# Adopting 4.11 Mechanisms and APIs

This section describes changes that are required if you are trying to change your 4.10 plug-in to adopt the 4.11 mechanisms and APIs.

1. PDE feature `org.eclipse.pde` no longer includes the Error Log view.

## 1. PDE Feature `org.eclipse.pde` no Longer Includes the Error Log View

What is affected: Clients including PDE feature `org.eclipse.pde` to include the Error Log view.

Description: We migrated the `org.eclipse.ui.views.log` bundle from PDE feature `org.eclipse.pde` to Platform feature `org.eclipse.platform`. The ID of the Error Log view has not been changed.

Action required: Clients should:

- Consider removing `org.eclipse.pde` feature from products if it was included to get the Error Log view.

- Consider adding plug-in `org.eclipse.ui.views.log` to a private feature or include feature `org.eclipse.platform` which now contains the Error Log view.

- Consider removing `org.eclipse.ui.views.log` from private features if feature `org.eclipse.platform` is already included.

All those changes are backward-compatible. So you can apply them on a project using 4.10 as target-platform, and this would work on both 4.10 and 4.11.
