As this wasn't documented in the release notes, we're looking into it. The few poses that have been changed may have been unintentional. Thanks for flagging!
Is there a chance someone just forgot to add them to the release notes? Most look like improvements over the previous ones.
My theory is that they were merged incorrectly. So, they were in development (either planned for a future release or shelved) but they accidentally got dropped into this update. It happens occasionally in game development due to all the internal builds. Just my theory, though. We're looking into if this was just left off the notes or unintended.
