What issue do you find in Pulsar docs?

If you check https://pulsar.apache.org/api/cpp/

There's no stable release after 2.5.0. All are snapshots and don't distinguish by patch versions.

What is your suggestion?

Figure out the reason, regenerate the content, and fix references to these pages.

I realized this issue as well. The release process doesn't include the release of C++ docs.

May I ask how we generate C++ API docs now? I don't find an entry talking about it...

@tisonkun https://github.com/apache/pulsar-client-cpp/pull/103 will fix the doxygen generation.
