Previously, `version: "3"` was equivalent to `version: "3.0"`, which caused confusion for many users, as they expected it to be "3.x". docker-compose and docker compose (v2) have adopted the compose-spec (https://compose-spec.io), which no longer has a version field in the compose file, and always picks the "latest" supported version. This changes how `docker stack` interprets "major" version numbers specified in compose-files: When only the major version ("3") is specified, it is now equivalent to "3.x" (latest supported v3 schema). Compose-files that specify both major and minor version (e.g. "3.0" or "3.1") continue to use the existing behavior; validation is down- graded to the specified version and will produce an error if options are used that are not supported in that schema version. This allows users to locally verify that a composse-file does not use options that are not supported in the intended deployment environment (for example if the deploy environment only supports older versions of the schema).
