prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Release 'api_core-1.6.0a2'? or 'api_core-1.5.1'?
  I'd like to use the changes from https://github.com/googleapis/google-cloud-python/pull/6310 in the library I'm working on.
  
  Not sure about the version number for that one, since:
  
  - I don't know what else has been released since 1.6.0a1
  - I don't know what is intended by 1.6.0a1 in https://github.com/googleapis/google-cloud-python/pull/6267 (is it a pre-release?)
