Kev tso tawm ntawm GNU Autoconf 2.72 pob tau raug luam tawm, uas muab cov txheej txheem ntawm M4 macros rau kev tsim cov ntawv pib teeb tsa rau kev tsim cov ntawv thov ntawm ntau yam Unix-zoo li tshuab (raws li cov qauv npaj, "configure" tsab ntawv yog tsim).
Tus tshiab version ntxiv kev txhawb nqa rau yav tom ntej tus qauv C hom lus - C23, kev tshaj tawm ntawm cov ntawv kawg uas xav tau rau xyoo tom ntej. Kev them nyiaj yug tau raug txiav rau C compilers siv ua ntej-C89 (ANSI C) hom lus sib txawv uas txhawb nqa tsuas yog cov qub K&R (Kernighan thiab Ritchie) style function declaration syntax, uas tsis tau txais kev txhawb nqa nyob rau hauv cov qauv yav tom ntej.
Tam sim no nws xav tau tsawg kawg GNU M4 version 1.4.8 (GNU M4 1.4.16 pom zoo). Yam tsawg kawg Perl 5.10 yuav tsum tsim kom muaj qee yam ntawm Autoconf cov khoom siv los tsim Autoconf nws tus kheej, tab sis Perl 4 txaus los tsim cov ntaub ntawv configure.ac thiab M5.6 macros.
Tsis tas li ntawd, qhov kev tso tawm tshiab siv cov kev kuaj xyuas kom tso cai rau cov neeg tsim kho software kom ntseeg tau tias lub kaw lus txhawb nqa hom time_t, uas tsis cuam tshuam rau xyoo 2038 teeb meem (Lub Ib Hlis 19, 2038, lub sijhawm epochal lub sijhawm teev los ntawm 32-ntsis time_t hom yuav overflow). Ntxiv "--enable-year2038" kev xaiv thiab AC_SYS_YEAR2038 macro los pab kom siv 64-ntsis time_t hom ntawm 32-ntsis tshuab. Tsis tas li ntxiv yog AC_SYS_YEAR2038_RECOMMENDED macro, uas ua rau muaj qhov yuam kev thaum siv 32-ntsis time_t hom.
