5. Register process has been removed.
6. Metrics stream process supports insert only mode, especially for traffic entities.
7. Metrics stream process supports no-downsampling mode for traffic entities and network alias.

* spring-cloud-gateway traceid does not transmit #3411
skywalking-version:6.5.0
spring-gateway-version:2.1.2
Error Description:
Customize the filter, traceid does not transmit.
"ServerWebExchangeDecorator" is a transport chain,His structure should be like this:
serverWebExchangeDecorator
-----(ServerWebExchangeDecorator)delegate
------(ServerWebExchangeDecorator)delegate
------.....
-----(DefaultServerWebExchange)delegate
In the current source code, there is no deep search, but only the next level. When there are multiple custom filters, you get an error.
Repair method:
Look for "delegate" of "ServerWebExchangeDecorator" recursively until "DefaultServerWebExchange"
