Apple is updating Gatekeeper in macOS 13 Ventura to ensure that apps are not changed since notarization. macOS 13 Ventura will also prevent apps to update apps not coming from the same vendor. This might affect third-party app distribution services and will require all apps to be signed by same vendor.
Reference: Gatekeeper Changes in macOS Ventura
Developer:Beware of changes, avoid practices that could trigger Gatekeeper warnings.
QA engineer:Test all app scenarios that could affect apps signature.
PM/DM:Update backlog to include app updates, if necessary.
