Move to gender-neutral language.

If you lose the Magic Purse, it gets recreated on a future level.

Removed old flush and terse options.

New option to choose type of run (doorstop).

 - can't start game with best armor
 - artifacts are more dangerous
 - fewer blessed items
 - more likely to be summoned to a throne room


July 2019
---------

When choosing which monsters to use in a game, make sure to
include monsters summoned by other monsters we include.

Workaround: doctor daemon still dies sometimes, so restore will
recreate it.

Fix: ring of sustain ability (etc.) don't blow up when enchanted.

Can enter wizard mode when restoring a game (for debugging).

Improve accuracy of id_monster().

Make genocide scroll more rare.

If there's no food on the first two levels, there will be on the third.

Bumping into a wall also searches for secret doors.

Shops now have shopkeepers.

Chance of hitting high level opponents improved from none to slim.
This fixes a problem where players with very good armor would never be hit,
making the deepest dungeon levels too easy.

Use wgetch() for user input and let curses deal with escape sequences
(eg. arrow keys), as this is more portable.

Removed some quaint old code (shell escapes, load average checks,
wizard password file).

If urogue can't access a central score file, put it in the users's home
directory instead.

Stolen artifacts sometimes reappear if thief disappears, and
occasionally scavengers drop stuff when they disappear.

Scorefile, saved characters and save/restore now work on Windows.

Monsters don't get a saving throw against blessed sticks/wands
or the Sceptre of Might.

Fix: save/restore of doctor daemon sometimes failed.

Make backspace work when typing filenames and options.

Show blessed/cursed status of food and rings when itemizing pack
when game ends.

Fix: reset keyboard state when restore of saved game fails.

Swapped 'c' and 'C' commands, as per 1.0.7.

rip.c: show what happened just before you died.

Gain ability potions are more rare, as per 1.0.7.

When running, <shift><dir> acts like <ctrl><dir> used to
(run ends before you run into things).
Also, <ctrl><dir> runs now alternate searching and moving.

In genocide(), truncate long names in list so they don't wrap.
In genocide(), press 'b' to back up and show list again,
press 'q' or ESC to exit.

If there are fewer than NLEVMONS*100 monsters, we'll run out of new
monsters before we run out of levels.  So space them out a bit more.
Conversely, if there are too many monsters, we show new monsters more
often or we'll never see them all.

Can 'm'ove through monsters when phasing.

Try harder to find a place for dropped items.

Can't fight when diseased or infested ('f' and 'F' commands).

Once activated, the Silmaril maps new levels automatically.

Less chance of being sent to a throne room when you go up a level.

Backport monster flags from 1.0.3, and bumped the
t_flags and m_flags arrays from 10 and 4 to 16 each.
This lets new monsters have new abilities and lets us
add new flags (i.e. CLASSIC).

Now includes most monsters from 1.0.3 with command-line options
to choose which ones to use:
  -mc: classic monsters from 1.0.2
  -mr: a random selection of monsters
  -ma: all 300+ monsters
  -mm: classic monsters plus lots of random extras
The default is classic monsters plus a few random extras.

Defined a few new constants in rogue.h so array sizes aren't hard
coded in multiple places (NT_FLAGS, NM_FLAGS, NMSGS, NFINGERS).

Show blind/diseased/infest etc. state in status bar.

Implement
ISLARGE, ISSMALL, ISFAST, CANFLY, CANTRAMPLE, CANSWIM, DRAINBRAIN, DRAINWISDOM, NOMETAL


May 2019
--------

'F' command now fights a group of monsters.  I.e., when the monster you're
fighting dies, it picks another and keeps fighting as long as there's a
monster in reach.

Fewer interruptions (and fewer messages) when fighting ('f' and 'F' commands).  
In particular, you don't get tired of fighting as quickly, and you don't stop
fighting when zapped, unless the bolt causes damage.

Nymphs can no longer curse protected items.

Once activated, the Phial lights up new levels automatically.

Magic mapping shows secret doors as '&'.  This works around a bug where
magic mapping released monsters from treasure rooms.

