	 * self::EXT ('ext') for the PHP extensions required,
	 * self::WP ('wp') for the minimal WordPress version required,
	 * self::WPFORMS ('wpforms') for the minimal WPForms version required,

	 * self::ADDON ('addon') for the minimal addon version required,
	 * self::ADDON_VERSION_CONSTANT ('addon_version_constant') for the addon version constant.
	 * self::PRIORITY ('priority') for the priority of the current requirements.
	 *
	 * 'php' value can be string like '5.6' or an array like 'php' => [ 'version' => '7.2', compare => '=' ].
	 * 'ext' value can be string like 'curl' or an array like 'ext' => [ 'curl', 'mbstring' ].
	 * 'wp' value can be string like '5.5' or an array like 'wp' => [ 'version' => '6.4', compare => '=' ].
	 * 'wpforms' value can be string like '1.8.2' or an array like 'wpforms' => [ 'version' => '1.7.5', compare => '=' ].
	 *   When 'wpforms' value is '{WPFORMS_VERSION}', it is not checked and should be used for development.
	 * 'license' value can be string like 'elite, agency, ultimate', an array like 'license' => [ 'elite', 'agency', 'ultimate' ].
	 *    When 'license' value is an empty like null, false, [], it is not checked.
	 * 'addon' value can be string like '2.0.1' or an array like 'addon' => [ 'version' => '2.0.1', 'compare' => '<=' ].
	 * 'addon_version_constant' must be a string like 'WPFORMS_ACTIVECAMPAIGN_VERSION'.
	 * 'priority' must be an integer like 20. By default, it is 10.
	 *
	 * By default, 'compare' is '>='.
	 *
	 * Default addon version constant is formed from addon directory name like this:
	 * wpforms-activecampaign -> WPFORMS_ACTIVECAMPAIGN_VERSION.
	 *
	 * Requirements can be specified here or in the addon as a parameter of wpforms_requirements().
	 * The priorities from lower to higher (if PRIORITY is not set or equal):
	 * 1. Default parameters from $this->defaults.
	 * 2. Current array $this->requirements.
	 * 3. Parameter of wpforms_requirements() call in the addon.
	 * Settings with a higher priority overwrite lower priority settings.
	 *
	 * Minimal required version of WPForms should be specified in the addons.
	 * Minimal required version of addons should be specified here, in $this->requirements array.
	 *
	 * We do not plan to restrict the lower addon version so far.
	 * However, if in the future we may need to do so,
	 * we should add to the addon-related requirement array the line like
	 * self::ADDON => '1.x.x' or
	 * self::ADDON => '{WPFORMS_ACTIVECAMPAIGN_VERSION}'.
	 * Here 1.x.x is the specific addon version, and
