This release has the following enhancements:

• Added support for Red Hat^TM Enterprise Linux^TM 5.7.
• Added the Pulse Sequence component to ACE software model environment.
• Added the ability to handle raw ethernet data.

This release has the following fixes and improvements:

• Enhanced URC-200 Remote Control functionality to use a longer polling mechanism with a smarter serial communication algorithm so that serial noise is suppressed.
• Improved the intuitiveness of the Open Project window.
• Previous versions of ACE stored the Durus database under the /tmp directory. The "tmpwatch" process could potentially remove the database if there was no activity for a 10 day period. This would cause the next layout install to crash Durus, requiring a reboot to fix the problem.The Durus database is now stored under /var/local/asti. There are additional checks for database errors and Durus is restarted.
• Resync FAA constants for background noise. Future changes can be tested/deployed by editing the file:
  
  /usr/local/asti/leveld/faa_bg_noise_constants.ini
• Added time and date of the capture of the source data to the spectral analysis plot generation documents.
• Added a fix for thin clients with common access to a radio to share sidetone.
• The buffers in question are used for storing received audio. When a receiver goes out of tune, the resampler buffers are not cleaned up. When the receiver goes in-tune again, new buffers are allocated.The size of the leak is based on the hold-off time. With a default hold-off of 25 ms, there will be 50KB of memory lost every time a receiver re-tunes.
• Custom component improvements.
• Added a fix for the UDP daemon to receive packets over loopback.
• After deleting a project, the user is now taken to the project list page. Previously, hitting refresh after deleting a project would attempt to delete the same project again.
• Added a fix for the "nuance-licmgr" install error message.
• Added a fix for soundfiles that have end points greater than the WAV file.
• Added a fix for "ace-create-mirror" which was failing if ISO mount point is removed.
• Added a fix for thin client on Windows^® Vista/7 which was muting speakers with certain headsets.
• Added a helper modification to support a custom component.
• Previous versions of ANZAC attempted to resolve the first IPv6 address found. If the reverse-lookup of the hostname failed, the IPv6 address was used as the hostname. This resulted in IPv4 mDNS errors. ANZAC now loops through each network interface and attempts to perform a reverse-lookup. If this fails it continues to the next interface. If all interfaces fail, ANZAC defaults to the "socket.gethostbyname()" hostname.
• Added a fix for Vox using thin client on Windows^® Vista.
• Added a fix for thin client headset presets.
• Improved the Cold Start install script.
