Od vzniku forku uplynulo p\u016fl roku a spole\u010dnost Apple neobnovila pr\u00e1ci na CUPS. <\/p>\n

V reakci na dotaz Michaela Sweeta spole\u010dnost Apple potvrdila, \u017ee nem\u00e1 z\u00e1jem o dal\u0161\u00ed rozvoj funkcionality CUPS a hodl\u00e1 se omezit na \u00fadr\u017ebu k\u00f3dov\u00e9 z\u00e1kladny pro macOS, v\u010detn\u011b p\u0159en\u00e1\u0161en\u00ed oprav z fork\u016f od OpenPrinting.

Zm\u011bny se pl\u00e1nuj\u00ed zahrnout do vyd\u00e1n\u00ed CUPS 2.4, ve kter\u00e9m se tak\u00e9 o\u010dek\u00e1v\u00e1 zaveden\u00ed kompatibility s AirPrint\/Mopria, p\u0159id\u00e1n\u00ed podpory autentizace OAuth 2.0\/OpenID, podpora pkg-config, zlep\u0161en\u00ed podpory TLS a X.509, podpora atribut\u016f \u201ejob-sheets-col\u201c a \u201emedia-col\u201c, a vy\u0159azen\u00ed cups-config a autentizace p\u0159es Kerberos. <\/p>\n
