Yesterday we released the first official release of the APaPi library for PHP – version 1.0. This release of the library implemented numerous bug fixes through the creation of unit test cases built on the PHPUnit framework. In addition to bug fixes this version of the library implements a strict mode that will throw exceptions if invalid requests are made, minimizing bad calls to the Amazon Product API.
