Written by Rune Strand

The release candidate for Umbraco 8.14 is out sporting, among other things, a brand new Media Picker. We’d love your help in getting the release tested and ensuring it is ready for prime time - so don’t hesitate to take the latest version for a spin and let us know what you think 🙌


To help you test and provide 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 8.14. RC today.

What’s in Umbraco 8.14?

New Media Picker

You might be asking yourself, why do we need a new Media Picker? Well, using Media Items is a big part of creating and maintaining content in Umbraco and it’s been a while since the UX was last updated. This new version of the Media Picker includes several new features that we think will be really helpful to both developers and editors such as limiting what Media Types can be picked and how many, allow specific file extensions and you have the ability to create image crops locally.

It all comes with new and improved configuration options and Property Value Converters to make it easy to work within templates. You also find multiple new default Media Types and you can of course extend these and/or create new ones to suit your needs.

Last but not least, the UI/UX of the Media Picker has been completely redesigned to provide a better preview of picked images and a superior cropping experience.

You can find all the details in the new documentation for the Media Picker. Give it a try and let us know if you find any issues

Improved validation error handling

Being able to save an item before it’s finished can be really useful. This has been possible to a certain extent but if the item contained mandatory properties it would result in alerts. Furthermore, it wasn’t clear that the item was actually saved and there were cases, depending on the Data Type, that would not let you save at all.

With Umbraco 8.14 the validation messages have been updated to show as warnings instead of alerts (yellow as opposed to red notifications), which is a much nicer experience. 

Umbraco 8.14 Better Validation On Save

The Save button will also show a ✔ when the item has been saved and finally it should be possible to save all mandatory properties, allowing you to come back to your work. The notifications will still show as red alerts if you try to publish empty mandatory properties. 

The aim of changes is to provide a better (and less stressful) editing experience with a clearer indication of what has happened. 

See the original issue for more details.

Single item mode for the Block List Editor

The Block List editor has also received an update to the UX with an improved way of handling lists where only a single block type is allowed. It will now skip the Block Catalogue, which was unnecessary with only when type and allow for much faster content creation.

Try it out by only allowing a single Block Type on a Block List editor and add some content. Notice that the paste feature has been moved from the catalog to the Add button when in single item mode, this ensures you’re still able to paste in copied items.

See the the original issue for more details.

Validation bug 🐛

A bug regarding validation in Nested Content was reported a while back and we’ve received a lot of help investigating the issue. It essentially made the editor crash when some properties were left empty on Save (e.g Media Picker).

This has been addressed in 8.14 and we‘d love for you to test it out and help ensure it’s working as intended. See the full details on the bug and how to reproduce in the original issue.

Updated dependencies
