The last Nextcloud release, Version 29, Dubbed Hub 8, was with vast improvements in performances, but not very significant, compared to version 28 Before it.
However, this new release of Nextcloud 30 Be connected with Nextcloud Hub 9 - Nextcloud
Packs a ton of improvements both in performance, smaller footprint, Code improvements, and for Integrators like myself, A Much better Integrations Management.
This Release Version nextcloud/server: 
Nextcloud server, a safe home for all your data (github.com)
Surely packs a ton of Improevements for everyone, from general users, to developers, as well as Integrators.
In Nethserver, we ussually wait untill .01 release however, in this case, we are having abit of a situation with nethserver 8.
We are currently running version 28 of Nextcloud, we would need an Update that upgrades nextcloud to version 29, and Subsequently, Getting to the current Release version of 30, or 30.01 when it finally releases.
This issue should be fixed with version 8.2 of Nethserver, which should resolve Upgrades between multiple versions of an App on the software center.
I am one of the Users who is really looking forward to nextcloud version 30
The biggest additions for me are, Workflows, as well as ability to tun tables into programatic workflow applications. that can be shared
As an @education_team member, and in the process of impelmenting a college management system for a local Technical institute in kenya, One of the unctions i believe would be a great addition to our impelemntation is, the one below
Ability to request for Files, Based on workflows for submited forms.
I understand the impending challenges on getting nextcloud 30 into NS8 at the moment, however, @stephdl as mentione din the chats, i would love your help to see if we could get a working testing case of NC30 on NS8, for fresh installation, as we wait for official release
