Hi All, Following is a draft email for the announcement, how do you think?
=== The Apache Dubbo(incubating) team announces that support for Apache Dubbo 2.5.x will end on 2019-6-15. If you are still using 2.5.x, it is highly recommended to upgrade to 2.6.x. This means that after 2019-6-15: * releases from the 2.5.x branch are highly unlikely * bugs affecting only the 2.5.x branch will not be addressed * security vulnerability reports will not be checked against the 2.5.x branch -- Best Regards！ Huxing
