0.8 (cvs tag: single_nack_beta2)
    Apr 08,2002
       Allyson, Milena & Sadoc
         - Updated log functions and scripts to deal with SINGLE_NACK
         - Removed the 0.7 KNOWN BUG
         - Removed references to the DEFAULT_TIMER_VALUE vector in rmevent.c
              when RANDOM_TIMERS is enabled.
         - Update rmcastProcessRefreshPacket function to work properly when
              SINGLE_NACK is enabled.
         - New options available in the doc/rmcast.config.sample2 (see that file 
             for further info):
             MAX_NAK: indicates the max number of nacks that can be sent for each
                      sn.
             MAX_MEMBER_CACHE_SIZE: indicates how many packets we will store for
                                    each member.
         - Removed references to MAX_NAK in all files. Now we are using 
             rmcast_option.max_nak instead of MAX_NAK.
         - Removed references to MAX_MEMBER_CACHE_SIZE in all files. Now we are using 
             rmcast_option.max_member_cache_size instead of MAX_MEMBER_CACHE_SIZE.
           
0.7 (just a bkp version, not functional. cvs tag: single_nack_bkp)
    Apr 03,2002
       Allyson & Milena
         - Bounded, correctly this time, the max number of nack that we can
               send for a packet when using SINGLE_NACK. This number of nacks is
               bounded by the MAX_NAK constant, defined in rmstruct.c
         - Removed some bugs related to the insertion of events when using
              SINGLE_NACK.
         - New debug defines in Makefile:
              Now if you want to debug the FULL cache content you must define
                  DCACHE_CONTENTS in addition of DEBUG_SHOW (see Makefile for
                  further info)
              Now if you want to debug the FULL message content you must define
                  DMSG_CONTENTS in addition of DEBUG_SHOW (see Makefile for
                  further info)
         - KNOWN BUG: sometimes, in a event list node,the IP string and the PID
              change their values to strange ones. This stops the sending of 
              nacks and, in consequence, the sending of data to the application. 

0.6 (cvs tag: single_nack_beta1)
    Mar 31,2002
       Allyson
         - Removed some bugs related to the SINGLE_NACK feature.
         - Added new fields to the log file to support SINGLE_NACK mask logging.
         - Updated tools/scripts/rmcastplot.bash script to deal with the new 
             fields in the log file.
         - Removed some old scripts from the CVS repository.
         - Fixed some (not all) FIXME requests in some files.
         - Improved debug messages.Now we can "barely" understand what they said
         - Implemented generation of UNIFORM random timers. (You must define 
             DRANDOM_TIMERS to enable it. See Makefile for details)
         - New options available in the doc/rmcast.config.sample2 (see that file 
             for further info):
             TIMER_LOWER: this option replace the old AVG_DELAY option. It's the
                          lower bound for the random timers
             TIMER_UPPER: the upper bound for the random timers
             TIMER_DISTRIBUTION: the distribution for the random timers. By now
                                 the only possible distribution is UNIFORM.
        
0.5 
    Mar 19,2002
       Allyson & Milena
         First try in optimizing nack sending (compile with SINGLE_NACK to 
             enable this feature. See Makefile for details)
0.2

       Allyson
         Included one example application (see the examples directory)

        Allyson
          Included REFRESH_TIMER option in the option file
0.2pre6
     Feb 04,2002
        Allyson & Sadoc
          Several bug fixes regarding SUPPORT_FOR_NEW_USERS.
          Using new TGIF(QPL) version 4.1.41.82
          We have created a configuration file (see doc/rmcast.config.README e
            doc/rmcast.config.sample). Now the user can set the protocol
            through the options in that file.
          Now TGWB has no need to define SUPPORT_FOR_NEW_USERS (use rmcast.config
             instead)
          Now "Unicast Mode" is available
          Updated CONTENTS file
0.2pre5
     Nov 22,2001
        Allyson, Milena & Sadoc
          Started testing SUPPORT_FOR_NEW_USERS blocks.
          The protocol running without the SUPPORT_FOR_NEW_USERS is working well.
0.2pre4
     Nov 12
        Allyson, Milena & Sadoc
          We did some changes regarding RedHat 7.2 gcc compability.
          We didn't test SUPPORT_FOR_NEW_USERS routines.
0.2pre3
     Oct 30
        Allyson, Milena & Sadoc
          Finished first level of SUPPORT_FOR_NEW_USERS
          Obs: The TGWB Makefile,wb.c and mainloop.c files were update too.
0.2pre2
     Oct 22
        Sadoc & Milena
          Added some routines related to the support for new users.
          The changes can be activated defining SUPPORT_FOR_NEW_USERS constant.
          Obs: The TGWB Makefile,wb.c and mainloop.c files were update too.
