PHP 8.1 Deprecation: Clue\StreamFilter\CallbackFilter::onClose() should either be compatible with php_user_filter::onClose()

[rodrigoaguilera]

When I run this library with php 8.1.0 I get

Return type of Clue\StreamFilter\CallbackFilter::onClose() should either be compatible with php_user_filter::onClose(): void, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice 
in /vendor/clue/stream-filter/src/CallbackFilter.php:32

I think if compatibility with php 5 is still desirable the attribute annotation should be added.

@rodrigoaguilera Thanks for reporting, I've just filed #45 to address this for the upcoming release 👍

Hi @clue! When can we expect the release? Currently this is blocking for our project to move to PHP 8.1.

@pataar I'm sure you're going to like v1.6.0 has just been released! I hope this helps! If so, consider supporting this project, for example by becoming a sponsor ❤️
