Change dynCall to makeDynCall

The 
dynCall
function is deprecated. If you have any code that uses 
dynCall
, replace it with 
makeDynCall
. Make this change whether you have 
WebAssembly.Table
enabled or not.
For example, change:
dynCall('vii', callback, [1, 2])
to:
{{{ makeDynCall('vii', 'callback') }}}(1, 2)

Calling a function with no arguments

When migrating a 
dynCall
that has no arguments, you must add empty parentheses () after the 
makeDynCall
template to invoke the function.
For example, change:`
dynCall('v', callback, []);
to:
{{{ makeDynCall('v', 'callback') }}}()

Change Pointer_stringify() to UTF8ToString

The 
Pointer_stringify()
function is deprecated. If your code contains calls to 
Pointer_stringify()
, replace the calls with 
UTF8ToString()
.
For example, change:
var stringMessage = Pointer_stringify(message);
to:
var stringMessage = UTF8ToString(message);

Change unity.Instance to CreateUnityInstance

unity.Instance
is deprecated. If your code uses 
unity.Instance
, use 
CreateUnityInstance
instead.
For example, change:
var MyGameInstance = null;  script.onload = () => {    unity.Instance(canvas, config, (progress) => { /*...*/ }).then((unityInstance) => {
to:
var MyGameInstance = null;  script.onload = () => {    createUnityInstance(canvas, config, (progress) => { /*...*/ }).then((unityInstance) => {

Change gameInstance to unityInstance

The 
gameInstance
property is deprecated. If your code uses 
gameInstance
, use 
unityInstance
instead.
For example, change:
MyGameInstance = gameInstance;
to:
MyGameInstance = unityInstance;
