I also have always advocated longer support for APIs/ABIs but many develope= rs who work on cleanups prefer shorter periods which is understandable too Personally i would also favour if APIs/ABIs are only removed when keeping t= hem causes work. Often old API/ABI just needs a simple wraper around new API th= at has no dependancy on anything else than the new API working as documented. In other cases where there is risk that API/ABI might break in ways not rea= dily detectable, quick removial makes sense though thx [...] --=20 Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Concerning the gods, I have no means of knowing whether they exist or not or of what sort they may be, because of the obscurity of the subject, and the brevity of human life -- Protagoras --9NKq1Ol8H4UpZ5M6 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABEIAB0WIQSf8hKLFH72cwut8TNhHseHBAsPqwUCZbeeSgAKCRBhHseHBAsP q77EAJwIaYW00mbiK2Y30RwW+t/eXwpAWgCfX+fFpxmoS1X+Re5RqCup6hvsrgc= =2JJB -----END PGP SIGNATURE----- --9NKq1Ol8H4UpZ5M6-- --===============3358852229403726301== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe". --===============3358852229403726301==--
