-From 617d4b9140b35f4f74def98b87a69a84943a33de Mon Sep 17 00:00:00 2001
-From: Igor Raits <igor.raits@gmail.com>
-Date: Mon, 28 Dec 2020 12:44:52 +0100
-Subject: [PATCH] Always require upper-bound dependency with ~ sign
-
-Proper fix is quite complex and given we do not package pre-release
-versions very often (and esp. not multiple versions of them), this is
-good enough (not nice though).
