草稿箱升级问题

您好作者大人，我看到 区别于 jianyingdraft,
draft_content_template.json里面的软件版本是6.70版本，是最高可以支持到这个版本吗。 我在5.7版本中生成草稿箱，会提示让升级才能打开，请问这种情况是要改一下这个版本号吗
"last_modified_platform": {
"app_id": 359289,
"app_source": "cc",
"app_version": "6.7.0",
"os": "windows"

Start by inspecting draft_content_template.json and the code that generates the draft metadata, then reproduce opening a generated draft in CapCut 5.7. Compare the declared app_version with the version expectations described in the issue and any related jianyingdraft behavior. Done means the supported-version behavior is established and the required compatibility change or documentation is clearly identified.
