Unfortunately the latest update has no update notes, so we can't tell you what was changed in it.
The last update that we have patch notes for is:
Current Version: v258.81
* Fixed tamed Griffin not being ride-able without saddle (there is no Griffin saddle
* Fixed Ragnarok spawn counts being too low
* Fixed Ragnarok high-level Cave Direbears being tameable
* Reorganized more Action Wheel options
Lets hope ARK stops updating soon as this amount of updates the last week has been ridiculous
