[RFC PATCH 2/4] doc: gitbreaking-changes: replace msg-ids with URLs

From: kristofferhaugsbakk@fastmail.com <kristofferhaugsbakk@fastmail.com>
Date: Sep 28, 2026, 10:41 UTC
Message-ID: <URLs_not_just_msg_ids.d1e@m5gid.xyz>
In-Reply-To: <CV_gitbrchanges7_please.d1c@m5gid.xyz>

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

This document has used msg-ids to reference emails since its inception.[1] This makes the text a bit more terse, and is perhaps also convenient for people who can use msg-ids to link to messages in their inbox. But we should consider how convenient this is for people in general, now that this is a more public-facing page (see previous commit). And I suspect that most people will be forced to paste the msg-id according to the described URL template:

    https://lore.kernel.org/git/$message_id/

Let’s instead replace all of the msg-ids with complete links. That way everyone can jump right to the discussions.

† 1: 57ec9254 (docs: introduce document to announce breaking changes, 2024-06-14)

Note that we have to URL encode two msg-ids:

     CAKvOHKAFXQwt4D8yUCCkf_TQL79mYaJ=KAKhtpDNTvHJFuX1NA@mail.gmail.com
     CA+EOSBncr=4a4d8n9xS4FNehyebpmX8JiUwCsXD47EQDE+DiUQ@mail.gmail.com

Lore can handle them just fine, but asciidoctor(1) cannot.
