Nextcloud Hub 26: What's New in Winter and Spring?

Nextcloud Hub 26 is the current release generation of the open-source collaboration platform and consists of the Winter and Spring releases. For admins, teams, and self-hosting users, one question matters most: what is actually new, and which changes are worth it in day-to-day use?

The short answer: Nextcloud Hub 26 mainly improves performance, digital sovereignty, and collaboration. Alongside technical foundations like ADA and expanded migration features, it also introduces visible changes such as Euro-Office, Nextcloud Governance, and a lighter interface.

Nextcloud uses the name "Hub" for its product generations. In Nextcloud Hub 26, two major releases belong together:

• Hub 26 Winter with a focus on performance, migration, and cross-server collaboration
• Hub 26 Spring with a focus on office choice, governance, UX, and more productivity updates

Instead of seeing it as one long feature list, it makes more sense to view Hub 26 as an expansion of the existing platform: Nextcloud wants to make teams less dependent on closed SaaS stacks while also making operations more attractive for self-hosting and organizations with compliance requirements.

A core part of Nextcloud Hub 26 Winter is the new ADA architecture (Accelerated Direct Access). It is a deeper rework of data access so that apps and services can reach files and metadata faster.

In practice, this means:

• faster response times in heavily used instances
• less load during everyday operations
• benefits for Photos, Talk, AI features, and clients
• a better foundation for larger teams and more complex setups

For users, this may not be the flashiest headline, but in day-to-day work it is often one of the most important improvements. Especially with self-hosted installations running several active apps, it is not just the feature list that matters, but how smoothly the platform performs under load.

Another major point in Nextcloud Hub 26 is improved migration. The migration app, installed by default, now supports not only files but also Mail, Contacts, Calendars, Tables, and Deck data.

That is especially relevant for two scenarios:

1. you move from an existing Nextcloud instance to new infrastructure
2. you want to become less dependent on a previous provider or setup

This matters directly for ZAP-Hosting readers: if you start small on a VPS and later move to a larger Cloud Server or Root Server, it helps a lot when data and workspaces can be transferred more easily.

Hub 26 also expands federation. The goal is collaboration between different Nextcloud instances without forcing everyone into the same central system.

Cross-server collaboration was expanded in areas such as:

• Deck for project planning
• Calendars for cross-team scheduling
• Teams and communication across organizational boundaries

That fits the broader Nextcloud idea: collaboration without losing control of data, identities, and hosting locations.

One of the most visible changes in Nextcloud Hub 26 Spring is Euro-Office. Alongside the familiar Collabora-based solution, there is now a second office option directly inside the Nextcloud ecosystem.

Why does that matter?

• more choice for office integration
• a focus on European digital sovereignty
• strong compatibility with common office workflows
• an extra option for teams with priorities different from Collabora

For many organizations, that flexibility is exactly the point. Some prioritize classic document compatibility, others open standards or tighter integration with the rest of the Nextcloud stack. Nextcloud Hub 26 tries not to force a single path here.

With Nextcloud Governance, Hub 26 is also aimed more clearly at larger organizations, public authorities, and regulated environments. These are setups where retention, classification, access rights, and auditability are not optional.

According to the sources, key points include:

• a better overview of compliance-related tasks
• Sensitivity Labels for sensitive data
• Legal Hold for legally relevant files
• rules for the lifecycle and deletion of data
• more transparency in administrative and audit processes

Not every home server needs these functions. But for companies and public-sector environments, this is one area where Nextcloud Hub 26 feels much more mature than many simple file or groupware solutions.

Alongside the major platform topics, Nextcloud Hub 26 Spring also refreshes the interface. The new design focuses on fewer distractions, clearer navigation, and a waffle-style app launcher.

There are also improvements to the Nextcloud Assistant, especially in how it works with search and context from multiple apps. That makes Hub 26 more attractive for teams that want to bring files, chats, calendars, and tasks together in one interface.

Nextcloud Hub 26 is especially interesting for:

• self-hosting users who want more performance and better migration paths
• teams working across multiple instances or organizations
• companies and public authorities that care about privacy, sovereignty, and compliance
• admins who want more flexibility between office options

If you mostly use Nextcloud as private file storage, not every new feature will matter equally. But if you use Office, calendars, chat, projects, or multiple users productively, Hub 26 offers much more than a cosmetic update.

For self-hosting, Nextcloud Hub 26 is especially interesting because it improves both the technical base and the product features at the same time. That is often more valuable than isolated marketing features.

What you should watch before updating:

Before any major update, always back up your data, database, and configuration.

Third-party apps in particular can delay an upgrade if they have not yet been adapted to the new major version.

A setup that only syncs files has different requirements from a team using Office editing, Talk, Whiteboard, or AI features. For smaller setups, a VPS or Cloud Server is often enough. For larger teams, many concurrent users, or additional services, a Root Server can be the better choice.

Several official sources point out that Nextcloud AIO makes the upgrade path much easier. If you want as little manual maintenance as possible, that is an important option to keep in mind.
