Select2 will now automatically update the selection if there are options
added to or removed from the DOM within the `<select>` element. This is
supported in all browsers except for Internet Explorer 8. Internet
Explorer 8 does not support the DOM mutation events which were added in
Internet Explorer 9, and it does not support mutation observers which
are the recommended way of handling this in modern browsers.
DOM mutation events also trigger for the `<select>` itself when it is
pulled from the DOM, so we need to filter these out within the event
handler.
Despite supporting mutation observers, we cannot accurately detect if
the removed option was selected at one time or another, so we need to
always re-pull the selection when an element is deleted.

This builds upon https://github.com/select2/select2/pull/4249
Previously we hacked around the infinite loop between closeOnSelect and
selectOnClose by attempting to detect what event was being triggered
without knowing what event triggered it. Now we properly relay the
Select2 event and the jQuery event that triggered the select or unselect

This will include the event type in the _type property, so it can be
accessed within the event handlers if it's not normally passed in. This
should not conflict with any existing handlers, and this should not be
considered a public property on event arguments.
This adds basic support for focusing the Select2 element by triggering
the `focus` event on the underlying <select> element. This implicitly
adds support for <label> elements, which will trigger the `focus` event
on the `<select>` if it is clicked.
This also fixes the focus issue that previously existed if Select2 was
opened while in a <label>. The focus would be transferred to the search
dropdown, and then immediately pulled away to the <select> element. This
happened because the <label> element triggers the `focus` event when a
`click` event propagates its way up, and we do not stop the propagation
of the `click` event when it is triggered on the selection.

Previously the tokenizer only worked when creating multiple options
at once if all of the options existed. It always worked when creating
a single option, because all of the special cases were handled by the
tagging module. When working with multiple options, the tagging
module does not kick in until after the query has been run, which
is when the tokenizer does its magic.
This fixes the issue by automatically creating the option tags that
the tagging module would normally create. It only does this if the
options do not already exist, so we don't need to worry about the
tokenizer creating duplicates of existing options.

The error handler should not be raised if a request is aborted while
another one is sent out. This attempts to detect those cases by
handling the case where the error was raised and the request has a
status code of 0, which should either mean we're in offline mode or
the request was aborted.

Previously the `dropdownAutoWidth` option didn't work because the
dropdown was being absolutely positioned, so setting the width to
`auto` didn't actually have an effect. This cannot be solved by
just setting the width on the container, because that is also
absolutely positioned.

This fixes an issue that has existed since Select2 4.0.1 where the
arguments passed into each `<select>` were mutated. This no longer
mutates the arguments for each element, and instead only drops the
first argument once.

This fixes an edge case that occurred pretty much whenever anyone would
use array data with existing selections along with a placeholder. This
caused the existing selections to be discarded, because the `selected`
property was not being transferred over to the new option. This was
based the new data was being preferred over the data that could be
inferred from the option, and the new data typically did not include the
selected state. As a result, the option was assumed to not be selected.
This was not cause by existing tests because all of the existing tests
only covered cases where the selected option was the first option, and
that was not affected by this bug.
This call to `$.fn.position` was causing an error in IE 8 because the
`offsetParent` was null on the container for some reason. It's not
needed, so this line of code has been removed.
This should fix the test failures in IE 8.
There was a commit that landed in 4.0.1 that fixed positioning for
non-static elements, which are commonly used for the custom
`dropdownParent` option, but broke positioning for statically positioned
elements, commonly used in almost every other case. That commit was
c9216b4b96
This fixes the positioning issues caused by that commit by properly
calculating the offsets for statically positioned parents. Statically
positioned parents are unique, because the offset for the dropdown must
be calculated based on the closest element that is non-statically
positioned. Otherwise, the offset for any statically positioned parent
other than the body will be considerably higher than it should be,
resulting in the dropdown being offset by a large amount.
The offset parent for the body element is the html element, which is why
this works for both the body element and any custom parents for the
dropdown. This would not be needed if the parent wasn't customizable (as
seen in Select2 3.x) because you will never need to offset the body
element if it is statically positioned, because the html element almost
never has an offset.
This also fixes JSHint issues within the tests added in the last commit.

This fixes an infinite loop that used to be caused when both
`closeOnSelect` and `selectOnClose` used to be combined, because they
both were listening to events triggered by the other one. The problem
was that `selectOnClose` was triggering `select` events for data objects
which had already been selected. This problem was solved by checking if
the data object was already selected before trying to select it again.

In
f1e86470ca
we tried to fix the issue where multiple instances created in a single
call would share the same options, and this worked for the most common
cases. Unfortunately it did not work for the case where data attributes
were also used with an options object, and as a result data attributes
would be copied to all instances. Data attributes are supposed to be
specific to a single instance.
This was fixed by moving the `true` for the deep copy to the start of
the `$.extend` call, as this is where jQuery looks for the deep copy
flag.

