+As of Spring Cloud 2021.0.8, Spring Cloud will now call `PropertySourceLocators` twice.  The first fetch
+will retrieve any property sources without any profiles.  These property sources will have the opportunity to
+activate profiles using `spring.profiles.active`.  After the main application context starts `PropertySourceLocators`
+will be called a second time, this time with any active profiles allowing `PropertySourceLocators` to locate
+any additional `PropertySources` with profiles.

 === Logging Configuration
 
 If you use Spring Boot to configure log settings, you should place this configuration in `bootstrap.[yml | properties]` if you would like it to apply to all events.
