In Dennis_V5, that is the kernel (and specifically conf.c, low.s, and mch.s as the most recently modified source files), on Mar 21 1975. The next newest files are dump, restor, and (kernel source) rkf.s and nami.c... but there's no associated object file or change to lib2. The latest objects in lib1 and lib2 (and therefore presumably the kernel) are: lib1: sysent.o and sys4.o (Nov 21 1974) / maybe this change is getpid? lib2: kl.o (Dec 2 1974)