This fixes a previous bug with the backspace handler on the multiple
select search box where unselecting a choice through the keyboard would
not properly size the search box. As a result, most of the text would be
cut off and it was very clear that there was an issue.
In addition, a blank space was automatically being added to the end of
the search query. This blank space would not be removed at all, so the
user had to manually remove it.
Additionally, a query would be triggered for the last used search term
instead of the new search term that would be loaded in. This caused
incorrect results to be displayed most of the time.
All of these issues have been fixed by triggering a new search query
after an option has been removed through the keyboard. This will resize
the search box automatically, which fixes the main issue, and it will
trigger a search with the correct query.

This fixes an issue when any of Select2's special options are called on
multiple elements, it would only affect the first option in the group.
This was because Select2 was only applying any changes to the first
element in the group (as chosen by jQuery) instead of applying changes
on each and every element within the list.
This has the new side effect of special options like `select2('data')`
returning the results for the last element in the list instead of the
first element. Because the previous functionality was considered
unspecified behaviour, this is not being treated as a breaking change.

This will now pass all of the AJAX parameters into the AJAX request as
query string parameters, so now the page number (and other variables)
will be set automatically. This can still be overridden in `ajax.data`
to pass anything else, but this should make it easier for the most
common case.

This fixes an issue where the old `option` and `load-more` classes were
not switched over to the newer BEM style of class names. Unfortunately
this is a breaking change, but this is also a bug given that it doesn't
follow the proper prefixing and is likely to conflict with larger
applications.

Previously `this` would point to the AjaxAdapter that was being used to
process the AJAX, or sometimes the JS object holding the AJAX options,
instead of the jQuery element that Select2 was attached to. This fixes
the issue so `this` will consistently point to the jQuery element, just
like in past versions of Select2.

About `errorLoading`:
Before the correction, the translation was: "התוצאות לא נטענו בהלכה".
The word "בהלכה" is wrong and should be spelled "כהלכה", but besides that, this translations means "The results were loaded improperly", while my corrected translation means "Error while loading results", which is what needed.
About `inputTooLong`, `inputTooShort`, `maximumSelected`:
In Hebrew, it's not acceptable to have the digit 1 for representing a single object. You should use the actual word "one", which is "אחד" in Hebrew together with the singular noun (e.g. "one item" / "one character", instead of "1 item" / "1 character").
**These 3 parts needed a critical fix anyway**, because they were addind the English letter 's' to the end of the Hebrew string.
About `loadingMore`:
The translation was "טען תוצאות נוספות" which means "Load more results", as an instruction, probably a typo.
I changed "טען" to "טוען" so now it means "loading more results", which is the correct form.

Previously we were only disabling the `input` handler when it was
triggered, which caused a race condition within the `keyup` handlers
which also was triggered by the `input` event. This fixes the issue by
also unbinding the `input` handlers within the `keyup` handler, to avoid
running into the race condition.
Thanks to @Eckankar for pointing out the race condition that still
existed in

The `createTag` option does allow for `null` to be returned if a
tag should not be created. The tokenizer previously didn't support
this, so the tokenizer should be able to handle this case. Previously
it would trigger an exception, because the tokenizer would pass back
a null value to the select function.
This also fixes what would have been a potential bug where even if a
tag was not created, the term would still have been sliced at the
location of the token. This allows for tokenizers to have special
cases when tokenizing the term, such as not splittting a token
if it is in the middle of a quoted string.

This fixes an issue where preventing the default behaviour on some
events would trigger an exception. This was bacause the event relay

and this wasn't always the case.

This prevents selections from being removed when the container is
disabled. This stops any click events that are triggered on the
remove button, so the remove handler won't be triggered at all.
This closes https://github.com/select2/select2/pull/3636.
In the previous commit (02cca7b) support was added for multiple
selects to automatically focus when they were tabbed into. While
this did actually work, it caused a few bugs with the focus that
prevented users from tabbing out of the container, effectively
trapping keyboard users in Select2.
This makes a few major changes to how things work in Select2, but
should not break any backwards compatibility.
- The internal `focus` event is now proxied through a `focus`
method on the core object. This allows for two important things
1. The `focus` event will only be triggered if Select2 was in an
unfocused state.
2. Select2 now (unofficially) supports the `select2('focus')`
method again.
But that does mean that it is possible to trigger the `focus`
event now and not have it propagate throughout the widget. As
it would previously trigger multiple times, even when Select2
had not actually lost focus, this is considered a fix to a bug
instead of a breaking change.
- The internal `blur` event in selections is only triggered when
the focus is moved off of all elements within the selection. This
allows for better tracking of where the focus is within Select2,
but as a result of the asynchronous approach it does mean that the
`blur` event is not necessarily synchronous and may be more
difficult to trace.
- On multiple selects, the standard selection container is never
visually focused. Instead, the focus is always shifted over to
the search box when it is requested. The tab index of the selection
container is also always copied to the search box, so the search
will always be in the tab order instead of the selection container.
It's important to note that these changes to the tab order and how
the focus is shifted do not apply to multiple selects that do not
have a search box. Those changes also do not apply to single select
boxes, which will still have the same focus and tabbing behaviours
as they previously did.
