Switching to Calendar Versioning: Does App Store Connect Support Underscores?

We plan to switch from Semantic Versioning (https://semver.org/) to Calendar Versioning (https://calver.org/).

Our intended format for CalVer is: YYYY.MM.DD_MICRO, such as 2025.1.5_3.

Question: Does App Store Connect allow underscores in version numbers?

The "Micro" component is included to handle cases where multiple releases occur on the same day.

Versioning on Apple platforms uses only numbers and periods. See the documentation for CFBundleVersion and also CFBundleShortVersionString for the exact requirements.
