SPI	Marker for extension interface Changes on extension configuration file Use Protocol as an example, its configuration file 'META-INF/dubbo/com.xxx.Protocol' is changed from: com.foo.XxxProtocol com.foo.YyyProtocol to key-value pair xxx=com.foo.XxxProtocol yyy=com.foo.YyyProtocol The reason for this change is: If there's third party library referenced by static field or by method in extension implementation, its class will fail to initialize if the third party library doesn't exist.
Wrapper	The annotated class will only work as a wrapper when the condition matches.
