We have function to get changelog for a package when updating version. See code here.
However, the breaking changes do not contain the case that function parameter order change.
For example:
before:

func (client *AllPoliciesClient) NewListByServicePager(resourceGroupName string, serviceName string, options *AllPoliciesClientListByServiceOptions) *runtime.Pager[AllPoliciesClientListByServiceResponse]

after:

func (client *AllPoliciesClient) NewListByServicePager(serviceName string, resourceGroupName string, options *AllPoliciesClientListByServiceOptions) *runtime.Pager[AllPoliciesClientListByServiceResponse]

Two parameters serviceName and resourceGroupName have same type but different order. It should be a behavior breaking change.
We need to update the logic of finding function change here to support such cases.
E2E tests should be added here.
The detection logic should be reliable to prevent false positive. If there is only one param name change, it should not be detected. The parameters' name should keep same before after. Only the order changed.
