Both issues concern Pyboard D firmware on the downloads page, but they describe distinct gaps. #5101 reports that Pyboard D firmware is absent entirely from the downloads page. #6062 is a narrower follow-on request: assuming firmware is now listed, it asks for threading-enabled builds specifically (as exist for Pyboard 1.x). The problems are adjacent but not the same — #5101 is about presence, #6062 is about a specific build variant. #6062 likely arose after #5101 was at least partially addressed.
Suggested action
Keep both open. Confirm whether #5101 has been resolved (Pyboard D firmware now listed). If so, close #5101 as resolved and treat #6062 as a standalone feature request for threading-enabled Pyboard D builds.
