Additional context

Any additional information relevant to the issue, for example PHP/environment config settings if the issue is related to memory or performance.
Using zendframework/zend-servicemanager 2.7.11, which is supposed to be supported from reading the composer.json file

[devkokov]

I realise now this is explained in the README, but maybe composer.json needs changing to reflect this i.e.
from
"zendframework/zend-servicemanager": "^2.7.0 || ^3.0",
to
"zendframework/zend-servicemanager": "^3.0",

@devkokov I think that is expected behavior, and changing it might be a breaking change for some people. What do you think?

[devkokov]

It would be a breaking change for anyone using v2.7 of zendframework/zend-servicemanager, however in my experience this version of the service manager doesn't work with v4 of aws-sdk-php-zf2 anyway. (hence raising this issue)
Unless I'm missing something
