Nextcloud Hub offers the most advanced on-premises collaboration platform complete with audio/video chat, real-time collaborative document editing, mail, calendar and contact management.

Below we will go into more detail on what’s new.


When logging into Nextcloud you are immediately greeted by Workspaces. With Workspaces you can bring context to your folders, adding notes and even todo lists and links to files on top. This is great to coordinate with your team, making sure everyone knows what a particular folder is for. The best part: Workspaces are also available on mobile!

Nextcloud Files also introduces a new, more responsive sidebar with a number of improvements. It shows other users who have access to a file, even if it is nested deep in a shared folder, and proposes a secure password you can use for a password protected share.

Accepting incoming shares is now possible, and in the sharing settings you can choose to transfer ownership of a folder to another user.

Last but not least, Nextcloud Files introduces file locking, to prevent conflicts with colleagues who are trying to edit the same files as you do. Of course with the office documents and text files in which you take notes, you can conveniently edit with others in real time, but sometimes you have to download a file to make local changes and upload it again. Simply choose ‘lock file’ in the 3-dot menu and the file will be locked until you unlock it. You can see who locked other files, and of course ping them on Talk or in the comments if you want to know why!


Flow makes it easy to automate repetitive, boring tasks. For example, let’s say you are a sales person and send quotes as PDF. You set up a flow that turns documents into a PDF when you add a tag, say ‘to-pdf’. Or, say you want to put a message in your teams’ chat room when a partner uploads files in a specific folder.

Apps can include flow elements like triggers or actions, and separate flow apps can be build. If you’re interested in building for flow, check for documentation!

Flow with analyticsFlow with analytics

The first third party app that has flow integration is the Data Analytics app by developer Marcel ‘Rello’ Scherello. This application is designed to turn data into reports, tracking and analyzing data which can be imported through an API. Data Analytics provides modular datasources, a realtime or storage backend and flexibile visualization. Its flow integration allows it to monitor files for updates or act on other events on Nextcloud.

Editing office documents is a basic feature users expect from a online collaboration solution. Nextcloud is proud to be the first on-premises content collaboration platform to feature out-of-the-box, Microsoft Office compatible document editing through ONLYOFFICE.

With its latest release also comes improved integration, with our sidebar available so you can easily share, comment or look at older versions of the document you are working on.

ONLYOFFICE’s community edition is installed by default on a new Nextcloud installation. For users who already run Nextcloud, installing it requires just one click – like all Nextcloud apps! No need for docker containers, web server configuration or other complications.


A brand new image gallery makes finding, browsing and sharing your images easier than ever before.

Photos shows you a timeline of your photos. In the left sidebar you can find your favorites and tagged photos. You can also find pictures in all the albums you have access to, including pictures people shared with you and external storage.

We should also mention Locations which uses the Maps app. This shows where pictures are taken on the world map!

Calendar 2.0 with Talk integration

Nextcloud Hub, introduces a much refined interface rewrite of our popular Calendar app. This major release brings many user interface improvements as well as some basic feature enhancements like advanced recurrence, a busy-view for meeting planning and resource booking and more. Calendar 2.0 now has integrated Talk rooms, allowing users to add a chat and video call to a meeting.

Mail 1.0 recognizes itineraries!

Nextcloud Hub marks the introduction of Nextcloud Mail 1.0. This release introduces the ability toe extract travel information from emails. Mails from airlines or train companies will be accompanied with an easy overview of your travel plans and the trip can be easily added to the Calendar.

The 1.0 release marks a large improvement for Mail, with full support for rich text mails, improved acount handling, signatures and more. Version 1.1 is already scheduled for early February and will introduce improved caching and threaded mail view.


Talk 18 features a rewritten user interface with a focus on improving the chat experience of users. A few highlights:

  • 📫 message delivery notifications & delayed messages so users can keep typing messages while they get delivered in the background
  • 🔍 a new interaction with the conversations sidebar, adding a search on top and a dialog to create a new conversation
  • 👥 Integration with Circles allowing users to use these custom groups in Talk
  • 🗣 Replies using quotes
  • 🤩 Big emoji’s when they are the only thing in a message
  • 🔔 New message notification for background tabs

To prevent accidental clicks, Talk will warn you during a call that navigating away from the page will end the call.

Besides the direct improvements to Talk it is worth noting the benefits from integration with Flow and the Calendar.

As always – this has been a big release, with many improvements! And it would not have been possible without the help of our amazing community. Thank you all!!!


I’m really curious to see :
HOW OnlyOffice work inside Nextcloud without having a docker image and what about the ram consumption and performances.
If it’s as good as docker, then great job :+1: i’m really happy of it.

Awesome new features and improvements!
I am so amazed! Good job guys!
Somebody is definitely updating his prod server today :smiley:

Wow! :slight_smile:
This is surprising me the most and I’m very thankful that having Onlyoffice will be much easier now.


Do you see how? I read “… For users who already run Nextcloud, installing it requires just one click – like all Nextcloud apps…”
But where to click :shushing_face:


This makes me really happy!! :partying_face: hats off to the Nextcloud team!! (of course also for all the other nice additions :slight_smile: )

sorry, found it here. :face_with_monocle:
Community Document Server


Taken from your link :
The community document server is designed to make it easy to get OnlyOffice running in a Nextcloud instance without the need to setup an external document server, the community document server does not support all features of the official OnlyOffice document server and does not provide the same performance and scalability.

So it’s useless for me. I know how to install Docker onlyoffice/DocumentServer so i will have better performances.

But it’s truly a good start for people who can’t install the docker edition of OnlyOffice.

That’s good news. Do you plan on still supporting Collabora Online ?

Looks good. When is a ETA to release it in the Web Updater?

what is ETA?

Estimated time of availability/arrival

I think as always: in the next week, rolling release.

Between tomorrow and 15 days if nothing that breaks code is found.

The way v18 will spread on the updater is aleatory.

I can have the notification in 2 days and you in 4.

So what are the RAM requirements for running nextcloud including the Community Document Server app? The same as for OnlyOffice Community server (so 6GB+ RAM) or is it a trimmed OnlyOffice that will run on my 2GB RAM vServer?

The system requirements for OO are bogus. The Docker image of the regular Document server needs about 1 gigabyte of RAM although it might spike with many users. Have not stress-tested it much.

Just for information, downloadsize for Community Document Server ist 290MB and i need with my testserver with low networkconnection this:

to prevent cURL error 28: Operation timed out (CURLE_OPERATION_TIMEDOUT: Operation timeout. The specified time-out period was reached according to the conditions)


The App Community Document Server wont start.

I see this in the logfile:
