Transfer Wyndham points to Southwest Airlines?
 

Wyndham no longer appears to list Southwest Airlines as an airline partner to transfer points to at https://www.wyndhamhotels.com/wyndha.../travel-points

Is this a recent change? I'd really like to transfer Wyndham points to Southwest and I'm wondering if it's still possible somehow...

WyndhamRewards is not listed at the Southwest website either:

https://www.southwest.com/html/rapid...tel/index.html

so I don't see how it would be possible to do such a transfer.

Oh, a quick Google search found the answer to your "how recent" question, and to me 4 years is not recent at all:
