 - Add `before_send_check_in` for applying to `CheckInEvent` ([#2703](https://github.com/getsentry/sentry-ruby/pull/2703))
 - Returning a hash from `before_send` and `before_send_transaction` is no longer supported and will drop the event.
 - Remove stacktrace trimming ([#2714](https://github.com/getsentry/sentry-ruby/pull/2714))
+- `config.enabled_environments` now defaults to `nil` instead of `[]` for sending to all environments ([#2716](https://github.com/getsentry/sentry-ruby/pull/2716))
