This means that some apps written for an older SDK may no longer compile with the newer one. To help developers transition their code, these guides detail the specific changes they should look out for and highlighting the changes to APIs they may have previously been using. When breaking changes are made in the future, new guides will be added here to help developers make the required changes. ## Contents {% include guides/contents-group.md group=page.group_data %}
