[4.1 Beta 4] XF2.x user_content_change_init code event listener does not update username in database while VW is enabled (Impacts XF and addons)
With VaultWiki 4.1 Beta 4 b004 enabled, XenForo
is not updating usernames in content related tables, such as xf_post, xf_news_feed plus any applicable addon tables. The service
does update the username column (\XF\Service\User\ContentChange) for any applicable tables while VaultWiki is disabled.
I first noticed odd behaviour in my own custom addon which on my test site ended up with stale usernames even though that it implements the
user_content_change_init code event listener.
On the front end, it is particularly noticeable for entries in "Latest activity" (What's new) where stale usernames may be encountered, e.g. for XFMG:
ACL reacted to OldUsername's media
Hopefully this is an easy fix that can be addressed for this release (in current or new build)

. I had planned to upgrade my public site today or tomorrow, prior to discovering the stale username issue.
