What's New

• Add IsEmailConfirmed to User by @​nlopes in https://github.com/slack-go/slack/pull/1458

Fixes

• Parse simple string based errors as part of the response by @​nlopes in https://github.com/slack-go/slack/pull/1452
  In the previous version we introduced the ability to parse specific errors (more complex ones) but Slack can still send us a string. string is now the fallback type.

Other

• Examples are now using environment variables and command line arguments consistently by @​nlopes in https://github.com/slack-go/slack/pull/1456
  Also added a ./examples/README.md explaining the patterns that should be used.
