The release train is off to a flying start in 2021. First up is the next minor release for the CMS, Umbraco 8.11. This release wraps up all the fantastic contributions from Hacktoberfest, along with some fixes and a new feature. We’d love your help in testing out the release candidate, take it for a spin and let us know if you find anything.


To help you provide us with feedback, I’ve gathered an overview of some of the items that you can help test for this RC. We have run internal testing and are very happy with the current state of the build - but extra polishing and testing is always helpful. So if you have time to help - or just find yourself super curious, feel free to dive into the 8.11. RC today. 

What’s in Umbraco 8.11?

Unattended Installs

Adds the ability to install Umbraco without having to click through the step-by-step installer. This can now be done by adding a bit of configuration and booting up a fresh install.

To enable unattended installs you need to:

  1. Set the correct umbraco version in web.config
  2. You need to have an Umbraco database connection string configured 
  3. Umbraco.Core.RuntimeState.InstallUnattended in app settings set to true. 

When you boot the site we'll check if the database is empty (has no tables) and if it is, the database schema and default data will be created.

You will not be able to login to Umbraco since no password has been set for the default user, you either need to have an external login provider configured or set the password programmatically.

This currently only affects fresh installs but support for unattended upgrades will be added in an upcoming version.

Remove all items for Multinode Treepicker (MNTP)

A new property action has been added for the MNTP property editor. This allows editors to remove all picked items in one go.

8.11 MNTP Remove All Items

We look to get this added for other pickers in a future release. 

Updated NPoco version

NPoco, which is a dependency in Umbraco CMS, has been updated from version 3.9.4 to 4.0.2. There shouldn’t be any breaking changes with this upgrade but if you are using NPoco we’d appreciate feedback if you encounter any issues.

… And much more

The release candidate is chock full of great fixes and improvements. Many of them from this year's Hackotoberfest. Along with the features described above you’ll also find another round of awesome accessibility improvements from the A11Y Accessibility Team (if you don’t know them check out this blog post). 

Massive HIGH FIVE YOU ROCK to all contributors and the Core Collaborators team for keeping track of it all.

You can find the full list of features and fixes on the 8.11 download page.

Breaking Changes

The breaking change in 8.11 relates to Unattended Installs. The app setting Umbraco.Core.RuntimeState.InstallEmptyDatabase that used to default to false is now obsolete and no longer used at all. Since this was a non-documented configuration we don't think this will affect anyone.

How to test

First, you need to make a new Umbraco installation from 8.11RC (links below) or upgrade an existing project, both scenarios can provide valuable feedback.

If you find things in the RC that are not working, we’d be grateful for feedback on the Github issue tracker. You’re welcome to add comments to the features and fixes listed under 8.11 release or submit new bug reports (click New Issue and select Bug Report), please prefix the issue with 8.11RC:.

As mentioned previously, the RC is feature complete, so we’re not going to add additional features but will, of course, fix bugs that prevent a stable release.
