when spring boot integrates with zipkin, the dependent versions of many online tutorials are as follows:

<artifactId>brave-core</artifactId>
<artifactId>brave-spancollector-http</artifactId>
<artifactId>brave-web-servlet-filter</artifactId>
<artifactId>brave-apache-http-interceptors</artifactId>
<version>3.9.0</version>

then set up a configuration bean to inject Bean such as SpanCollector, Brave, BraveServletFilter, CloseableHttpClient, etc., but when I changed the dependency version to the latest 4.16.3, these classes were marked as obsolete, but there was no detailed documentation on github. The specific questions are as follows:
1. Where can I see the relevant official documents? It"s brave, not zipkin.
2. How to choose the version when using it? (boot integration only, non-cloud integration)
