new maestro after a weird issue.

Found a sticker in the box that i should update to 2.03 before using.
Is there any difference with the current boards and the older one I had?

RRF 2.04 is the current release, which was recently released (probably since that label was printed): https://github.com/dc42/RepRapFirmware/releases/tag/2.04
Update to that. 2.03 was the release before that, released June 2019.

If you've got machines on older versions of the firmware, it may be worth updating. My view is that if they work, fine, leave them alone. If you want/need the new features, update, but be aware of the firmware changes and the changes you may need to make to your config.g: https://github.com/dc42/RepRapFirmware/blob/dev/WHATS_NEW.md

there was a timing bug before 2.03 that would cause layer shifts on long prints.
