 Stinking clouds created by reading a scroll no longer use a predefined rhombus shape, and instead expand from their origin point to fit the terrain. This makes them even more dangerous in closed spaces.

-Poison clouds are introduced with the scroll of stinking cloud in [[NetHack 3.3.0]].
+Poison clouds are introduced with the scroll of stinking cloud in [[NetHack 3.3.0]]. From this version to [[NetHack 3.4.3]], including some variants based on those versions, poison clouds do not yet have their own glyph, rays of poison do not leave behind poison clouds, and the Plane of Fire does not emit poison clouds. Additionally, poison clouds are subject to some [[Bugs in NetHack 3.4.3|now-fixed bugs]]:
 * Monsters affected by stinking clouds always get angry at you, even if you did not create the cloud. This is bug C341-1 and was declared fixed in January 2004; while 3.4.3 mostly fixes the bug, it can still occur if loading a bones file from an older game in the 3.4 series.
 * The display of stinking clouds on the map may be incorrect when wearing [[The Eyes of the Overworld]]. This is bug C343-213 and was fixed on September 21, 2006.
-* The [[invulnerability]] granted from a successful [[prayer]] does not prevent damage from poison clouds. This is bug #H2645 according to the commit that fixed it ({{commit|0add5217}}), and the fix was made in 2012.
