  v2.0.0 (01/25/06) - Architecture change and major enhancements.
   - Converted modules from threads to individual daemons, simplifying the
     design and providing enhanced reliability and performance. (Jim/Bill)
   - Created watchdog daemon responsible for managing daemons and monitoring
     their health. (Jim)
   - Created state daemon to process state changes, allowing alarms to be
     persistent though a restart of any daemon. (Bill)
   - Created libstate. Allows modules to request the current state of elements,
     interfaces, and addresses as determined by the state module. (Bill)
   - Converted thread calls over to POSIX pthread functions. (Jim/Bill)
   - Converted modules internal thread interaction from a polling scheme to
     an interrupt based scheme. (Bill)
   - Rewrote trace-options support for improved functionality. (Bill/Jim)
   - Redesigned output modules/daemons to individually handle input, resulting
     in less RAM usage and better performance. (Jim)
   - Created a program to automatically generate a VIM syntax file, making it
     much easier to maintain. (Bill)
   - Introduced an adaptive back-off algorithm into the ICMP monitoring daemon,
     which handles queue congestion gracefully. (Jim)
   - Implemented conditional map-statements, which reduces interactions with
     the database, improving performance and scalability. (Jim)
   - Rewrote map-statements and policy-statements to preform few interactions
     with the database, improving performance and scalability. (Jim)
   - Created tidyd to provide time based clean up within the database. (Jim)
   - Created output syslogd daemon to replace the flatfile logging module
     in v1.0.0. (Jim)
   - Rewrote sella_nms.conf to include only basic configuration options and
     introduced sella_nms-complete.conf which includes all configuration
     options. (Bill/Jim)
   - Implemented include directory support within the configuration library
     and separated out vendor specific policies into separate files. (Bill).
   - Created admin-sella_nms.sh script to provide database administration and
     the ability to monitor incoming alarms on the command line. (Jim)
   - Improved control of state change clearing of alarms in guid. (Jim)
   - Enhanced BGP alarms to provide ASN, organization name and contact
     information. Data can be updated via the asn_data table. (Jim)
   - Created a syslog output daemon used to keep a log of alarms. (Jim)
   - Improved email daemon to support multiple SMTP servers and fixed
     minor bugs in the supporting SMTP class. (Jim)
   - Created class for tracking the rate of input. This allows the NMS
     to handle devices that flood useless information. (Jim)
   - Wrote an Administrator's Manual. (Jim)

  v1.1.0 (not released) - Minor enhancements and bug fixes.
   - Improved handling of failed database connections. (Jim)
   - Applied gui modules queue-depth to the history queue to prevent the
     queue from growing out of control. (Jim)
   - Lowered the history modules duplicate suppression from 6 hours to
     15 minutes, to reduce the load placed on the database. (Jim)
   - Identified a memory leak within libdbi and provided a patch to correct
     it. See contrib/patches/libdbi-leak_fix.patch. (Jim)
   - Enhanced history module to respond to an interrupt from a kill -HUP in
     a reasonable time frame. (Jim)


  v1.0.0 (01/19/05) - Minor enhancements and bug fixes
   - Added a duplicate syslog message detector. Protects the NMS
     from floods of duplicate syslog messages. (Jim)
   - Added a duplicate SNMPTrap detector. Protects NMS from flood of
     SNMPTraps. (Jim)
   - Added a duplicate ICMP detector. Significantly reduces the amount
     of policy work that ICMP must perform, increases scalability. (Jim)
   - Added a database connection pool to libstorage. This cuts down on
     database open/close operations and fixes the TIME_WAIT bug. (Jim)
   - Topology now merges existing discovery with new discovery based on
     hostname first, and then fails back to IP match percentage. (Jim)
   - Converted from inet_aton, inet_ntoa and inet_addr over to thread
     safe functions inet_ntop and inet_pton. (Jim/Bill)
