WordPress 4.6 Beta 2 发布了，主要更新如下： Meta: The fallback authentication for the previous registration method has been restored. Also, retrieving registered metadata now works and non-core object types are no longer forcibly blocked. See #35658. REST API: The order of setting sanitization and validation has been reversed; validation now occurs prior to sanitization. Previously, the sanitization callback ran before the validation callback. See #37192. Customize: The order of setting sanitization and validation has been reversed; validation now occurs prior to sanitization. See #37247. HTTP API: WP_Http::request() returns an array again. See #37097. Various bug fixes.
