+
+XML-RPC for PHP version 4.1.1 - 2016/10/1
+
+* fixed: error in server class: undefined function php_xmlrpc_encode (only triggered when not using the compatibility
+ shim with old versions)
+
+
+XML-RPC for PHP version 4.1.0 - 2016/6/26
+
+* improved: Added support for receiving <I8> and <EX:I8> integers, sending <I8>
+
+ If php is compiled in 32 bit mode, and an i8 int is received from a 3rd party, and error will be emitted.
+ Integers sent from the library to 3rd parties can be encoded using the i8 tag, but default to using 'int' by default;
+ the developer will have to create values as i8 explicitly if needed.
+ The library does *not* check if an outgoing integer is too big to fit in 4 bytes and convert it to an i8 automatically.
