Current version of `php-src@master` fails when running `phpsdk_deps -u` with the following: ``` Fatal error: Uncaught SDK\Exception: Unsupported branch '8.4' in D:\php-sdk\lib\php\libsdk\SDK\Config.php:183 Stack trace: #0 D:\php-sdk\bin\phpsdk_deps.php(105): SDK\Config::setCurrentBranchName('8.4') #1 {main} thrown in D:\php-sdk\lib\php\libsdk\SDK\Config.php on line 183 ``` It appears to be because the definition for 8.4 is absent from http://downloads.php.net/~windows/php-sdk/deps/series/.
