Hi all, There is a regression related to OAuth2 authentication for C++ Client 3.4.0 and 3.4.1: https://github.com/apache/pulsar-client-cpp/issues/363
Generally, for C++ client users, you won't be affected if you - don't use OAuth2 authentication - or build the library from source in your platform - or use the RPM/DEB/APK pre-built libraries If you're using pre-built libraries for macOS or you built the Linux libraries in a specific platform (e.g. RedHat) but provided the libraries in various Linux platforms (e.g. Ubuntu), there would be no way to use OAuth2 authentication. Python and Node.js clients would also be affected because they rely on the customized `tlsTrustCertsFilePath` config that specifies the CA cert path for OAuth2 authentication. Therefore, I pushed a fix (https://github.com/apache/pulsar-client-cpp/pull/364) and will start the 3.4.2 release. Thanks, Yunze
