the next release will be beta.2
- release-it added the `preReleaseBase` option and we
now always set it to `1` in the npm script. This is
a noop for stable releases.

We cannot pass a single file via the `module` condition as then
`require( "jquery" )` will not return jQuery but instead the module object
with `default`, `$` & `jQuery` as keys. Instead:
1. For Node.js, detected via the `node` condition:
1. Expose a regular CommonJS version to `require`
2. Expose a tiny wrapper over CommonJS to `import`
2. For bundlers, detected via the `module` condition:
1. Expose a regular ESM version to `import`
2. Expose a tiny wrapper over ESM to `require`
3. If neither Node.js nor bundlers are detected (no `node` or `module`
conditions`):
1. Expose a regular CommonJS version to `require`
2. Expose a regular ESM version to `import`
The reasons for such definitions are as follows:
1. In Node.js, one can synchronously import from a CommonJS file inside of
an ESM one but not vice-versa. To use an ESM file in a CommonJS one,
a dynamic import is required and that forces asynchronicity.
2. In some bundlers CommonJS is not necessarily enabled - e.g. in Rollup without
the CommonJS plugin. Therefore, the ESM version needs to be pure ESM.
However, bundlers allow synchronously calling `require` on an ESM file. This
is possible since bundlers merge the files before they are passed to
the browser to execute and the final bundles no longer contain async import
code.
3. Bare ESM & CommonJS versions are provided to non-Node non-bundler
environments where we cannot assume interoperability between ESM & CommonJS
is supported.
4. Bare versions cannot be supplied to Node or bundlers as projects using both
ESM & CommonJS to fetch jQuery would result in duplicate jQuery instances,
leading to increased JS size and disjoint data storage.
In addition to the above changes, the `script` condition has been dropped. Only
Webpack documents this condition and it's not clear when exactly it's triggered.
Adding support for a new condition can be added later without a breaking change;
removing is not so easy.
The `production` & `development` conditions have been removed as well. They were
not really applied correctly; we'd need to provide both of them to each current
leaf which would double the size of the definition for the `.` & `./slim` entry
points. In jQuery, the only difference between development & production builds
is minification; there are no logic changes so we can pass unminified versions
to all the tooling, expecting minification down the line.
As for the factory entry points:
1. Node.js always gets the CommonJS version
2. Bundlers always get the ESM version
3. Other tools take the ESM version when using `import` and the CommonJS when
using `require`.
The complexity is lower than for the `.` & `./slim` entry points because there's
no default export to handle so Node/bundler wrapper files are not necessary.
Other changes:
* Tests: Change "node:assert" to "node:assert/strict"; the former is deprecated
* Docs: Mention that the CommonJS module doesn't expose named exports
* Tests: Run Node & bundler tests for all the above cases

This is a complete rework of our testing infrastructure. The main goal is to modernize and drop deprecated or undermaintained dependencies (specifically, grunt, karma, and testswarm). We've achieved that by limiting our dependency list to ones that are unlikely to drop support any time soon. The new dependency list includes:
- `qunit` (our trusty unit testing library)
- `selenium-webdriver` (for spinning up local browsers)
- `express` (for starting a test server and adding middleware)
- express middleware includes uses of `body-parser` and `raw-body`
- `yargs` (for constructing a CLI with pretty help text)
- BrowserStack (for running each of our QUnit modules separately in all of our supported browsers)
- `browserstack-local` (for opening a local tunnel. This is the same package still currently used in the new Browserstack SDK)
- We are not using any other BrowserStack library. The newest BrowserStack SDK does not fit our needs (and isn't open source). Existing libraries, such as `node-browserstack` or `browserstack-runner`, either do not quite fit our needs, are under-maintained and out-of-date, or are not robust enough to meet all of our requirements. We instead call the [BrowserStack REST API](https://github.com/browserstack/api) directly.
## BrowserStack Runner
- automatically retries individual modules in case of test failure(s)
- automatically attempts to re-establish broken tunnels
- automatically refreshes the page in case a test run has stalled
- runs all browsers concurrently and uses as many sessions as are available under the BrowserStack plan. It will wait for available sessions if there are none.
- supports filtering the available list of browsers by browser name, browser version, device, OS, and OS version (see `npm run test:unit -- --list-browsers` for more info). It will retrieve the latest matching browser available if any of those parameters are not specified.
- cleans up after itself (closes the local tunnel, stops the test server, etc.)
- Requires `BROWSERSTACK_USERNAME` and `BROWSERSTACK_ACCESS_KEY` environment variables.
## Selenium Runner
- supports running any local browser as long as the driver is installed, including support for headless mode in Chrome, FF, and Edge
- supports running `basic` tests on the latest [jsdom](https://github.com/jsdom/jsdom#readme), which can be seen in action in this PR (see `test:browserless`)
- Node tests will run as before in PRs and all non-dependabot branches, but now includes tests on real Safari in a GH actions macos image instead of playwright-webkit.
- can run multiple browsers and multiple modules concurrently
Other notes:
- Stale dependencies have been removed and all remaining dependencies have been upgraded with a few exceptions:
- `sinon`: stopped supporting IE in version 10. But, `sinon` has been updated to 9.x.
- `husky`: latest does not support Node 10 and runs on `npm install`. Needed for now until git builds are migrated to GitHub Actions.
- `rollup`: latest does not support Node 10. Needed for now until git builds are migrated to GitHub Actions.
- BrowserStack tests are set to run on each `main` branch commit
- `debug` mode leaves Selenium browsers open whether they pass or fail and leaves browsers with test failures open on BrowserStack. The latter is to avoid leaving open too many sessions.
- This PR includes a workflow to dispatch BrowserStack runs on-demand
- The Node version used for most workflow tests has been upgraded to 20.x
- updated supportjQuery to 3.7.1

Since versions 1.11.0/2.1.0, jQuery has used a module wrapper with one strange
addition - in CommonJS environments, if a global `window` with a `document` was
not present, jQuery exported a factory accepting a `window` implementation and
returning jQuery.
This approach created a number of problems:
1. Properly typing jQuery would be a nightmare as the exported value depends on
the environment. In practice, typing definitions ignored the factory case.
2. Since we now use named exports for the jQuery module version, it felt weird
to have `jQuery` and `$` pointing to the factory instead of real jQuery.
Instead, for jQuery 4.0 we leverage the just added `exports` field in
`package.json` to expose completely separate factory entry points: one for the
full build, one for the slim one.
Exports definitions for `./factory` & `./factory-slim` are simpler than for `.`
and `./slim` - this is because it's a new entry point, we only expose a named
export and so there's no issue with just pointing Node.js to the CommonJS
version (we cannot use the module version for `import` from Node.js to avoid
double package hazard). The factory entry points are also not meant for the Web
browser which always has a proper `window` - and they'd be unfit for an
inclusion in a regular script tag anyway. Because of that, we also don't
generate minified versions of these entry points.
The factory files are not pushed to the CDN since they are mostly aimed
at Node.js.

The `default` export is treated differently across tooling when transpiled
to CommonJS - tools differ on whether `module.exports` represents the full
module object or just its default export. Switch `src/` modules to named
exports for tooling consistency.
Fixes gh-5262
Closes gh-5292
Summary of the changes:
* define the `exports` field in `package.json`; `jQuery` & `$` are also
exported as named exports in ESM builds now
* declare `"type": "module"` globally except for the `build` folder
* add the `--esm` option to `grunt custom`, generating jQuery as an ECMAScript
module into the `dist-module` folder
* expand `node_smoke_tests` to test the slim & ESM builds and their various
combinations; also, test both jQuery loaded via a path to the file as well
as from module specifiers that should be parsed via the `exports` feature
* add details about ESM usage to the release package README
* run `compare_size` on all built minified files; don't run it anymore on
unminified files where they don't provide lots of value
* remove the remove_map_comment task; SWC doesn't insert the
`//# sourceMappingURL=` pragma by default so there's nothing to strip

With this change, jQuery build no longer generates the `amd` directory with
AMD modules transpiled from source `src` ECMAScript Modules. To use individual
jQuery modules from source, ESM is now required.
Note that this DOES NOT affect the main `"jquery"` AMD module defined by built
jQuery files; those remain supported.
Closes gh-5276
UglifyJS is ES5-only, while Terser supports newer ECMAScript versions. jQuery
is authored in ES5 but jQuery 4.x will also have an ESM build that cannot be
minified using UglifyJS directly.
We could strip the `export` statement, minify via UglifyJS and re-add one but
that increases complexity & may not fully play nice with source maps.
On the other hand, switching to Terser increases the minfied size by just 324
bytes and the minified gzipped one by just 70 bytes. Such differences largely
disappear among bigger size gains from the `3.x-stable` line - around 2.7 KB
minified gzipped as of now.
Closes gh-5258
Re-introduce the `selector-native` similar to the one on the `3.x-stable`
branch. One difference is since the `main` branch inlined Sizzle, some
selector utils can be shared between the main `selector` module and
`selector-native`.
The main `selector` module can be disabled in favor of `selector-native`
via:
grunt custom:-selector
Other changes:
* Tests: Fix Safari detection - Chrome Headless has a different user
agent than Safari and a browser check in selector tests didn't take
that into account.
* Tests: Run selector-native tests in `npm test`
* Selector: Fix querying on document fragments

