From 91085f308f49791c84c4af5934a18854733c58f7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Thu, 24 Jul 2025 08:53:19 +0200 Subject: [PATCH] NEWS: add description for DHCPv6 SIP feature Also move the description of IPv4DuplicateAddressDetectionTimeoutSec= to the section about systemd-networkd. The change of the timeout doesn't have to be described as "incompatible". It's more of a bugfix, the previous timeout was just strangely large and hopefully nobody relied on this detail of implementation. Also, reword to say that MPLSRouting= just controls enablement, nothing more. --- NEWS | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/NEWS b/NEWS index 288a3e2cd7..c35d38c99b 100644 --- a/NEWS +++ b/NEWS @@ -98,11 +98,6 @@ CHANGES WITH 258 in spe: * The D-Bus method org.freedesktop.systemd1.StartAuxiliaryScope() has been removed, which was deprecated since v257. - * systemd-networkd now supports configuring the timeout for IPv4 - Duplicate Address Detection via a new setting - IPv4DuplicateAddressDetectionTimeoutSec=.
