From abb14fe23c0a8adab6497d51e500160ce0c11a8f Mon Sep 17 00:00:00 2001 From: Chris Dent <cdent@anticdent.org> Date: Tue, 24 Sep 2019 12:22:07 +0100 Subject: [PATCH] Add train-prelude release note This is essentially a duplicate of the cycle highlights provided with the release, plus a warning about needing to upgrade to extracted placement in stein before the train upgrade. Few links are provided because the rest of the release notes are very short and will be presented adjacent to the prelude, and they have links.
