• fixed: the _prepend.php file used by the demos would not locate the php autoloader when the library is installed as
  dependency

• fixed: setting a custom Parser or CharsetEncoder to the JsonRpc Value, Request, Response and Server classes does not
  reset anymore the same for the corresponding XmlRpc parent class, and vice-versa. This makes it possible to freely
  mix and match json-rpc and xml-rpc within the same php script.
  NB: this can have an impact in you access directly protected static members $parser and $charsetEncoder.

• improved: make it easy to allow CORS requests to the demo server on hosts other than the altervista one

• improved: moved the public demo server and debugger from altervista.org to tanoconsulting.com

• new: default the code to use json-rpc version 2.0 protocol, while allowing usage of json-rpc 1.0 too.

  The easiest way to switch everything to keep using version 1.0 is to add a call
  PhpJsonRpc::$defaultJsonrpcVersion = PhpJsonRpc::VERSION_1_0; at the beginning of your code

• new: added a Notification class, to be used for sending json-rpc notification calls

• breaking change: when creating a Request, passing in a NULL id will now automatically generate a unique id.
  To manually create notifications, use the new Notification class instead.
  Note that this change does not apply if using the legacy jsonrpcmsg class
  The "id" of both Request and Response objects has been made protected. To access it, use the id() method.

• breaking change: the Server will now respond to Notifications (request with no Id / null Id) with an HTTP 204
  response with no body

• breaking change: when sending a Notification call, Client::send() will now return true instead of a Response object,
  iff the server returns an empty http response body

• breaking change: when a Client sends invalid json, the returned response will sport a faultCode of 100+X, with X
  corresponding to the value returned by php function json_last_error, eg. 104 for no data, instead of previous 5

• breaking change: Parser::parseRequest() and Parser::parseResponse() always return an array, even on failure.
  Also, direct access to $parser->_xh is deprecated

• breaking change: classes Request and Response method and disallow access to the $id member. They gained an
  accessor method id() to retrieve the id

• breaking change: Serializer::serializeRequest() and Serializer::serializeResponse() have had the order of their
  arguments changed

• fixed: when receiving empty requests, the returned response's error code is now the same on php 5 as it is on
  later php versions

• fixed: PhpJsonRpc::setLogger() was not injecting the logger into the Serializer class

• fixed: removed warnings when running on php 8.5

• improved: it is now possible to set the Server option OPT_DEBUG_FORMAT to value 'extra_member', to have the debug
  info (emitted when the server debug level is > 2) serialized as an extra member in the response, rather than as
  a js comment, which requires a json5 parser or this library's client

• improved: the data returned by json-rpc method "interop.whichToolkit" now reports info about this package instead
  of info related to phpxmlrpc

• improved: added demos for client-side usage, as well as demos for symfony integration of both client and server

• improved: support for Value objects of type 'dateTime.iso8601' - even though datetimes are not part of JSON-RPC or JSON

• improved: more warnings are emitted in unexpected/unsupported scenarios (to the php error log by default)

• improved: added CI testing on php 8.4 and 8.5. Default the local testing container to using PHP 8.1 on Ubuntu Jammy

• bumped the minimum required version of phpxmlrpc/phpxmlrpc to 4.11.4

• other API changes:

  • classes Client, Request and Response gained methods getJsonRcVersion and setjsonRpcVersion
  • class Request has gained a 5th constructor argument: $jsonrpcVersion = null
  • class Request has gained a method: getParamName($i), useful for dealing with named-arguments requests.
    Also, its method addParam gained a 2nd argument: $name=null
  • class Request has gained a protected method: generateId()
  • visibility of Request::$content_type has been lowered from public to protected
  • class Response has gained a methods isFromServer and setIsFromServer($value)
  • method Server::execute() has gained a 5th param: $jsonrpcVersion = null
  • class Server now overrides more of the parent's methods
  • member client->$no_multicall defaults to null, as the support for multicall calls depends on the json-rpc version
    in use (version 2.0 does support it via "batch" calls)
  • member $parser->_xh has gained new elements
  • class Wrapper gained methods wrapJsonrpcServer and wrapJsonrpcMethod as aliases for existing methods, as well
    as members $prefix and $allowedResponseClass

• bumped the minimum required version of php to 5.4

• bumped the minimum required version of phpxmlrpc/phpxmlrpc to 4.10.1, fixing the Client->call method sometimes returning an xml-rpc response instead of a json-rpc one

• there is support for extra character sets than UTF-8/ISO-8859-1/ASCII when the php mbstring extension is installed, both as internal application charset and as received payload

• fixed: a "null" value was not considered a valid response

• fixed generation of comments server-side and parsing them client-side

• added method PhpJsonRpc::setLogger to allow overtaking the logger for all JsonRpc classes

• made all error messages go through the Logger facility instead of calling directly error_log

• made sure php warnings in method handlers do not disrupt the server even when it has debug level 0 and 1

• multiple fixes to accommodate changes in the phpxmlrpc to 4.10 API, including support for server-side per-method-handler parameter-types declarations and adding httpResponse data to parsed Responses

• fixed one warning with php 8.2 when running a Server

• fixed encoding of DateTime objects with php 5.4 in Encoder::encode

• prefer emitting "Content-type: application/json" to "Content-type: application/json; charset=UTF-8", as per the current RFCs

• fixes to demo files and benchmark.php

• run CI tests also on php 8.3

• BC notes: the Parser::parseRequest and Parser::parseResponse methods now accept (and are called with) a different set of arguments;
  they also return an array instead of true upon success

bumped the minimum required version of phpxmlrpc/phpxmlrpc to 4.9.2
