Papermerge Version 2.1

Hi,

I am using the linuxserver/papermerge image running on a synology NAS.
I noticed papermerge-core is running the 2.1.0 version, which has some additional advantages like split view to manage documents more easily.

Are the improvements sometime implemented in the linuxserver/papermerge version?
Or is this version not used anymore?

Thanks for any hints.
