Category:Unfinished and Prerelease Content

“Unfinished and prerelease content” refers to certain mutations, changes to existing mutations, and other features that are enabled by turning on the in-game option that says Enable unfinished and prerelease content. Save compatibility is not preserved across changes to this option, meaning turning it on or off can cause existing saves to fail to load.

Deprecation

According to Jason Grinblat, one of the lead devs of Caves of Qud:

pack rat is very deprecated at this point. "prerelease content" is a misleading name

As such, it may not be safe to assume that Pack Rat or other features enabled by the option will remain in the game and supported.
