+- Added `enableClientSidePolyfills` [option](https://github.com/csstools/postcss-plugins/tree/main/plugin-packs/postcss-preset-env#enableclientsidepolyfills) that allows you to control every single plugin that requires a browser library to fully work. Defaults to `true` so they're enabled by default.
+- Added `minimumVendorImplementations` [option](https://github.com/csstools/postcss-plugins/tree/main/plugin-packs/postcss-preset-env#minimumvendorimplementations) that allows you to enable/disable plugins based on their implementation status in browsers.

+- Updated `postcss-custom-properties` to `12.1.2` (patch)
+
+### 7.2.1 (January 12, 2022)
+
+- Always run plugins with side effects if certain options are set. [#140](https://github.com/csstools/postcss-plugins/issues/140)
+  - `custom-media-queries`
+  - `custom-properties`
+  - `environment-variables`

+
+This will ensure that CSS transforms that are not a browser polyfill are still applied.
+⚠️ A future major version `postcss-preset-env` will remove this behavior completely.
+
+### 7.2.0 (January 2, 2022)
+
+- Added warnings and useful messages when a feature that doesn't exist is configured. [156](https://github.com/csstools/postcss-preset-env/issues/156).
+
+When configured with these options for example: 
+
+```js
+options: {
+	features: {
+		"custom-media": true,
+		"postcss-logical": true,
+		"postcss-logica": true,
+	}
+}
+```
+
+It will yield the following warnings:
+
+```bash
+Unknown feature: "custom-media" did you mean: "custom-media-queries"
+Unknown feature: "postcss-logical" did you mean: "logical-properties-and-values"
+Unknown feature: "postcss-logica" did you mean: "logical-properties-and-values"

+
+- Moved browserslist detection from using each input file per process to using

+  If fixing this previously undocumented behavior causes any harm to existing
+  projects, it can be easily rolled back in a subsequent patch. For the
+  majority of projects — those with a singular browserslist configuration and
+  potentially many individually processed CSS files — we should expect reported

+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator and
+subsequent owner(s) (each and all, an “owner”) of an original work of
+authorship and/or a database (each, a “Work”).
+
+Certain owners wish to permanently relinquish those rights to a Work for the
+purpose of contributing to a commons of creative, cultural and scientific works
+(“Commons”) that the public can reliably and without fear of later claims of
+infringement build upon, modify, incorporate in other works, reuse and
+redistribute as freely as possible in any form whatsoever and for any purposes,
+including without limitation commercial purposes. These owners may contribute
+to the Commons to promote the ideal of a free culture and the further
+production of creative, cultural and scientific works, or to gain reputation or
+greater distribution for their Work in part through the use and efforts of
+others.
+
+For these and/or other purposes and motivations, and without any expectation of
+additional consideration or compensation, the person associating CC0 with a
+Work (the “Affirmer”), to the extent that he or she is an owner of Copyright
+and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and
+publicly distribute the Work under its terms, with knowledge of his or her
+Copyright and Related Rights in the Work and the meaning and intended legal
+effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+   protected by copyright and related or neighboring rights (“Copyright and
+   Related Rights”). Copyright and Related Rights include, but are not limited
+   to, the following:
+   1. the right to reproduce, adapt, distribute, perform, display, communicate,
+      and translate a Work;
+   2. moral rights retained by the original author(s) and/or performer(s);
+   3. publicity and privacy rights pertaining to a person’s image or likeness
+      depicted in a Work;
+   4. rights protecting against unfair competition in regards to a Work,
+      subject to the limitations in paragraph 4(i), below;
+   5. rights protecting the extraction, dissemination, use and reuse of data in
+      a Work;
+   6. database rights (such as those arising under Directive 96/9/EC of the
+      European Parliament and of the Council of 11 March 1996 on the legal
+      protection of databases, and under any national implementation thereof,
+      including any amended or successor version of such directive); and
+   7. other similar, equivalent or corresponding rights throughout the world
+      based on applicable law or treaty, and any national implementations
+      thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of,
+   applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
+   unconditionally waives, abandons, and surrenders all of Affirmer’s Copyright
+   and Related Rights and associated claims and causes of action, whether now
+   known or unknown (including existing as well as future claims and causes of

+   extensions), (iii) in any current or future medium and for any number of

+   makes the Waiver for the benefit of each member of the public at large and
+   to the detriment of Affirmer’s heirs and successors, fully intending that

+   termination, or any other legal or equitable action to disrupt the quiet
+   enjoyment of the Work by the public as contemplated by Affirmer’s express
+   Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be
+   judged legally invalid or ineffective under applicable law, then the Waiver
+   shall be preserved to the maximum extent permitted taking into account
+   Affirmer’s express Statement of Purpose. In addition, to the extent the
+   Waiver is so judged Affirmer hereby grants to each affected person a
+   royalty-free, non transferable, non sublicensable, non exclusive,
+   irrevocable and unconditional license to exercise Affirmer’s Copyright and
+   Related Rights in the Work (i) in all territories worldwide, (ii) for the

+   Work. Should any part of the License for any reason be judged legally
+   invalid or ineffective under applicable law, such partial invalidity or
+   ineffectiveness shall not invalidate the remainder of the License, and in
+   such case Affirmer hereby affirms that he or she will not (i) exercise any
+   of his or her remaining Copyright and Related Rights in the Work or (ii)
+   assert any associated claims and causes of action with respect to the Work,
+   in either case contrary to Affirmer’s express Statement of Purpose.

+
+[PostCSS Preset Env] lets you convert modern CSS into something most browsers
+can understand, determining the polyfills you need based on your targeted
+browsers or runtime environments.
+
+## Quick start
+
+[PostCSS Preset Env] is a [PostCSS] plugin.<br>
+If you are already using [PostCSS] to build your CSS, you can simply add [PostCSS Preset Env] to your configuration.
+
+- Install `postcss-preset-env` from npm.
+- Add `postcss-preset-env` to your configuration:
+
+```js
+const postcssPresetEnv = require('postcss-preset-env');
+
+const yourConfig = {
+	plugins: [
+		postcssPresetEnv(/* pluginOptions */)
+	]
+}
+```
+
+_[Read more on how to use and install PostCSS Preset Env.](#usage)_
+
+## How does it work?
+
+[PostCSS Preset Env] is a Plugin Pack for [PostCSS]. It leverages the list of the features we keep an eye from [CSSDB][cssdb] and applies plugins, so you can use those new features without having to worry about browser support.
+
+CSSDB exposes the browser support that each feature has which can come from [Can I Use](https://caniuse.com/css-all) or from [MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/all) (through [mdn/browser-compat-data](https://github.com/mdn/browser-compat-data)).
+
+By providing a list of browser targets for your project, plugins that aren't needed will be skipped. Over time your targets might change and by updating the settings your CSS bundle will only ever contain the needed fallbacks.
+
+What [PostCSS Preset Env] does is to take the support data that comes from MDN and Can I Use and determine from a [browserlist](https://github.com/browserslist/browserslist) whether those transformations are needed. It also packs [Autoprefixer](https://github.com/postcss/autoprefixer) within and shares the list with it, so prefixes are only applied when you're going to need them given your browser support list.
+
+### Glossary:
+
+* **Browser list option**: [Browserlist](https://github.com/browserslist/browserslist) is a package that gives you a list of browsers for a given query. For example, `chrome < 42` will give you a list of every Chrome version that has been released up to, but not including, 42.
+* **Browser support stats**: Features get introduced on browsers at certain versions. They're often visible on [MDN](https://developer.mozilla.org/en-US/) and [Can I Use](https://caniuse.com/). Comparing these stats with the needed _support_ for your project tells you if it's safe to use a feature or not.
+* **CSS Feature**: A CSS feature is often part of some spec that enables a specific feature. For example, `hwb` functional notation lets you express a given color according to its hue, whiteness, and blackness. This is part of the CSS Color 4 Spec.
+* **CSS Spec**: A Spec is a document that collects new features, what problems are they trying to solve and how it's intended to be solved (generally). This is usually an evolving document that goes over lengthy discussions between several people from different companies.
+* **Plugin**: A plugin is package that's intended (usually) to enable a new CSS Feature by leveraging PostCSS. This doesn't need to be part of any spec. An example of the latter is [PostCSS Mixins](https://github.com/postcss/postcss-mixins), a concept that existed on Less or Sass, but it's not part of any spec. This plugin plack **only** packs plugins that enable features acknowledged by the World Wide Web Consortium (W3C) which will then be implemented by browsers later.
+* **Polyfill**: A polyfill is a piece of code (usually JavaScript on the Web) used to provide modern functionality on older browsers that do not natively support it. A polyfill _should_ be indistinguishable from the native behaviour.
+
+Here's a quick example of the syntax you can leverage by using [PostCSS Preset Env].
+
+```pcss
+@custom-media --viewport-medium (width <= 50rem);
+@custom-selector :--heading h1, h2, h3, h4, h5, h6;
+
+:root {
+  --mainColor: #12345678;
+}
+
+body {
+  color: var(--mainColor);
+  font-family: system-ui;
+  overflow-wrap: break-word;
+}
+
+:--heading {
+  background-image: image-set(url(img/heading.png) 1x, url(img/heading@2x.png) 2x);
+
+  @media (--viewport-medium) {
+    margin-block: 0;
+  }
+}
+
+a {
+  color: rgb(0 0 100% / 90%);
+
+  &:hover {
+    color: rebeccapurple;
+  }
+}
+
+/* becomes */
+
+:root {
+  --mainColor: rgba(18, 52, 86, 0.47059);
+}
+
+body {
+  color: rgba(18, 52, 86, 0.47059);
+  color: var(--mainColor);
+  font-family: system-ui, -apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Oxygen, Ubuntu, Cantarell, Droid Sans, Helvetica Neue;
+  word-wrap: break-word;
+}
+
+h1, h2, h3, h4, h5, h6 {
+  background-image: url(img/heading.png);
+}
+
+@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) {
+  h1, h2, h3, h4, h5, h6 {
+    background-image: url(img/heading@2x.png)
+  }
+}
+
+@media (max-width: 50rem) {
+  h1, h2, h3, h4, h5, h6 {
+    margin-top: 0;
+    margin-bottom: 0;
+  }
+}
+
+a {
+  color: rgba(0, 0, 255, 0.9)
+}
+
+a:hover {
+  color: #639;
+}
+```
+
+Without any configuration options, [PostCSS Preset Env] enables **Stage 2**
+features and supports **all** browsers.

+[![Style with Preset Env][readme-style-with-preset-env-img]][readme-style-with-preset-env-url]
+
+⚠️ Please note that some features need a companion library that makes 
+the feature work. While we try to avoid this requirement, there are instances
+in which this isn't possible to polyfill a new behaviour with _just_ CSS.
+
+[See the list below](#plugins-that-need-client-library).
+
+## Usage
+
+Add [PostCSS Preset Env] to your project:
+
+```bash
+npm install postcss-preset-env --save-dev
+```
+
+Use [PostCSS Preset Env] as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssPresetEnv = require('postcss-preset-env');
+
+postcss([
+  postcssPresetEnv(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Preset Env] runs in all Node environments, with special instructions for:

+## Options
+
+### stage
+
+The `stage` option determines which CSS features to polyfill, based upon their
+stability in the process of becoming implemented web standards.
+
+```js
+postcssPresetEnv({ stage: 0 })
+```
+
+The `stage` can be `0` (experimental) through `4` (stable), or `false`. Setting
+`stage` to `false` will disable every polyfill. Doing this would only be useful
+if you intended to exclusively use the [`features`](#features) option.
+
+Default: `2`
+
+### minimumVendorImplementations
+
+The `minimumVendorImplementations` option determines which CSS features to polyfill, based their implementation status.
+This can be used to enable plugins that are available in browsers regardless of the [spec status](#stage).
+
+```js
+postcssPresetEnv({ minimumVendorImplementations: 2 })
+```
+
+`minimumVendorImplementations` can be `0` (no vendor has implemented it) through `3` (all major vendors).<br>
+
+Default: `0`
+
+**Note:**
+
+When a feature has not yet been implemented by any vendor it can be considered experimental.<br>
+Even with a single implementation it might still change in the future.<br>
+Sometimes issues with a feature/specification are only discovered after it becomes available.
+
+A value of `2` is recommended when you want to use only those features that should be [stable](#stability-and-portability).
+
+Having 2 independent implementations is [a critical step in proposals becoming standards](https://www.w3.org/2021/Process-20211102/#implementation-experience) and a good indicator of a feature's stability.
+
+### features
+
+The `features` option enables or disables specific polyfills by ID. Passing
+`true` to a specific feature ID will enable its polyfill, while passing `false`
+will disable it. [List of Features](https://github.com/csstools/postcss-plugins/blob/main/plugin-packs/postcss-preset-env/FEATURES.md)
+
+```js
+postcssPresetEnv({
+  /* use stage 3 features + css nesting rules */
+  stage: 3,
+  features: {
+    'nesting-rules': true
+  }
+})
+```
+
+Passing an object to a specific feature ID will both enable and configure it.
+
+```js
+postcssPresetEnv({
+  /* use stage 3 features + css color-mod (warning on unresolved) */
+  stage: 3,
+  features: {
+    'color-mod-function': { unresolved: 'warn' }
+  }
+})
+```
+
+Any polyfills not explicitly enabled or disabled through `features` are
+determined by the [`stage`](#stage) option.
+
+### browsers
+
+The `browsers` option determines which polyfills are required based upon the
+browsers you are supporting.
+
+[PostCSS Preset Env] supports any standard [browserslist] configuration, which
+can be a `.browserslistrc` file, a `browserslist` key in `package.json`, or
+`browserslist` environment variables.
+
+The `browsers` option should only be used when a standard browserslist
+configuration is not available.
+
+```js
+postcssPresetEnv({ browsers: 'last 2 versions' })
+```
+
+If no valid browserslist configuration is specified, the
+[default browserslist query](https://github.com/browserslist/browserslist#queries)
+will be used.
+
+### insertBefore / insertAfter
+
+The `insertBefore` and `insertAfter` keys allow you to insert other PostCSS
+plugins into the chain. This is only useful if you are also using sugary
+PostCSS plugins that must execute before or after certain polyfills.
+Both `insertBefore` and `insertAfter` support chaining one or multiple plugins.
+
+```js
+import postcssSimpleVars from 'postcss-simple-vars';
+
+postcssPresetEnv({
+  insertBefore: {
+    'all-property': postcssSimpleVars
+  }
+})
+```
+
+### autoprefixer
+
+[PostCSS Preset Env] includes [autoprefixer] and [`browsers`](#browsers) option
+will be passed to it automatically.
+
+Specifying the `autoprefixer` option enables passing
+[additional options](https://github.com/postcss/autoprefixer#options)
+into [autoprefixer].
+
+```js
+postcssPresetEnv({
+  autoprefixer: { grid: true }
+})
+```
+
+Passing `autoprefixer: false` disables autoprefixer.
+
+⚠️ [autoprefixer] has [complex logic to fix CSS Grid in IE and older Edge](https://github.com/postcss/autoprefixer#grid-autoplacement-support-in-ie).
+
+This can have unexpected results with certain features and when [`preserve: true`](#preserve) is used. (defaults to `true`)
+
+```pcss
+:root {
+  --grid-gap: 15px;
+}
+
+.test-grid {
+	grid-gap: var(--grid-gap);
+	grid-template-columns: repeat(2, 1fr);
+}
+```
+
+Becomes :
+
+```
+.test-grid {
+	grid-gap: 15px;
+	grid-gap: var(--grid-gap);
+	-ms-grid-columns: 1fr var(--grid-gap) 1fr;
+	grid-template-columns: repeat(2, 1fr);
+}
+```
+
+The prefixed `-ms-grid-columns` still has a custom property: `1fr var(--grid-gap) 1fr;` which won't work.<br />
+This example shows issues with custom properties but other transforms might have similar issues.
+
+If you target IE or older Edge it is best to avoid using other modern features in grid property values.<br />
+As a last resort you can set [`preserve: false`](#preserve), we do not advice this as doing so purely to fix issues with CSS grid.
+
+_older Edge is any version before chromium (<79)_
+
+### preserve
+
+The `preserve` option determines whether all plugins should receive a
+`preserve` option, which may preserve or remove otherwise-polyfilled CSS. By
+default, this option is not configured.
+
+```js
+postcssPresetEnv({
+  preserve: false // instruct all plugins to omit pre-polyfilled CSS
+});
+```
+
+### importFrom
+
+The `importFrom` option specifies sources where variables like Custom Media,
+Custom Properties, Custom Selectors, and Environment Variables can be imported
+from, which might be CSS, JS, and JSON files, functions, and directly passed
+objects.
+
+```js
+postcssPresetEnv({
+  /*
+    @custom-media --small-viewport (max-width: 30em);
+    @custom-selector :--heading h1, h2, h3;
+    :root { --color: red; }
+  */
+  importFrom: 'path/to/file.css'
+});
+```
+
+Multiple sources can be passed into this option, and they will be parsed in the
+order they are received. JavaScript files, JSON files, functions, and objects
+will use different namespaces to import different kinds of variables.
+
+```js
+postcssPresetEnv({
+  importFrom: [
+    /*
+      @custom-media --small-viewport (max-width: 30em);
+      @custom-selector :--heading h1, h2, h3;
+      :root { --color: red; }
+    */
+    'path/to/file.css',
+
+    /* module.exports = {
+      customMedia: { '--small-viewport': '(max-width: 30em)' },
+      customProperties: { '--color': 'red' },
+      customSelectors: { ':--heading': 'h1, h2, h3' },
+      environmentVariables: { '--branding-padding': '20px' }
+    } */
+    'and/then/this.js',
+
+    /* {
+      "custom-media": { "--small-viewport": "(max-width: 30em)" }
