[Breaking change]: Media Picker (legacy) (Umbraco.MediaPicker2) to be deprecated from version 11 and removed in version 14

[lassefredslund]

Description

The "old" Media Picker (legacy) will not be implemented with the new backoffice that currently is expected to be introduced in version 14.

Version

Umbraco 14

Previous behavior

You could choose among the Media Picker (legacy) and its successor the Media Picker (v3).

New behavior

Use the Media Picker v3.

Type of breaking change

• Binary incompatible: Existing binaries may encounter a breaking change in behavior, such as failure to load/execute or different run-time behavior.
• Source incompatible: Source code may encounter a breaking change in behavior when targeting the new runtime/component/SDK, such as compile errors or different run-time behavior.

Reason for change

With the new backoffice we want to streamline both the developer- and editor experience while we invest our effort in property editors that we foresee usable on a long term.

Recommended action

Avoid using the Media Picker (legacy).

Is there any easy way on a v10 LTS site to see if Umbraco.MediaPicker2 is in-use anywhere? One of the things we're struggling with on these v14 LTS removals is evaluating what's in use and how to migrate everything. For example, someone suggested USync Migrations to move things from Grid/Nested Content. Now this MediaPicker v2 stuff (potentially) needs attention and other smaller things like 404 using Xpath needs to get sorted out. Ideally Umbraco would have some sort of migration tooling (maybe even building off of uSync Migrations) to make this easier for big sites with tons of content where it's a monumental task to re-do all of the content (again--we just did this in rebuilding from v7 to v10 LTS this summer and these items being removed weren't marked as deprecated unfortunately.)

I can recommend the plugin "diplo godmode". You can easily check where certain datatypes are used wih that.
