I was checking Connect to Forge migration documentation: https://developer.atlassian.com/platform/forge/build-a-connect-on-forge-app/ and there is option to rewrite the app from scratch in Forge: Option A: Re-writing with Forge modules
Looks like you can do a complete rewrite in Forge and reference the Connect app key in manifest file.
app: id: <the-unique-id-of-your-app> connect: key: <your-connect-key>
That is very nice. My question is what happens when you release the new version in the Marketplace?
Will the new version be released as a new version of the same app, or do I need to create a completely new listing?
