Well, I should have started a changes file long, long ago.  Oh well,
I'll start one now.  Hopefully, I'll maintain it.  JE.


8/31/94 JE      Added a GET_REAL_LEVEL macro which returns the actual
                level taking switched characters into account.  Used
                in CAN_SEE so that switched immorts can't see invis
                gods.

8/31/94 JE      Added restriction to interpreter.c so that immort commands
                cannot be used by NPCs.  Removed all the IS_NPC checks from
                the individual god commands since they are now redundant.

8/31/94 JE      Made newsign.c into sign.c and deleted the old DIKU sign.c.
                newsign.c forks to handle its kids and is generally more
                concise and robust.

8/31/94 JE      Changed the type argument of affect_from_char and
                affected_by_spell to sh_int (from char) to match the fact
                that the 'type' member of the affected_type structure is
                now a sh_int instead of a char.  Spotted by Jean-Jack
                Riethoven.

8/31/94 JE      Fixed MIN statement using uninitialized 'water' var in
                spell_create_water.  Spotted by JJR.

8/31/94 JE      Ken Cavness noted that MOBs were getting past guildguards.
                Not surprising, since I changed the relationship between
                do_move/do_simple_move/perform_move so many times.  The
                discipline has now changed again; MOBs calling perform_move
                must call with 3rd arg of 1 instead of 0.  Changed the
                arg from 'following' to 'need_specials_check' so its purpose
                would be clearer.

8/31/94 JE      Added 'worn_on' short integer to obj_data structure to go
                with worn_by char_data pointer.  Indicates which eq pos
                eq is being worn on.  (Will be used to facilitate a cleaner
                version of objectmagic.)

8/31/94 JE      extract_obj now automatically unequips the obj first if it
                is being used as equipment (uses worn_by and the new worn_on).
                do_use no longer unequips.  objectmagic didn't have to be
                changed since extract_obj automatically does the work now. :)

8/31/94 JE      Fixed cityguard routine with a CAN_SEE check so that blinded
                guards no longer banzai people, and so that guards don't
                banzai invis people etc.  Spotted by Ken Cavness.

8/31/94 JE      Fixed do_reply to make sure the person you're replying to
                is still in the game before calling perform_tell.  Note, I
                think it still may be possible for your reply to go to
                someone else if the recipient logs out and someone else logs
                in.  In particular, this will break in a big way if I ever
                implement some scheme where it keeps a pool of char_data
                structures for reuse.

8/31/94 JE      CHA added to display when rerolling a character.

8/31/94 JE      Changed TOUNGE to TONGUE throughout.

8/31/94 JE      Made the '*' (ignore) case in zone reset tables (used for
                invalid vnums) set last_cmd = 0 for proper resetting.

8/31/94 JE      Enhanced (added?) NeXT compatibility with FOPEN_MAX, my_signal,
                and O_NDELAY.

8/31/94 JE      Changed boards back to listing lowest to highest since people
                seemed to hate it the other way.

8/31/94 JE      Added sanity checks to perform_move since king_welmar seems
                to cause crashes when he's moving on occassion, and I'd rather
                remove that area than try to debug it.

8/31/94 JE      Changed 'SEC' to 'RL_SEC' in structs.h to avoid conflicts
                with many OS's #defines of SEC

9/1/94  JE      Good God, is it September already?

9/1/94  JE      Changed list_skills to accumulate in a buffer instead of
                using send_to_char, and use page_string.  This system really
                sucks.  There should be a "page_to_char" command, or something.
                It shouldn't even require too much conceptual difference now
                that output buffers are limited!

9/1/94  JE      Added a 'sort_spells()' function and changed list_skills
                to use sorted spell list instead of arbitrarily ordered list.
                sort_spells() called once on boot from db.c.

9/1/94  JE      Finally finished making the background story paged.  Now that
                process_input and command_interpreter, etc., have been
                rewritten, all it took was changing it from SEND_TO_Q to
                page_string.  Whoo hoo!

9/1/94  JE      Jeff Fink suggested having perform_act do some run-time
                sanity checking in order to make it more robust.  Thus,
                I created the CHECK_NULL macro for it in comm.c.