Scoreboard now shows which entry is current run, if you made it into the
top 10.

Magic and prayer points slowly regenerate when not hungry or hurt.

'x' command to rest (same as '.', but left-handed)
'g' command to move right (same as 'l', but left-handed)

'f/F' commands avoid quartermaster and monsters that divide when hit.

If a 'F'ight ends quickly because there are no more monsters in reach,
wait a bit in case others come in range (if not hurt or hungry).

Don't stop 'F'ighting when hit by a second monster.

Enchanted armor offers some protection from magical attacks.

Fixed calculation of how much mithril protects against magic.

Create a unique ID for each game.  Users can restart saved games over and
over (by copying the save file), but each game only appears in the
scorefile once.

Warn player each turn while suffocating.

Increase chance of finding secret doors (less typing).

Scroll of genocide shows which monsters are already gone
(e.g. due to earlier scroll of genocide).

'd'rop multiple food at once, like arrows and rocks.

Fights end when we recover from being held, paralized, etc. instead
of at the start (to reduce the number of annoying messages).

Fix: half the time find_slot was called with arguments in the wrong order.

Removed wizard scorefile commands from rip.c, and replaced
it with program to delete lines from score file (scorefile.c).


April 2019
----------

Fix: save/restore favorite fruit, number of items in pack and bag.

Check that save file is complete, because sometimes it isn't (due
to gcc address sanitizer)

Add support for arrow keys (via ANSI escape sequences, not curses, sigh).

Protected crystaline armor doesn't shatter.

Stop 'f'ighting when hit by a second monster (used to be when attacked).

Save/restore which monsters are available (e.g. not genocided).

Fixed a use-after-free error in chase(), using position after monster dies.
Fixed a use-after-free error in runners(). If the next monster in the list
dies (eg. after being zapped by the current monster) we reset the pointer
to the next monster (nitem). Initialize t_quiet in new_monster().
Thanks valgrind.


March 2019
----------

Backported and enhanced save/restore code from urogue 1.0.7.  Also daemon
code as it's needed for save/restore.  I.e., ported save.c, state.c and
daemon.c from 1.0.7, with changes to many other files.

Made evil sorceress more vulnerable (change AC from -16 to -10 as in 1.0.7).

When enchanting weapons, keep hit and damage closer together.

When game ends, use space to page through final info, rather
than alternating space and return.

When fighting, reduce number of "bounce" messages from zapped bolts.
Also, quit fighting when fainting from hunger.

Cleanup unused code in pack.c.

Plugged some memory leaks.  E.g., in new_level() monsters from old level
were freed, but the contents of their packs were not.


February 2019
-------------

Added ',' command to pick up an object


January 2019
------------

Artifacts:

Trying to invoke an artifact, and failing, may cause minor or major harm.
 - reduced the chance of minor bad effects
 - removed major bad effects

Parasites:

Originally, parasitic infestation could only be cured by a cure disease
scroll.  Now infestations clear up on their own (like diseases, but more
slowly).

Fighting:

When using 'f' or 'F' commands, don't ask for a direction if there's only
one monster in reach and visible (to reduce typing and wrist strain).


November 2018
-------------

Electrification:

When you read a scroll of electrification, nearby monsters are damaged for 
several turns.  This is done by iterating through the monster list.  But if
one dies, it gets removed from the list and the 'next' pointer becomes
invalid, leading to a segmentation fault.  So we save it in tmp_item,
temporarily.

Wizard mode:

Originally wizard mode required typing a null character as a command-line
argument to urogue (and typing a password), but that's too hard, so you can
now use 'urogue -w -w' instead.


Earlier
-------

 - pack.c, weapons.c, sticks.c
   (delay cleanup of items until we're finished with them,
    i.e. after they've been thrown or dropped)

 - monsters.c
   initialize and use flags correctly

 - save.c
   Save and restore don't work in modern operating systems.
   They used a hack (save would dump all the program's memory to disk;
   restore would overwrite the running image (code and data) with the
   old image).

 - init.c
   Write strings to buffers instead of pointers.
