 GitHub has a rich library of emojis, and these all work in additional approved words or denied words.  Some values GitHub will store in their text version - i.e. `:shipit:`. Other emojis, GitHub will store in their unicode emoji form, like ✅.
 For a seamless experience, it is recommended that you add the custom words to a GitHub comment, and then copy it back out of the comment into your actions configuration yaml.
 
+# v1.9.x → v1.10.0
+🚨 Update: Approval Issue Content Handling 🚨
+Starting from v1.10.0, the behaviour for issue contents has changed:
+- The issue-body and issue-body-file-path are now added as comments on the issue instead of being set as the issue’s main description/body.
+- The issue title is now exactly what is provided as input, instead of being appended to or wrapped in a predefined string.

 ## Org team approver
 
 If you want to have `approvers` set to an org team, then you need to take a different approach. The default [GitHub Actions automatic token](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token) does not have the necessary permissions to list out team members. If you would like to use this then you need to generate a token from a GitHub App with the correct set of permissions.
