* Iron bars can now be normal dungeon dressing. Before, they had only been seen in very few instances in Quest levels.
In 3.6.7, they could also appear in front of the 1-tile closets on the north/south faces of random rooms (specifically, the ones that would normally be locked and contain a scroll of teleportation). 5.0.0 adds iron bars to certain Gehennom levels.
* Monkeys in minetown can now try to steal items from you (those may have been in a previous version)
That's also been a thing for a rather long time.
* player monster corpses can generate on traps
3.6.7 had generic elf/dwarf/orc/gnome/human corpses spawning on traps, but 5.0.0 changed it so human corpses almost always spawn with a specific role - I played a few games last night on nethack.alt.org, and one of them found an archaeologist corpse on the first level of the Mines.
