Nextcloud 11 main improvements

The Nextcloud project has become the largest and most active in its space and is backed by a healthy, growing and profitable company. Together, the project merged almost 1200 pull requests in core alone, bringing a wide range of enhancements to users.

This release introduces significant security improvements, attested by NCC Group, a global expert in cyber security and risk mitigation to “complement the existing security architecture” and “enhance the general standing of the security working environment.

New security capabilities include:

  • Support for cutting edge browser security features CSP 3.0 and Same-site Cookies
  • Support for Kerberos authentication and Two-factor Authentication providers based on Universal 2nd Factor and Time-based One-Time Password
  • Expanded brute force protection to all API access points
  • More secure Federation through use of SSL/TLS
  • Our new app store automatically checks apps and enforces signatures

Scalability is a prime concern among our large enterprise customers. This release decreases database load by up to 80% and improves response time by up to 60% for common server operations. Combined with multi-bucket Object Store support, improved handling of previews and Collabora Online speed improvements Nextcloud 11 enables scaling to greater numbers of users and files, decreases the server load and improves the user experience.

Nextcloud 11 introduces Apache Solr powered Full Text Search, enabling users to find words or phrases in text, pdf and common office documents on internal, external, shared and encrypted storage. The next generation Federation technology introduces a central lookup server, enabling Nextcloud users to find each other irrespective of the server their account resides on. The experimental Spreed app integrates secure, peer to peer audio and video chat in Nextcloud.

Read on for more details on these features.

Security

For Nextcloud 11, security has been a prime concern. Privacy and control over data mean little if security is not in order. Nextcloud 11 introduces a series of new security capabilities and hardening, delivering security following the latest industry standards and enabling administrators to opt in to further measures.

  • This release includes Two factor authentication support for Universal 2nd Factor (Yubikey and compatible) and Time-based One-Time Password (Google Authenticator and compatible)
  • Support for Kerberos authentication
  • Password confirmation for sensitive actions
  • HTTPS by default for federation
  • Password reset logic auto-invalidates after changing mail address
  • Improved brute force protection on more endpoints
  • CSP 3.0 protection and Same-site Cookies Support improvements
  • App specific tokens can be forbidden file system access
  • Our Collabora Online integration app has several security hardenings
  • Our new app store automatically checks apps and enforces signatures

NCC Group, a global expert in cyber security and risk mitigation, reviewed the addition of these features and noted they “enrich the security layers with minimum impact on the user” and are developed using industry standard security processes (assessed against ISO27001 clause 14 controls).

New app store

Given some security related incidents with the old app store like this and this, security of Nextcloud systems benefits from a move to our new app store on apps.nextcloud.com. The new app store integrates an automatic check on uploaded apps, ensuring a significant proportion of scam and spam attempts is blocked before even making it to the store. Vetted developers have to sign their app with a private key, signed in turn by the Nextcloud Code Signing Authority which ensures even a successful compromise of an app store account can not result in malicious apps being uploaded to user systems.

Find more info in our earlier blog about appstore improvements and a recent blog about app signing.

Performance and scalability improvements

Scalability and efficient operation are key capabilities sought after by system administrators. Nextcloud 11 introduces changes which result in decreased database load and faster execution of common operations known to cause significant load on large instances.

db-queries-per-propfind

Typical Nextcloud instances should benefit from up to 80% less database queries and 60% faster execution of checks for changes (“propfind“) as done by the Nextcloud clients. This operation is often accounting for over 95% of the load on big installations. With database usage often a major limiting factor in scaling up this should result in significant decreases in load and a subsequent increase in capacity for Nextcloud servers. Syncing small files also benefits with up to 60% faster transfer of small files.

speed-improvement-in-percent

To make Nextcloud systems with object storage more scalable, this release introduces a multi bucket object store. Not all s3/swift implementations like having multiple million objects in a bucket, so Nextcloud 11 will create a bucket per user, helping with storage performance on large installations.

Thanks to improvements in the integration with Collabora Online, startup time has been improved in Nextcloud 11 and users will now be able to enjoy their online office suite faster than ever!

Last but not least, large folders will load considerably faster while thumbnails are handled far more efficiently as well as now shared between users, saving significant resources on instances where many users share the same set of files.

You can read more details and an analysis of their impact in our blog on the performance improvements in Nextcloud 11.

Full Text Search

Nextcloud 11 introduces full text search with the optional Nextant search application. Using Apache Solr, Nextant indexes the content of:

  • User files
  • Shared files
  • Federated cloud shares
  • External storage
  • Server-side encrypted storage
  • Bookmarks

It recognizes plain text, rtf, pdf, jpeg & tiff, html, LibreOffice and Microsoft Office file formats. System administrators can opt to use a standalone Solr or use Solr as a Service for a more scalable solution. Learn more about full text search in Nextcloud 11 in our blog.

