AFAICT we have a far wider pool of people testing -next than we do testing the stable -rcs at the minute, there's more people trying to *use* stables and finding issues but that's not quite the same thing and I suspect much of the plain testing is going to be qualification for release so it'd be hard to get people to substitute mainline. --vX7k9uSYvsG5RQ71 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmZ0P8cACgkQJNaLcl1U h9Boagf/cngV0gEMswycSNPrpeqcuWfnV0At9XYkCCWFFOPoH5FNdKyZ9tF9B2zk b1dF5zCEn+0LZZQSLWgwZB/vL4yOBS9EoMyCe71+u9ml4oe2udwGQMS9K4L6gh0b sK7ZfZBUVUHV2k0K8DpQqLLfWQSNDWUyXzsg4qap0+5NDqryJC6MfZbqmhzf1gIn fZ5qoL3VJmC97Bn698zxcp7rFTrxtT8UEdXNlLlb/Yzg9Jr5TU21DxbAusqH8Pb5 HRoMeFqvIey9+x1trHz2Nt5rbRGIkp9my9Cx8XWxf7Vko/8n4ZLMyaXybXMMLQ0U 3ZDoyMaG3FSV1/Pxp41EjVMdzOiHXA== =/Xgt -----END PGP SIGNATURE----- --vX7k9uSYvsG5RQ71--
