alasql: Promise not working in browser

The method .promise on the alasql object is not present when running in a browser.

Recreate: make a .html document with the following content:

<script src="http://cdn.jsdelivr.net/alasql/0.2/alasql.min.js"></script> 
<script>
    alasql.promise('SELECT 123 as abc ')
            .then(function(res){
                console.log('all OK');
            }).catch(function(err){
                console.log('not good');
            });
</script>

this gives an Uncaught TypeError: undefined is not a function on the line with alasql.promise('SELECT 123 as abc '). I have tried to include the promise polyfill from https://github.com/taylorhakes/promise-polyfill/blob/master/Promise.min.js but it did not solve the issue.

The same code gives an all OK in node:

alasql = require('alasql');
alasql.promise('SELECT 123 as abc ')
  .then(function(res){
  console.log('all OK');
}).catch(function(err){
  console.log('not good');
});
// all OK

I included the following fragment before the promise call and it worked. Thanks:

if(typeof Promise === ‘function’) { alasql.promise = function(sql, params) { return new Promise(function(resolve, reject){ alasql(sql, params, function(data,err) { if(err) { reject(err); } else { resolve(data); } }); }); }; }

Questions:

Why is the version number for alasql 3.0.2?
What value do you get from alasql.version?
Have you tried without including the promise.min.js part?
Can you create a minimum version of the code replicating the problem that you can share?
