Two comments:

1. please signoff the commit using command git rebase HEAD~1 --signoff;
2. Please consider to add a couple of unit tests to verify the changes.

I have modified and added unit tests.

@happlins you need to combine four commits into one

sorry,I have revised it.

The minimum version supported should be 3.4, so probably we should update min at client.go#L510.

Please also consider to enhance the unit test to cover more scenarios,such as,

1. All endpoint versions are up to date;
2. All endpoint versions are out of date;
3. Partially endpoint versions are out of date;

any update on this?

I'm sorry. I've been too busy recently. I've modified the minimum version and added unit test

Since there is no response from other maintainers and it's a safe change to me, so let me merge this PR.
