Deprecation Tracking

Deprecations Tracking is similar to Exception Tracking and logs all PHP errors with the E_DEPRECATED and E_USER_DEPRECATED error type. Deprecations are aggregated based on the location they occur at so that you can easily spot code that needs to be adapted for futures upgrades.

By default deprecations tracking is disabled and needs to be set in the PHP INI configuration of your project with this directive:

You then need to restart your PHP process (FPM, Apache) and deprecations will be tracked from there on.
