Why upgrade? I'm not a lawyer, but here's my take on the differences
to version 2:
* Software patents: better protection against abuse of patents to
prevent users from exercising the rights under the GPL. I doubt
we'll get hit with a patent suit, but it's a good move just on
general principles.
* License compatibility: compatible with more free licenses, i.e. can
"steal" more free software for use in Empire. I don't expect to steal
much, but it's nice to have the option.
* Definition of "source code": modernization of some details for today's
networked world, to make it easier to distribute the software. Not
really relevant to us now, as we normally distribute full source code.
* Tivoization: this is about putting GPL-licensed software in hardware,
then make the hardware refuse to run modified software. "Neat" trick
to effectively deny its users their rights under the GPL. Abuse was
"pioneered" by TiVo (popular digital video recorders). GPLv3 forbids
it. Unlikely to become a problem for us.
* Internationalization: more careful wording, to harden the license
outside the US. The lawyers tell us it better be done that way.
* License violations: friendlier way to deal with license violations.
This has come out of past experience enforcing the GPL.
* Additional permissions: Probably not relevant to us.

Old version recognizes the first ':', which prevents use of ':' in
host names. They are used in numerical IPv6 addresses. New version
recognizes the last ':', which prevents use of ':' in service names.
Old version treats empty host or port specially (use default).
Documentation suggests ':' is required, but the code doesn't do that.
Instead, the argument is interpreted as host, even when it's empty.
New version makes the HOST: part optional. You can't specify host and
default the port. Tough. Keeps documentation and code as simple as
possible.
Compare:
old version new version
argument host port host port
"" "" default default ""
"A" "A" default default "A"
":" default default "" ""
"A:" "A" default "A" ""
":B" default "B" "" "B"
"A:B" "A" "B" "A" "B"
Three options: abort, crash-dump, nothing. crash-dump works by
aborting a fork. It isn't implemented for Windows.
The oops action is no longer tied to daemon mode, but -d still implies
-E abort for convenience.
empdump exports and imports game state as plain text. Limitations: it
currently can't export player bmaps, power report, telegrams,
announcements, message of the day, no-login message and log files.
Exported floating-point values may be inexact. Importing an exported
game state may not result in identical data files; besides the loss of
floating-point precision just mentioned, coordinates are normalized,
and characters beyond a string's terminating zero in a character array
are lost. Bug: importing resets timestamps to zero. It should set
them to the current time.
Commit 530deef2 failed to update .TH of fairland(6), files(6) and

Commit 530deef2 failed to update .TH of empire(6).
Commit eeb9d3cb created empsched(6) with the wrong .TH.
a seed for the random function.
(nightlybuild.sh): Add the -R 1 for the server.
(nightlybuild.sh): Switch to -R 1 for the fairland as 1 is safer.
Some systems might generate lousy randomness from a
zero seed.
(prng.patch): Not required anymore, -R 1 is used instead.
(main, emp_server.6): Rename -r and -R to -u and -U. "-R" is now used for random seed.
(schedulefil): New.
(set_dirs, set_paths): Rename. Initialize schedulfil.
(read_schedule): New. Can read several updates, which will be used in
later changesets.
(update_time): Change to array. Will be used in later changesets.
(update_schedule_anchor): New.
(update_init): Initialize it.
(update_get_schedule): New.
(update_init): Call it to initialize update_time[].
(update_sched): Rewrite.
(update_forced, update_wanted): Replace.
(update_reschedule): New.
(main): Call it on SIGHUP to reload the schedule.
(update_trigger, update_force, force, player_coms): Drop force's
capability to schedule updates in the future, because it's not worth
the trouble to implement again. Deities can simply edit the schedule
file to schedule updates. Remove update_force() and
update_trigger()'s parameter.
(upda): Update for new scheduler. Take care to keep output the same
as far as possible, even though it's ugly, to avoid breaking clients.
(update_policy, adj_update, update_times, hourslop, blitz_time):
econfig keys removed.
(update_demand, UPD_DEMAND_NONE, UPD_DEMAND_SCHED, UPD_DEMAND_ASYNC)
(update_demandpolicy, UDP_NORMAL, UDP_TIMES, UDP_NORMAL, UDP_BLITZ)
(UDP_MAX, UDP_DEFAULT, UDDEM_TMCHECK, UDDEM_COMSET, UDDEM_DISABLE)
(UDDEM_MAX, UDDEM_DEFAULT): econfig key and values replaced. Users
changed. wantupd.h is now empty, remove.
(demand_check): External linkage.
(update_policy_check): Now pointless, remove.
(is_daytime_near, min_to_next_daytime, regular_update_time)
(scheduled_update_time, next_scheduled_time, updatetime)
(next_update_time, next_update_check_time): Unused, Remove.
(demand_check, demandupdatecheck): Move call of demand_update_time()
from demand_check(), which controls all demand updates, to
demandupdatecheck(), which controls only unscheduled ones. Fixes
update command not to lie about the next scheduled demand update.
(demandupdatecheck): Check updates_disabled() so that zdone no longer
claims to trigger an update when it can't.
(login): New parameter utf8. If set, request option utf-8 from
server.
(expect, recvline): Split recvline() out of expect(). Replace or
remove some unhelpful diagnostics.
(eight_bit_clean): New.
(screen): If eight_bit_clean is set, highlighting is switched with
SO/SI. Else characters with MSB set are highlighted.
(main): New option -u to request UTF-8 and set eight_bit_clean.
unclear. Other programs only support -e. Remove -D.
(install_service): Remove argument datadir_set.
(main): New option -v.
(main): Exit successfully after -h.
(main): Don't print usage on unknown options, just point to -h.
(print_usage): Rewrite. Deprecate use of non-option arguments.
Get it from environment variable LOGNAME if set,
else get the user name from the system.
(main) [_DWIN32]: Add stdin redirection ability to the Win32 port.
The client reads until stdin redirection empty and then terminates.
