Look at feefilter BIP 133 (https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki#backward-compatibility) or sendheaders BIP130 (https://github.com/bitcoin/bips/blob/master/bip-0130.mediawiki#backward-compatibility) Isn't it the same there? Once BIP151 is implemented, it would make sense to bump the protocol version, but this needs to be done once this has been implemented/deployed.

Any peer can send you any type of message anytime. Why would your implementation how you threat unknown messages be different for messages specified in BIP151? --WigGl22UoseNw9COWWPrDDRnFeG8K91Hc-- --ViPaN93HIHR1HHdhg8BejSJdcshOoO36Q Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEMu5cTD+hXMrbRqvlKdS8tkFvU+wFAlihhVwACgkQKdS8tkFv U+wkhw/9GdgXTyrZOv3xsdjrj96UBPNPT+ouj1yxMpjKU9BmSirYZ22UMFga6Afk c1sptolfYp3oOH5Z47JR1Tk8r/ArkjqPpWGDqlXmapJg5qfdvx7GgDVxfJCTyTJY dr0/AW+sFTiO/tvFGFqUANtgkVXiT0eFqkzXjtZNg/xDUkyywDMSZzcVF/2SDcih l73TyJk8ZDtR+FtaG0/pU7G/wf34Z6ECg7A/cpBh3ySBmSRZB2Z6thY4TbOnZ8wu xj3aE8UYmagEE5hKvsnTszW+9slkLJZ34MwDujPogd1L0lmMxaEty4nBLKdy531h b4ciHJsGO1NkeO8bLqWwxeFdEFPtop4q4w5L/p/vHX2tJRxgJ8TxBmLUOedr+BKq sfjEji7IY00t0/Oj0OQb2TVffU8Yq+L+TPO6a+sg4IWYY0U5g5kiw7H0sehsORcv QvYiviiR26/58qOMe5FhawYhXtPQMLabVhUGrnGXTYtEpRh3KopNDlMpUUKaVRvj vNsChHDWN37eEpx1OJLQaNBaCot3eRku8ngqSJzSL6xyYOClMjFx7ROjV8pAgpEg XnNhWBjzC2BQF+cWsy1LjDV4GLyT6wqEaGvARae0YiMAtZAyzl69ALFtvvbBrz2i O6m/ocY64FuVko+ExkFadBjZeQLZlxpbI/nMvz/DHv5w+pxEOmw= =i0O/ -----END PGP SIGNATURE----- --ViPaN93HIHR1HHdhg8BejSJdcshOoO36Q--
