This is also why the Windows 10 May 2020 update is v2004 instead of v2003 to avoid issues with old software thinking it is running on Windows Server 2003. [1]
My manager at work came across this version number on a document properties screen (possibly in Word?), thinking it referred to the version of software the document was written in. We bullshitted a bit about how we're still iterating on 16-yo documents, until I googled and found that it was a new MS version.
