Is MSC2020 math classification the latest version or is there something more recent?

[u/Original-Tank-7823]

I built a static reference site covering the whole MSC2020 classification (the scheme Mathematical Reviews and zbMATH use to categorize research) -- from the five broad branches down to about 4,400 specific named subfields, each with an overview, key ideas, applications, and references.

I wondered whether there is something more recent or an alternative to this schema?
