Collabora 2 Upgrade and limits

HI, will docker automatically upgrade to latest collabora, because when I run: docker pull collabora/code:latest it say I am on latest version, but how can I know that I am on Collabora 2.0 ?

latest: Pulling from collabora/code
Digest: sha256:3baab22efefd34d7a152690f01ed89b1c512f0ec03acbe0ec27654b2f6eedc83
Status: Image is up to date for collabora/code:latest

Also I am noticing that there is some sort of limit of 20 connections and 10 documents, what is that ?
