Is there a way to know which add-ons are creating messages in the Developer Log in the EE control panel or is it basically a process of elimination?
Example messages:
A third-party add-on is calling $this->load->library('security'), which is deprecated as the CI_Security class has been moved to Core, so it is always loaded.
The system has detected an add-on that is using outdated code that may stop working or cause issues with the system. Deprecated function login_form() called in on line 0.
