Fatal caused by upgrade to 4.7.0

Second that.
Anything that uses GuzzleHttp is now crashing (for example intercom-php).

Please fix this

Any update this issue?

I found this error and make the conflict with WooCommerce Xero Integration plugin. Please help to investigate.

Same here. I use GuzzleHttp for customization in my theme. I noticed other plugins use something like https://github.com/humbug/php-scoper when using 3rd party dependencies. For example: https://github.com/deliciousbrains/wp-offload-ses-lite/blob/master/vendor/Aws3/GuzzleHttp/Utils.php#L3-L7

Thank you!

We are having the same issue with 4.7.0 – reverting to 4.6.0 resolve the issue

Issue persists
