 ### Changed
 
 - **BREAKING**: The class `Friendica\App` was completely refactored and marked as internal, work with `Friendica\AppHelper` instead.
+- **BREAKING**: The `contact_block_end` hook provides a HTML string instead of an array.
 - The `bin/composer.phar install` command no longer optimizes the autoloader file to avoid various problems when adding/removing classes in dev. Run `bin/composer.phar install -o` if you want autoloader optimization.
 - Downgrade shebang from `bin/bash` to `bin/sh` in `bin/console`.
