Regain control over your time with Nextcloud Hub 8

Hi Nextcloud community! 👋

as we are announcing Nextcloud Hub 8 here at the Nextcloud Enterprise Day in Munich, our customers and partners are presenting their own and unique use of Nextcloud. Tens of millions of users trust Nextcloud to protect their data.

These include private users, running their own Nextcloud, or using a hosted solution from the likes of América Móvil or Deutsche Telekom. Businesses, keeping data on their own servers or hosting at one of our official partners. And the public sector, with universities, cities, governments and international organizations like Amnesty International using Nextcloud to stay safe. They maintain their own servers or host with partners like Bechtle that offers tender-free Nextcloud for the public sector in Germany.

We build Nextcloud to give you control over your data. In terms of who has access, but also what. Our world is digital, and AI is digging through all its data. It can use that for good – create fun meme, summarize your mails or help medical research. But should it operate heavy machinery or be used in the courts or HR departments?

While society finds its way through these dystopian questions, we make sure you have control. Different options, plus transparency over what AI does and how helps you make informed choices. That aligns with our core values of transparency, community and collaboration.

This release introduces many abilities specifically for the public sector. Some of those are AI related, developed together with public sector partners like the German state of Schleswig-Holstein, presenting here today. Others tick off important requirements like our new European accessibility certification, improved scalability or federated chat. But all of these benefit every Nextcloud user, at home, in an office or working in a cafe somewhere!

This release is faster, scales further, and gives you more control over your data than ever before. Whether you watch our release video or read the blog, we are looking forward to your feedback, and, as always, hope Nextcloud serve(r)s you well!

Greetings,
Jos & the Nextcloud team

Take Nextcloud Hub 8 for a test drive

Explore Nextcloud Hub 8 and try all of the core apps to unveil the potential of a collaboration platform trusted by tens of millions of users across the globe.

Try Hub 8

Ask Assistant about your own assets 🕵️

Hub 8 enables Nextcloud Assistant’s new context awareness features. One of them is Context Chat, a smart chat bot that can access your data and answer questions about your documentation, contracts, papers, reports or anything else. You can manually define the scope and even limit it to a specific folder or file for more precision.

Here you can enter your prompt.

You can optionally choose what documents should be used

And here are the results!`

And it’s not limited to Files: we developed an API that allows Assistant to look into Mail, Calendar, Talk, Deck and other apps to fetch info about important meetings, tasks received via emails and chats, and any other data from those apps. Over the coming weeks and months, we are going to gradually implement the Context Chat API across the Hub ecosystem, making Context Chat ever smarter.

Texts written your way with Context Write 📝

Context Write is another new feature of Nextcloud Assistant powered by context awareness. It can derive context from existing files to convey their unique tone, wording, and even structure to create new texts with the data you provide. Tell the Assistant about your working experience and give it a nice CV file, and it will create a custom CV for you. Share meeting notes and ask it to write a formal report similar to your reference – done!

Generate Mail replies and automate events in Calendar 💌

With Hub 8, we add more Assistant features to Groupware tools. Get reply suggestions based on your conversation history in Mail. Create Calendar events from emails without leaving the Mail app, automatically generate event titles and descriptions, and even an agenda. Go ahead – take an extra coffee break!

Chat summaries in Talk 🍡

Summarization of team meetings and spontaneous brainstorms in Talk chats makes it easy to get a refresher on previous discussions. The new AI Talk bot can recap your conversations, describe the discussed topics and define tasks based on chat activity. Give it a preferred time to deliver the summary, and it will send it in the chat when scheduled.

Prompt history and even more tools in Assistant 🛠️

Assistant 2.0 gives you even more control. Access prompt history when you need to reuse your past prompts, and ask the Assistant to stop unfinished tasks if no longer needed. We also gave even more functionality to the Assistant, adding built-in image generation and speech to text features.

Synchronous tasks in Text ⏩

Text now supports running Nextcloud Assistant tasks in a synchronous way. If your AI provider is able to return the results fast enough, the Assistant can deliver them in the window right away. If it takes longer, you can choose to run the job on the background and get notified once it’s done.

