Changes in 1.1 r2:

# Debuggers no longer appear in internet cafes.

# Seijik and Zeius do not move around unless they are hostile.

# Gelatinous cubes will not engulf and digest Zeius. Gelatinous cubes will
not eat your artifact if they pick it up. Gelatinous cubes will not eat Zeius.
(N.B. It is still possible to lose your artifact by being overzealous with
a wand, or by leaving it lying around to get eaten.)

# Wands disintegrate things less often.

# Peaceful creatures will not usually attack your pet unless a pet attacks
them first or there is nothing else to do.