Introduces a new test API, `includesModule`. The method returns whether
a particular module like "ajax" or "deprecated" is included in the current
jQuery build; it handles the slim build as well. The util was created so that
we don't treat presence of particular APIs to decide whether to run a test as
then if we accidentally remove an API, the tests would still not fail.
Fixes gh-5069
Closes gh-5046
The queue module is not present in the slim build as it depends on deferred
and our Gruntfile specifies excluding deferred should also exclude queue:
https://github.com/jquery/jquery/blob/3.5.1/Gruntfile.js#L66
This commit makes this exclusion explicit so that the queue module never
accidentally gets re-included in the slim build if it stopped importing from
the deferred module directly.
Closes gh-4793
This commit cleans up a few comments & configurations that are out of date
after the migration to ES modules backed by a Rollup-based compilation.
Also, de-indent AMD modules. This will preserve a more similar
structure to the one on 3.x-stable where the body of the main `define`
wrapper is not indented.
Closes gh-4705
So far, the slim build was expanded to its full exclusion list, generating the
following `jQuery.fn.jquery`:
```
v4.0.0-pre -ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-deprecated/ajax-event-alias,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready
```
This commit changes it to just `v4.0.0-pre slim`. Only the pure slim build is
treated this way, any modification to it goes through the old expansion; e.g.
for `custom:slim,-deprecated` we get the following `jQuery.fn.jquery`:
```
v4.0.0-pre -deprecated,-deprecated/ajax-event-alias,-deprecated/event,-ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready
```
Since the version string is also put in the jQuery header comment, it also got
smaller.
Also, the logic to skip including the commit hash in the header comment - when
provided through the COMMIT environment variable which we do in Jenkins - in
minified builds headers has been applied to builds with exclusions as well.
Closes gh-4649
So far, the slim build only excluded ajax & effects modules. As many web apps
right now rely on native Promises, often with a polyfill for legacy browsers,
deferred & callbacks modules are not that useful for sites that already exclude
ajax & effects modules.
This decreases the gzipped minified size of the slim module by 1760 bytes,
to 19706 bytes (below 20k!).
Closes gh-4553
This commit fixes unit tests for the following builds:
1. The no-deprecated build: `custom:-deprecated`
2. The current slim build: `custom:-ajax,-effects`
3. The future (#4553) slim build: `custom:-ajax,-callbacks,-deferred,-effects`
It also adds separate Travis jobs for the no-deprecated & slim builds.
Closes gh-4577
jQuery source has been migrated in gh-4541 from AMD to ES modules. To maintain
support for consumers of our AMD modules, this commits adds a task transpiling
the ES modules sources in `src/` to AMD in `amd/`.
A "Load with AMD" checkbox was also restored to the QUnit setup. Note that,
contrary to jQuery 3.x, AMD files need to be generated via `grunt amd` or
`grunt` as sources are not authored in ECMAScript modules. To achieve a similar
no-compile experience during jQuery 4.x testing, use the new "Load as modules"
checkbox which works in all supported browsers except for IE & Edge (the
legacy, EdgeHTML-based one).

Migrate all source AMD modules to ECMAScript modules. The final bundle
is compiled by a custom build process that uses Rollup under the hood.
Test files themselves are still loaded via RequireJS as that has to work in
IE 11.
Tests can now be run in "Load as modules" mode which replaces the previous
"Load with AMD" option. That option of running tests doesn't work in IE
and Edge as it requires support for dynamic imports.
Some of the changes required by the migration:
* check `typeof` of `noGlobal` instead of using the variable directly
as it's not available when modules are used
* change the nonce module to be an object as ECMASscript module exports
are immutable
* remove some unused exports
* import `./core/parseHTML.js` directly in `jquery.js` so that it's not
being cut out when the `ajax` module is excluded in a custom compilation
Closes gh-4541
So far, only browser-based JS files were required to be in strict mode (in the

This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The selector-native module has been removed. Further work on the selector
module may decrease the size enough that it will no longer be necessary. If
it turns out it's still useful, we'll reinstate it but the code will look
different anyway as we'll want to share as much code as possible with
the existing selector module.
The Sizzle AUTHORS.txt file has been merged with the jQuery one - people are
sorted by their first contributions to either of the two repositories.
The commit reduces the gzipped jQuery size by 1460 bytes compared to master.
Closes gh-4395
This commit requires all function parameters to be used, not just the last one.
In cases where that's not possible as we need to match an external API, there's
an escape hatch of prefixing an unused argument with `_`.
This change makes it easier to catch unused AMD dependencies and unused
parameters in internal functions the API of which we may change at will, among
other things.
Unused AMD dependencies have been removed as part of this commit.

The previous regex caused the final jQuery binary to have syntax errors for
var-modules with names starting with "return". For example, the following module

return function returnTrue() {
return true;
};
} );

So far, we've been testing that jQuery element iteration works with polyfilled
Symbol & transpiled for-of via a Node test with jsdom with the Symbol global

to an iframe test with transpiled JavaScript.