Nextcloud AI-as-a-Service

For these AI features to work smoothly, you will need some serious hardware. This unfortunately will not be a fun experience on your Raspberry Pi. But! Luckily, a number of businesses have started to provide AI-as-a-Service, running various open source models that Nextcloud supports in a way that you can connect to remotely. While this is great, unfortunately nearly all these companies are American-based, with a few in China. If you live in the USA, that is of course perfect – the data stays in your jurisdiction, and you have a choice of local providers. But for our users in Europe, this is less than ideal. The US jurisdiction unfortunately treats the data of European users with less than ideal respect for privacy, in no small part thanks to the CLOUD act signed into law by the former US president Donald Trump.

we have been working closely with several major European hosting companies including IONOS, OVHcloud and plusserver to integrate their upcoming AI-as-a-Service solutions. This will make them available to Nextcloud customers and users who wish to take advantage of the advanced AI functionalities in Nextcloud Hub but don’t wish to host AI services themselves.

OVHcloud is thrilled to collaborate with Nextcloud in delivering state-of-the-art Digital Sovereign AI solutions to our customers. We are aligned with Nextcloud’s commitment to offering secure, privacy-conscious AI functionalities that safeguard training data and adhere strictly to GDPR regulations. We are excited to announce that this integration will become available in Q2 2024, marking a significant milestone in our journey towards responsible AI innovation.

Germain Masse, AI Product Marketing Manager at OVHCloud

We are proud to offer Nextcloud customers a solution that complies with European data protection regulations. Reliable, trustworthy, and local AI services will be key to protecting their digital sovereignty for both the public and private sectors in Europe.

IONOS

Edit meeting notes in a Talk chat while video conferencing, scroll through a project Deck board on a Collectives page, or add a whole interactive calendar to your planning file in Text — you name it. With interactive widgets in Hub, you can quite literally embed one app into another.

Hub 8 supports interactive widgets for files, folders, Deck boards and calendars. You can paste widgets in Talk chats, Collectives pages, Text files, and Deck card descriptions.

View and edit files 👀

Using widgets, you and other users with access can view the linked file contents and make edits without leaving the app. To prevent accidental edits, file widgets in Talk open in view-only mode by default.

Link Forms to sheets 🔗

Link forms to spreadsheets to automatically submit collected data to ODS, XLSX, or CSV files. Re-export, create new sheet copies and edit the linked sheets to add more columns with comments, statuses and any other data you need.

Manage users you follow when collaborating

It’s now easier to follow and unfollow users in your documents, spreadsheets and presentations. The currently followed user is directly visible, so you always know whom you are following. Unfollowing became more convenient too: just click on the list to resume independent browsing.

More features in Office

More than just Tables

Let’s talk about Tables, a versatile data processing app in the Hub ecosystem that elevates your workflow management. In Hub 8, we included improvements in Tables navigation and data imports, as well as introduce a complete new mechanic: no-code apps based on Tables.

Build custom Tables apps 🎛️

Need a custom app in your Hub to manage a process, centrally access project data, or build a dedicated knowledge base? Now you can create custom Hub apps based on Tables, streamlining management of individual teams, projects, or processes. Aggregate and combine existing tables and views and add them as a new application to the menu bar for quick access.

Navigate your tables in a pinch 🔦

All tables are accessible from a single list that you can filter to find the most relevant items quickly. Add tables to favorites to keep them on top of the list at all times, or archive unused tables to clean your space without losing old data.

With Nextcloud Tables, we’re definitely getting to a point where we can replace traditional specialized software, (German: Fachverfahren), by storing the data structures in Nextcloud.

Sven Thomson, CIO Schleswig-Holstein

New ways to import data 📊

Import tables from external files using the upload feature or from the right click menu from the Files app. We improved file parsing to automatically detect more items from CSV and spreadsheet files, such as dates, percentage, currency and decimals.

