Here are scheduled changes, deprecations, and retirements planned ahead for the Slack platform.
We tweet about most of these updates from @slackapi but we also offer this wonderfully antiquated RSS feed. Slack, the service and product, has its own changelog too.

- APIsBeginning June 10th, 2020, all newly created Slack apps will be unable to use the deprecated methods in
groups.*. Existing apps have until February 24th, 2021 to migrate to the Conversations API. Learn more.

replies array containing threaded message replies, we'll provide a lighter-weight list of
reply_users, plus a

replies array on
