# ChangeLog v4 ## 4.0.0, 2021-01-13 Changes from beta1: * Fixed configure on systems which do not provide icu-config * Fixed gh-issue #89: Cookie handling cannot be disabled since v3.2.1 ## 4.0.0beta1, 2020-09-23 * PHP 8 compatibility - Drop ext-propro support: PHP 8 removes the object get/set API from the ZendEngine, which renders that extension dysfunctional. As a consequence, the header property of http\Message and derived classes cannot be modified in place, and thus by reference.
