Hey @GrahamCampbell @Nyholm. Can we get these changes tagged? Thanks!

Waiting on a tag on the psr7 library, first. Still a PR over there that needs to be merged.

Which PR?

We will prepare a new minor release. I dont see anything blocking anymore

"just" need to write a change log. :P

@Nyholm can we merge the changes also in Guzzle 6.x?

src/Handler/MockHandler.php.

PHP Fatal error:  Uncaught Symfony\Component\ErrorHandler\Error\FatalError: Error: During inheritance of Countable: Uncaught Behat\Testwork\Call\Exception\CallErrorException: 8192: Return type of GuzzleHttp\Handler\MockHandler::count() should either be compatible with Countable::count(): int, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /app/vendor/guzzlehttp/guzzle/src/Handler/MockHandler.php line 173

We have our WMS still at Guzzle6 6.5.8
But we are almost ready to go to PHP8.1.

But upgrading to guzzle7 is not possilble at the moment, given we are waiting on several third party repos to implement 7 as well.
(like swagger-api/swagger-codegen#11123)

No. Guzzle 6 does not support PHP 8.1.
