The maintainer:release-notes command no longer lists Contributors.

git clone --branch '1.4.x' https://git.drupalcode.org/project/single_content_sync.git
cd single_content_sync
drupalorg mrn 1.4.2 1.4.3 -f md

Resulting output:

Yes, the same thing for me.
Also, they disappeared from the list of issues too, previously there was something like this:

#3388157 by Murz, j.cowher: Handful of bug fixes

I've debugged it a bit, seems this is because now the commit message is created by GitLab, and it misses the user names.

Here is the code to collect user names:

drupalorg-cli/src/Cli/Command/Maintainer/ReleaseNotes.php

Lines 299 to 319 in ea547b2

	// Anything between by and ':' is a comma-separated list of usernames.
	$value = preg_replace_callback(
	'/by ([^:]+):/S',
	function (array $matches) use ($format): string {
	$out = [];
	// Separate the different usernames.
	foreach (explode(',', $matches[1]) as $user) {
	$user = trim($user);
	if (!isset($this->users[$user])) {
	$this->users[$user] = 1;
	} else {
	$this->users[$user]++;
	}
	$out[] = $this->formatUsername($user, $format);
	}
	return 'by ' . implode(', ', $out) . ':';
	},
	$value

And it expects usernames listed in the commit message. So, no idea for now on how to fix this.

The commit message is created from the MR title, so to restore this feature seems we should manually list all issue contributors in the MR title like this:

Issue #NNN by user1, user2, user3: Issue title

But seems there are no automation implemented for this, I raised a question in Slack about this: https://drupal.slack.com/archives/CGKLP028K/p1706086503684919
