Another who got significant changes.Poor halflings in 1E; they had a pretty terrible time. If it wasn’t the bulette it was the ankheg.
Even before taking into account campaign specific variants like Kender on Krynn, cannibal elder race on Dark Sun, and dinosaur riders of Eberron, they have changed a bunch over time.
First they were Hobbits who quickly lost their name to infringement claims. They were sometimes tubby, sometimes slim. Sometimes round eared sometimes pointy eared. Their actual height varied significantly across editions. They were often Hobbitish fantasy English farmers but 4th turned them into river nomads more like Romani. Sometimes they are good at hiding and ranged weapons, some editions they are inherently lucky.