Next level of Federation

Federated Cloud Sharing enables users to share files between Nextcloud servers. Nextcloud 11 introduces an optional, global ‘address book’ to search for other Nextcloud users to share data with. In the personal settings, users can op to share certain data like country of residence or social media accounts which can be used by friends to identify them for file sharing.

Nextcloud will operate the lookup server and we are looking into distributing this task, creating a fully decentralized network.

You can learn more in Bjoern’s blog on Federation in Nextcloud 11.

Technology Preview of Spreed integration

Nextcloud 11 brings Spreed audio and video chat integrated in the user interface. The Spreed allows you to invite any of your friends and colleagues on your Nextcloud server for a call and also allows sending a public link to people who don’t have an account yet. Users will get a notification if they are receiving a call. Up to six users can join a conversation.
spreed-in-action
Spreed for Nextcloud 11 is still under heavy development and considered a technology preview. While the app is largely stable there are a lot of features we’d still like to add and cross-browser and cross-device compatibility improvements are a work in progress.

Read our blogs for more information about Spreed video calls in Nextcloud 11.

User interface and other improvements

Delivering a great user experience has always been a central goal for the Nextcloud team and this release makes significant strides in this area. File handling was improved with move actions for files and folders as well as a easy way to share the current folder and share files and folders by mail. Thanks to a database update, we can handle emoticons in file names without breaking their synchronization on servers using MySQL.

The updater has seen a rewrite with a new approach aiming for reliability and stand alone functionality so a break anywhere in Nextcloud won’t impact the updater.

The Contacts and Calendar apps also have seen a number of improvements, most notably by introducing public sharing links in the Calendar and improved contacts import in the Contacts app.

How to get it

The massive number of improvements are a true testament to the progress the Nextcloud project is making. Dozens of users have helped us test this release (some earning a t-shirt in the process – and hundreds contributed with translations, code and in other ways.

The packages for Nextcloud 11 are building and will be available in the next hour or so.

If you would like to update, you can do so by downloading the zip file on our download page and following the manual upgrade instructions or wait for 2-3 weeks until we make the new release available in the Nextcloud Updater app. If you prefer to update now already using the easy to use Updater app, you can set the release channel to beta this will give you Nextcloud 11 final. Be sure to set it back to stable after the upgrade is done!

If you encounter any issues, we recommend to look for help on our forums and, if it is a bug, report it.

  1. Sounds like a controlled roll out. Get the enthusiasts on board first to check if any unfound critical issues are found, then push it to standard users.

  2. Hi,

    Sorry for the confusion! We usually only offer a new major release some weeks after it is out on the updater. So if you want to use that to upgrade you have to wait until we 'turn it on' and then you get notified and can update.

    You can of course manually update already.

    But some people prefer to use the updater app (like myself) because it is super easy and fast. So - we put Nextcloud 11 on the 'beta' channel. If you set your version to beta and reload the page, you get an upgrade to Nextcloud 11 (once it is on the mirrors - that will still take some minutes). After upgrading you set your updater back to 'stable' and that's what you get from then on :wink:

  3. @grzegor Lots of people have different understandings and priosations for various topics. Also you cant implement everything that is nice to have in a timeframe of a few months. If this topic is super important for you either get a support contract or create a pull request.

  4. Sweet Godzilla.

    :heart_eyes:

    If I can help, count me in.

    :heart_eyes:

    You guys are phenomenal.

  5. I'm happy to take that compliment on behalf of the people who ACTUALLY do the work :stuck_out_tongue:

    /me hides now for the bananas thrown at him

  6. Here's another for you: I just upped to 11 manually and damn it is fast.

  7. Just upgraded my home NC 10 to 11: How bloody boring! 30 seconds of clicking and a 130GB NC jumps to the right (by one).

    I resigned myself to this non distro integrated application a while back - I'm a sysadmin with 20 years experience of one or two systems and that is not the way "we" do things cough - I have not been disappointed yet. This particular NC started off life as an OC 7 on Centos and is now on Xenial.

    For this update I didn't bother with a snapshot first (I did check the backups though)

    Good work devs n co. Love it - seriously boring upgrade. I'll test the new functionality and move my other instances later.

    Calendar on Nextcloud 11 major bug spams a users contacts while importing a calendar from google

    This is going to really piss off folks like me who saw this project featured on Linux Action Show and decided to import data into a new install...

    They specifically touted this project as a replacement for Google Apps and Dropbox!

    Well it seems like less marketing promo press releases and more devs testing especially the functions users use when adopting nextcloud is in order.

    Major bozo move guys...

  9. About 40% of the users now should have received a notification for Nextcloud 11.0.1. Every day this week, we add another 10% so by Sunday, everyone should be notified :wink:

    Of course, if a big issue surfaces, we'll slow down again.

    Just get it today :wink: It's on progress ... thank you
