The following files are patches intended for Angband 2.9.2, which do as follows:

292-heavy-prompt.pat :

Adds an option for a prompt before picking up items heavy enough to slow the player.

292-pits-feel.pat :

Changes the way level feelings are affected by pits to be dependant on the type of pit/nest
and the depth.

292-feeling.pat :

Changes the way the level feeling delay is calculated, so time in the town has no effect 
on it. In other words, if you go down to the dungeon, spend some time in there, go back to
the town, and return to the dungeon, the appearance of the level feeling will depend on
the last level you were in in the dungeon, and not on the town.

292-artifact-mem.pat :

Adds artifact memory. If you *identify* an artifact in one game, all subsequent games from
the same savefile will know the artifact's abilities (unless randarts are used). Note that,
while this patch does not break savefiles, wierd things may happen if a character is taken
back and forth between a version that supports this and one that does not.
