I see it is currently in v2.2.10-4:
So maybe you're looking for a v2.2.9-???
You could install the downgrade package from the AUR and try using it.
There is a certain risk of breaking something due to the dependencies.
If it is really important you can try, and in case of issues, you can update again (in the worst case you can restore a snapshot if your networking will not work at all to update).