9/1/94  JE      Made mobs hit you if you try to cast an offensive spell
                at them and fail.

9/1/94  JE      Completed line-by-line zone-parsing routines.  Instead of
                using scanf() to read from disk, Circle now uses fgets().
                This allows MUCH more robustness, more accurate and sensitive
                error-checking of zone files, both at boot-time and run-time.
                In addition, the error reporting now gives you a specific
                _line number_ in the zone file of the error. :)

9/2/94  JE      Made a 'qecho' command, combined with qsay in do_qcomm
                of act.comm.c.

9/2/94  JE      Updated the README file.

9/2/94  JE      Circle 3.00 beta patchlevel 3 released

                starting up again, ya know.)

9/19/94 JE      Changed lantern-handling in update_char_objects in handler.c;
                now gives warning one tick before the light expires (idea
                from Chris <ttl6u@fulton.seas.virginia.edu>) and correctly
                decrements world[ch->in_room].light as it should have from
                the very beginning.

9/19/94 JE      Changed the build_house parser in house.c to allow for
                a house which has more than one exit (i.e., only one of
                which is access-controlled) because people seem to want
                multi-room access-controlled areas.

9/19/94 JE      Fixed multi-room-shared-atrium bug in house_control_house,
                house.c (I haven't heard of this bug ever manifesting itself
                but looking at the code I realized the error.)


9/19/94 JE      Changed 'long' to 'time_t' where appropriate.

9/19/94 JE      Added graceful handling of missing playerfile in db.c

10/9/94 JE      Added charisma-to-25 code to do_restore (act.wizard.c)

-- Sanity break

2/20/95 JE      Added max length check to set_title in limits.c -- all
                title setting should go through this function

2/22/95 JE      Added check for null name in 'show player'

2/22/95 JE      included unistd.h in house.c, boards.c and objsave.c
                for unlink prototype

2/22/95 JE      Low-lev imms can no longer see invstart people above their
                level entering game

2/22/95 JE      Changed 'color' and 'syslog' to show current levels if typed
                without arguments, instead of help text.

2/22/95 JE      fixed castle by adding terminator to end of move string
                reported by Ed Mackey (emackey@BIX.com)

2/22/95 JE      If you try to return to your original body, and someone else
                has connected into it, disconnect them.  act.wizard.c,
                do_return().
                reported by Aaron Mills

2/22/95 JE      interpreter.c - changed the code to sense if a switched
                persona of yourself is connected when you log in.  Should
                make switch more stable.
                reported by Aaron Mills

2/22/95 JE      new timediff in comm.c to work on systems for which
                tv_sec and tv_usec are unsigned
                reported by Steven Serocki <ss@sirocco.cup.hp.com>

2/22/95 JE      change RLIMIT code for systems that don't have RLIMIT_INFINITY
                reported by Steven Serocki <ss@sirocco.cup.hp.com>

2/22/95 JE      changed title_type[4][35] to [NUM_CLASSES][LVL_IMPL + 1]
                throughout
                reported by Darel Cullen

2/22/95 JE      changed "his arm" to "$s arm" in act.obj.c
                reported by Chris Epler <cepler@ucsee.eecs.berkeley.edu>

2/22/95 JE      act.other.c, do_quit() -- kill off all sockets connected to
                the same player as the one who is trying to quit.  Helps to
                maintain sanity as well as prevent duping.
                duping reported by Chris Epler <cepler@ucsee.eecs.berkeley.edu>

2/22/95 JE      installed new version of Jeff Fink's shop.c code

2/22/95 JE      Patched bug in Jeff Fink's shop code reported by him
                patch send by Jeff Fink

2/22/95 JE      created player_specials structure for new players coming in
                after having been deleted.  Yet another example of a bug that
                could have been avoided completely if we'd been using C++.
                Reported by Jeff Fink

2/22/95 JE      Added code to support 'R' command in zone resets (remove
                obj from room).  Code sent by Jeff Fink.

2/22/95 JE      Changed plain 'stat' to make better assumptions about what
                you're trying to stat.
                Code sent by Jeff Fink

2/22/95 JE      Added go_gen_door code written by Jeff Fink to eliminate
                duplication of checks, etc. for open/close/lock/unlock/pick

2/22/95 JE      Fixed shop code -- changed keeper = 0 to keeper = me

2/22/95 JE      Added magic_alter_objs code submitted by Jeff Fink

2/22/95 JE      Added break statement to mag_damage, energy drain       
                Spotted by Jeff Fink

2/23/95 JE      Created 'random.c' as Circle's new, portable random number
                generator.

2/23/95 JE      Added 'POSIX_NONBLOCK_BROKEN' option to work around OSs
                such as AIX which don't implement POSIX nonblocking I/O
                correctly, causing the MUD to hang in places such as the
                Password: prompt.

2/23/95 JE      Added a case for sgi (IRIX) in utils.h OS-specific header
                section for cleaner compiles


-- Patchlevel 6

2/24/95 JE      Fixed asciiflag_conv in db.c for uppercase flags (typo,
                'a' instead of 'A').

2/24/95 JE      Added max_bad_pws to config.c.

2/24/95 JE      (logged retroactively) Added max_filesize to config.c to
                set max limit on size of bug, typo and idea files to prevent
                bombing

2/24/95 JE      Moved 'pfilepos' from descriptor_data to char_data where is
                belongs.  More logical, plus fixes the switch-into-a-PC-and
                save bug reported on rec.games.mud.diku by
                shruew@amiserv.xnet.com (Johnny Mnemonic).

2/24/95 JE      Similarly moved password from descriptor to character.

2/24/95 JE      Changed nonblock to OR-in O_NONBLOCK to the current flag
                bitvector of descriptors instead of setting directly.

2/24/95 JE      Changed 'last_tell' (used by reply) to use player ID number
                instead of a pointer to the character.  Much safer because
                I don't have to worry about pointer reuse, plus it'll still
                work if the person you're replying to logs out and back in
                again.

2/24/95 JE      Changed distribution-default of nameserver_is_slow to NO.

2/24/95 JE      Fixed src/util/showplay.c

2/24/95 JE      Added MAG_ALTER_OBJS to SPELL_INVISIBILITY in spell_parser.c

2/25/95 JE      Fixed PC/NPC checks in act.wizard.c, do_set.
                Reported by Eric Green and Stefan Wasilewski

2/25/95 JE      Fixed carried-by/worn-by reporting of objects
                act.wizard.c, do_stat_object.
                Reported by Eric Green and Stefan Wasilewski

2/25/95 JE      Deleted 'equipment status' from do_stat_obj in act.wizard.c
                --didn't seem particularly useful and took up valuable screen
                space

2/25/95 JE      do_wiznet, act.wizard.c, wiznet chops off first letter of
                message when levels are used.  Reported by Eric Green and
                Stefan Wasilewski

2/25/95 JE      do_ungroup, act.other.c, fixed so that disbanding a group
                doesn't un-charm charmed mobs following you.
                Reported by Eric Green and Stefan Wasilewski

2/25/95 JE      magic.c, changed so you can't sanct sancted mobs
                Reported by Eric Green and Stefan Wasilewski

2/25/95 JE      Brought in fixed world files from furry and corresponding
                castle.c and spec_assign.c for new specproc assignments

2/26/95 JE      Removed minor output display but on object statting, do_stat,
                act.wizard.c  Spotted by Eric Green.

2/26/95 JE      Added max string length checks in perform_subst(), comm.c
                Reported by Eric Green and Stefan Wasilewski.  Also added
                comments to the function.

2/26/95 JE      Similar length checks in perform_complex_alias, interpreter.c

2/26/95 JE      Made buffers MAX_INPUT_LENGTH size to handle very large output;
                tmp_name in interpreter.c, *_search in do_who and do_users
                in act.informative.c

2/26/95 JE      Rewrote most of do_group, act.other.c

2/26/95 JE      do_ungroup, act.other.c - disbanding a group also ungroups
		yourself.

2/27/95 JE      Added olc.c and olc.h.

2/28/95 JE	Added bank card specproc to spec_assign.c

2/28/95 JE      Updated FAQ and README-BETA

3/3/95	JE	Patchlevel 6 released