+      "custom-properties": { "--color": "red" },
+      "custom-selectors": { ":--heading": "h1, h2, h3" },
+      "environment-variables": { "--branding-padding": "20px" }
+    } */
+    'and/then/that.json',
+
+    {
+      customMedia: { '--small-viewport': '(max-width: 30em)' },
+      customProperties: { '--color': 'red' },
+      customSelectors: { ':--heading': 'h1, h2, h3' },
+      environmentVariables: { '--branding-padding': '20px' }
+    },
+    () => {
+      const customMedia = { '--small-viewport': '(max-width: 30em)' };
+      const customProperties = { '--color': 'red' };
+      const customSelectors = { ':--heading': 'h1, h2, h3' };
+      const environmentVariables = { '--branding-padding': '20px' };
+
+      return { customMedia, customProperties, customSelectors, environmentVariables };
+    }
+  ]
+});
+```
+
+### exportTo
+
+The `exportTo` option specifies destinations where variables like Custom Media,
+Custom Properties, Custom Selectors, and Environment Variables can be exported
+to, which might be CSS, JS, and JSON files, functions, and directly passed
+objects.
+
+```js
+postcssPresetEnv({
+  /*
+    @custom-media --small-viewport (max-width: 30em);
+    @custom-selector :--heading h1, h2, h3;
+    :root { --color: red; }
+  */
+  exportTo: 'path/to/file.css'
+});
+```
+
+Multiple destinations can be passed into this option as well, and they will be
+parsed in the order they are received. JavaScript files, JSON files, and
+objects will use different namespaces to import different kinds of variables.
+
+```js
+const cachedObject = {};
+
+postcssPresetEnv({
+  exportTo: [
+    /*
+      @custom-media --small-viewport (max-width: 30em);
+      @custom-selector :--heading h1, h2, h3;
+      :root { --color: red; }
+    */
+    'path/to/file.css',
+
+    /* module.exports = {
+      customMedia: { '--small-viewport': '(max-width: 30em)' },
+      customProperties: { '--color': 'red' },
+      customSelectors: { ':--heading': 'h1, h2, h3' },
+      environmentVariables: { '--branding-padding': '20px' }
+    } */
+    'and/then/this.js',
+
+    /* {
+      "custom-media": { "--small-viewport": "(max-width: 30em)" }
+      "custom-properties": { "--color": "red" },
+      "custom-selectors": { ":--heading": "h1, h2, h3" },
+      "environment-variables": { "--branding-padding": "20px" }
+    } */
+    'and/then/that.json',
+
+    cachedObject,
+    variables => {
+      if ('customProperties' in variables) {
+        // do something special with customProperties
+      }
+
+      Object.assign(cachedObject, variables);
+    }
+  ]
+});
+```
+
+### debug
+
+The `debug` option enables debugging messages to stdout which should be useful to help you debug which features have been enabled/disabled and why.
+
+### enableClientSidePolyfills
+
+The `enableClientSidePolyfills` enables any feature that would need an extra browser library to be loaded into the page for it to work. Defaults to `true`.
+
+Note that manually enabling/disabling features via the "feature" option overrides this flag.
+
+## Stability and Portability
+
+[PostCSS Preset Env] will often include very modern CSS features that are not fully ready yet.
+This gives users the chance to play around with these features and provide feedback.
+
+If the specification changes or is abandoned a new major version of the plugin will be released.
+This will require you to update your source code so that everything works as expected.
+
+To have more stability between updates of [PostCSS Preset Env] you may set `stage: 3` and/or `minimumVendorImplementations: 2`.
+
+A side effect of staying close to the standard is that you can more easily migrate your project to other tooling all together.
+
