@mcop1 Why do you drop the Button? We are using it in serveral projects.

What was the motivation for this @Corepex?

[Corepex]

@aweichler and @NiklasBr the button component was a security issue in itself. We decided to remove the feature to prevent any security vulnerabilities in the future.

[NiklasBr]

Do you have any documentation about it in the migration notes and recommendations for achieving the same functionality with another feature?

Create your custom layout component, see https://pimcore.com/docs/pimcore/current/Development_Documentation/Extending_Pimcore/Bundle_Developers_Guide/Adding_Object_%20Layout_types.html

@Corepex maybe we can add that to upgrade notes
