3.5 release

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

Etch 3.5 has been released:

Replace REXML for XML parsing with LibXML. Uses less CPU, which  
improves scalability, and adds support for DTD validation.  config.xml  
files are now validated against config.dtd after filtering.  This was  
the behavior in etch 2.x and earlier, but has been missing in etch 3  
until now.  You will need the libxml-ruby gem on your etch servers  
(which in turn requires the libxml2 library, which comes with most  
Linux distros).

Added some Flash charts to the web dashboard to graphically show  
client count and status.  The necessary libraries come in the etch  
distribution so there are no new dependencies for this feature.   
Clients without flash will see no change.

Converted the cron job wrapper script from Perl to Ruby so the client  
package no longer depends on Perl.

Various other minor bug fixes.
