Now we do not have separate AMD builds, instead we use a UMD wrapper
to support both AMD and CommonJS environments along with the browser.
This has been tested with RequireJS and it correctly imports Select2
and hooks into jQuery.
This means that all builds will include the Almond AMD loader, but
this isn't that much of an issue when you consider the file sizes.
The loader is namespaced so RequireJS and other AMD builders don't
complain about `require` and `define` existing. This is also done
so AMD loaders don't conflict, as Select2's AMD loader should
operate independently of others.
There are now two layers of wrappers that are applied to files,
only one of which is used for the translation files. This allows
us to only load in the internal Select2 modules once, and in
general makes most things cleaner. These have also been pulled out
into individual JS files instead of being stored in JSON files,
allowing us to add comments and make things look readable.
Because we use a few hacks, these files are heavily commented as well.

We don't need to update the dates on these every time that grunt
is called. This gives it a much more basic banner that is similar
to the minified version.
As we have established already, jQuery 1.x does not correctly handle
`data-*` attributes where there are multiple dashes. This makes it
so we can still handle nested options when working with jQuery 1.x
by using the `.dataset` option that is supported by all major
browsers as well as IE 11+.
Browser support tables for the `.dataset` attributes can be found at
http://caniuse.com/dataset
A notice was already added to the documentation about this in
caeb0ec9b7.
The related ticket in the jQuery repository about this issue is

This closes https://github.com/select2/select2/issues/2969.
There were a few undefined variables being referenced within the
Select2 code. The JSHint configuration has been modified to fail
if there are undefined variables being referenced, including any
global variables.
There is an exception that is being made for the jQuery shim, as it
must try to find the global jQuery references.
An exception is made for the test helpers, as the SauceLabs reporting
variables are not camelCase, and would normally trigger warnings.
This closes https://github.com/select2/select2/pull/3028.
This adds a check that triggers an error if Select2 was not able
to detect a copy of jQuery on the page. This should help users when
they are setting up Select2.
**Breaking change:** The full build no longer includes jQuery.
Previously, the full build included all requirements for Select2,
including jQuery, which meant that anyone looking for the optional
requirements had to possibly include multiple versions of jQuery
on their page. This means that anyone requiring Select2 to also
bundle jQuery will now need to include jQuery on their pages
alongside Select2. A copy of jQuery is included in the repository.
**Breaking change:** The AMD build of Select2 will now correctly
wrap the code in a `define` block. It will still create the named
blocks inside of the code, which should be valid in most AMD build
systems, so now Select2 is compatible with cases where the file
does not have the same name as the Select2 module name.
**Breaking change:** Select2 will re-use the AMD methods if they
are available on the page, but it will not longer leak the included
AMD loader to the global scope. The AMD methods will still be
available on the `jQuery.fn.select2.amd` namespace.
The `mock.js` test file has been renamed to `helpers.js` and will
handle the escalation of the `require` and `define` variables to
the global scope. It should be included in all test files, or the
tests will fail.
This closes https://github.com/select2/select2/issues/2946.
When `jQuery.noConflict` is called, the global `$` variable is not
defined. We cannot assume in the code that the variable is defined,
and instead should always make sure to import the `jquery` module
when we need jQuery.
This fixes all of the issues where we are assuming that `$` is
defined globally when we are not importing the module. This also
fixes the issues when defining the `jQuery.fn.select2.amd` modules
where we were always attaching to the `$` object instead of the
`jQuery` object.
This closes https://github.com/select2/select2/issues/2947.
This exposes the default options for Select2 as
`$.fn.select2.defaults`. A default option can be set using the
`set(key, val)` option which is available. The key should use the
same formatting as the HTML data attributes.
This also adds some documentation about it.
This adds basic tests to ensure that the selection is accessible by
all users. This checks for common attributes, ensuring that the
container is always keyboard accessible and follows ARIA guidelines.
This also changes the base selection to create a common element so
we don't need to repeat attributes and such across multiple selection
containers.
This adds the `select` and `unselect` events so users can still
hook into them from their jQuery plugins.
This also modifies the core `trigger` to fire pre-events that can
be canceled for the `open`, `close`, `select`, and `unselect`
events. Users implementing these events who need to handle cases
where the event has been prevented should check `args.prevented`,
where `args` is the object that was included for arguments when
triggering the internal event.
There was a plan to universally use an array as the return from
query methods, but now that we've realized pagination and extra
things are impossible without it, we're going back to the return
object. Anyone looking to migrate their data should be returning
an object with the key `results` containing what they previously
returned.
This should fix https://github.com/select2/select2/issues/2898
This migrates over the required English translations under their
new names.
The "Searching" message has also been adjusted to use "Searching..."
instead of "Loading more results...", which is what it used to
say sometimes.
This also changes the AJAX handler to call `abort` when needed.
This adds a custom r.js build for i18n, which processes each JS
file in the `select2/i18n` directory and builds it.
So far only the "No results found" translation has been added.
