There are several bug fixes already merged in master https://github.com/apache/pulsar-client-go/pulls?q=is%3Apr+milestone%3A0.5.0+is%3Aclosed
In particular the Zstd repository name change (fixed in https://github.com/apache/pulsar-client-go/pull/465 ) is preventing to compile the current 0.4.0 tag. For that reason, I think we should be releasing a 0.5.0 version with what we have today. Thanks, Matteo -- Matteo Merli <mme...@apache.org>
