  • Added support for RHEL 5.8.
  • Added credits for ALELqa component.


  • Improve health status reporting.
  • Update cold start procedure to update without requiring a reboot.
  • Added a fix for RMS which failed when trying to restore a backup with invalid characters in the filename.
  • Improve specific program component.
  • Tactical Data Link (TDL) now takes Crypto Settings into account when receiving and forwarding data. Radios with mismatched keys will not recieve data. Prior to this update, radios needed to be clear in order for TDL radios to correctly route data.
  • The maximum number of sounds was 2000, and was increased to 5000. In order to support this the XPOOLSIZE value defined in /usr/local/asti/sysconfig/soundd.ini must be increased to some larger value from the default of 20000000. The exact value needed will be a function of the sound file durations, but may require at least double or more. Once this value has been set reboot the system for the change to take effect. This configuration file is not saved as part of a system backup. It is a manual step after a cold-start. Use the following values within the Health System for guidance:
- Transmit Free Pages (if this reaches 0, then things stop working, so non-zero here)
- Transmit Pages (reports the current total allocated)
  • Added a fix for digital output power states in ACU2 and ACE-RIU firmware.
  • Added syntax checking for IP addresses.
  • Added RTI support.
  • Improved diskless installation.
  • Improved custom components.
  • Added a fix for mapping by IP addresses in the Voisus Client.
