Supervisor does not offer update in ui

Since the supervisor-2021.04.3 version, the supervisor does not offer me to update to the most current version (2021.05.1 is already there), it indicates that version 2021.04.3 is the latest.

if I check the log it only appears as a warning, I do not know if it is related.

05-21-09 16:40:06 WARNING (MainThread) [supervisor.addons.validate] Add-on config ‘startup’ with ‘before’ is deprecated. Please report this to the maintainer of Coffee Maker

screenshots are attached

2021.4.3 is the latest supervisor version. 2021.5 is still in dev and hasn’t been ‘built’.
