    doc/CHANGES3.0
- New struct members (currently not used)
  - player.comhistory command history (for debugging) last 10 commands
  - nat.nat_mission_trigger set which relation you want to trigger
    various missions and autodefenses at.
  - Added land.lnd_scar -- how experienced the land unit is.
  - Added type field to all objects so they can identify themselves
  - Moved var structs to the top of all class structs for easy location
    (see struct genchrstr defined in h/genitem.h)
  - sect.sct_mobil was changed form unsigned char to short (to permit
    the removal of updates--note I don't plan to remove updates, but
    someday someone might try and they will need this so that sectors can
    go to negative mob).
- New struct members (currently used):
  - nat.nat_hostaddr, nat.nat_hostname, nat.nat_userid, userid and hostname
    of last person to connect to that country.  If when you login,
    your userid or hostname is different from the last person to conenct
    to that country, then you will get a message like:
Last connection from: Mon Nov 13 01:48:04 1995
                  to: Mon Nov 13 01:48:12 1995
                  by: children@RedDragon.Empire.Net
    this will improve security and be helpful for co-rulers.  Also
    added were nat.nat_last_login and nat.nat_last_logout.
  - Nation now has 50 realms.
- New global constants:
  - Extended nsc ("next selection conditionals" e.g. cen * ?mil=5) to
    support C_SYNC messages and include the objects "map" (bmap), and "nation".
    These will transmit to the client the equivalent of "dump", "ship",
    "car", "land", "lcar", "bmap", and "nation" output and more.
  - Added nsc entries for the following classes: sect, ship, plane,
    land, nuke, map, item, product, and version.  These will transmit to
    the client the equivalent of the "show" and "version" command output
    and more.
