You can now add free text to a check-in question, meaning that your manager and future you can know why you picked the answer you did.
Also from now, your manager's manager (and their manager and their manager's manager) will be able to see your check-in results, so those planning the team can know what everyone's strengths are. Hooray!
Finally, you can now have control over whether your team uses check-ins by switching 'edge features' on and off. You can do that from your edit team page at any time.