Transfer ownership with ease 🤝

Now users can change the owners of the tables themselves, making it easier to manage tasks without admin permissions. The setting is available in the Edit window.

Files, your own 📂

Getting lost in a massive amount of shared documents? Enjoy a clean space for yourself with the Personal files section to find all of your own files and folders. Accessible from the web and Nextcloud clients, your documents, drafts, photos, invoices and other items are always close at hand. Plus, we added file recommendations to help you get to recently edited files faster.

More features in Files

The Smaug-72B model is a significant advancement in open-source language model development. It is a powerful large-scale language model that excels in reasoning and math tasks.

Build apps for Nextcloud! 🧑‍💻

Whether you want to create mobile apps that connect to Nextcloud, integrate independent apps in Hub, or build dedicated apps, we’ve got you covered! You can build applications in any programming language, make use of our complete API documentation, and follow ready tutorials to get inspired.

Speaking of which, we are constantly extending our library of app tutorials, and this time we added two awesome new guides: a hello world app tutorial and a guide to using Github Codespaces as a developer environment.

New app ecosystem features 🌏

The app ecosystem update gives new liberties to app developers. With declarative syntax, now you can define custom setting screens for admins and end users. Opening opportunities for deeper integration with Nextcloud, we made it possible to inject a full user interface in Nextcloud. To aid the contributing developers in localization efforts, we also let you get help from our translator community using Transifex.

More in integrations and apps

• OpenID Connect user backend: improved stability
• OpenID Connect user backend: improved user migration
• OpenID Connect user backend: enabled user count
• OpenID Connect user backend: make the app work for non-standard providers
• OpenID Connect user backend: enabled custom endpoints URLS and custom attributes

• External app ecosystem: added injecting a page UI
• External app ecosystem: added support for AI apps
• Improved app routing mechanism

VFS support in macOS app

With Hub 8, we are releasing a new client for macOS that has support for the Virtual File System (VFS). The new sync engine adds more agility to file browsing, presenting all of the files available on the server without downloading them and taking extra disk space. These files will only be downloaded when you need to interact with them.

Easier app updates on Windows

Great news for our Windows users: new versions of the desktop client can now be installed without user intervention in most cases, making the update process smooth without disrupting your work.

MDM in the Android app

Enterprise customers will be glad to read that the Android app now has Mobile Device Management (MDM) integrated. The feature allows you to manage the mobile devices connected to your Nextcloud and therefore greatly improve security controls.

Other features in clients

• Nextcloud Assistant in clients
• Support for client certificates
• Hardcoded proxy on Android
• Design improvements in iOS app

New level of performance

Organizations big and small rely on Nextcloud to supercharge their collaboration. That’s why we take performance and stability very seriously. Efficient software is not only about getting things done fast and serving a large base of users, it is also about reducing energy consumption and running on diverse infrastructures without losing efficiency.

With this release, we started working on the Database Sharding which lets you split Nextcloud database into several smaller databases and to distribute it among a few smaller servers. The basis for Database Sharding is already here, and we are planning to work on it moving forward to bring the opportunity to our users.

Another noteworthy improvement is in continuous work on the Read-After-Write behavior. Current architecture requires synchronous replication, which reduces the number of database cluster nodes to 4. In the future, we will support an unlimited number of Read nodes that are using asynchronous replication.

These efforts in boosting Nextcloud performance will allow us to accommodate up to 10x more users within a single cluster, moving the scalability of Nextcloud to a whole new level.

This, and numerous smaller but meaningful updates in the frontend make the Nextcloud experience much smoother, not only tackling the challenges of the large setups but also improving the performance for every user. After all, it’s all about giving you more time, achieved with scrutiny of every detail.

Ready to get the feel of the new Hub?

From continuous work on AI features and interface optimization, to various new shortcuts between apps and performance improvements — we tried to make Hub 8 worth your while. This is a result of the meticulous work of our growing team of engineers and designers, our contributors, and the whole of Nextcloud and its community.

Thank you for reading and sticking to the end! We took some of your time with this hefty blog, but we promise to give some of it back with Hub 8! 😉
