datetime format bug for jquery.inputmask 3.3.4?

Question

when I upgrade my jquery.inputmask plugin from 3.3.1 to 3.3.4, I noticed that datetime format for mask is changed.

// in version 3.3.1
$("#textbox").inputmask("y-m-d");
$("#textbox").inputmask("h:s");

// in version 3.3.4
$("#textbox").inputmask("yyyy-mm-dd");
$("#textbox").inputmask("hh:mm");

In v3.3.4, letter "m" is used for both "month" and "minute", some mask definitions are likely to cause conficts, for example

$("#textbox").inputmask("yyyy-mm-dd hh:mm"); // ERROR! can't input anything into textbox 
$("#textbox").inputmask("mm/dd/yyyy hh:mm xm"); // but this works fine

This problem only happens in jquery.inputmask 3.3.4

Is it a bug? How can I make the mask "year-month-day hour:minute" work in my page ?

After a bit of digging into the source code, it looks like you can use Inputmask.extendAliases to correct the bug by adding a custom alias for your specific use case:

Inputmask.extendAliases({
  "yyyy-mm-dd hh:mm": {
    mask: "y-1-2 h:s",
    placeholder: "yyyy-mm-dd hh:mm",
    alias: "datetime",
    separator: "-"
  }
})

$("#textbox").inputmask("yyyy-mm-dd hh:mm")
