From 2cd01a1df2afc16ada1ce8479fbf888a803270ea Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Thu, 30 Jan 2020 10:40:01 +0000 Subject: Add NEWS entry about 64-bit time_t syscall use on 32-bit targets This internal change ideally should not affect the public API or ABI, but there is a widespread use of seccomp sandboxes, even on 32-bit targets, that don't handle new Linux syscall usage well, so it's worth mentioning in the NEWS.
