+## Remembering what `atob` and `btoa` stand for
 
-### Remembering `atob` vs. `btoa`
+Base64 comes from IETF [RFC 4648](https://tools.ietf.org/html/rfc4648#section-4) (2006). 
 
-Here's a mnemonic that might be useful: if you have a plain string and want to base64 encode it, then decode it, `btoa` is what you run before (**b**efore - **b**toa), and `atob` is what you run after (**a**fter - **a**tob).
+- **`btoa`**, the encoder function, stands for **binary** to **ASCII**, meaning it converts any binary input into a subset of **ASCII** (Base64).
+- **`atob`**, the decoder function, converts **ASCII** (or Base64) to its original **binary** format.

+
+### Bug fixes
+
+Don't ignore period or 'e' characters after octal numbers.

+
+### Bug fixes
+
+Fix false positives in duplicated export name errors.
+
+## 4.0.0 (2016-08-07)
+
+### Breaking changes
+
+The default `ecmaVersion` option value is now 7.
+
+A number of internal method signatures changed, so plugins might need to be updated.
+
+### Bug fixes
+
+The parser now raises errors on duplicated export names.
+
+`arguments` and `eval` can now be used in shorthand properties.
+
+Duplicate parameter names in non-simple argument lists now always produce an error.

+
+Support for trailing commas in call expressions when `ecmaVersion` is >= 8.
+
+## 3.3.0 (2016-07-25)
+
+### Bug fixes
+
+Fix bug in tokenizing of regexp operator after a function declaration.
+

+Properly tokenize the division operator directly after a function expression.
+
+Allow trailing comma in destructuring arrays.

+
+### Fixes
+
+Allow update expressions as left-hand-side of the ES7 exponential operator.

+
+### Fixes
+
+Fix bug that accidentally made `undefined` a reserved word when parsing ES7.
+
+## 3.0.0 (2016-02-10)
+
+### Breaking changes
+
+The default value of the `ecmaVersion` option is now 6 (used to be 5).
+
+Support for comprehension syntax (which was dropped from the draft spec) has been removed.
+
+### Fixes
+
+`let` and `yield` are now “contextual keywords”, meaning you can mostly use them as identifiers in ES5 non-strict code.
+
+A parenthesized class or function expression after `export default` is now parsed correctly.
+

+When `ecmaVersion` is set to 7, Acorn will parse the exponentiation operator (`**`).
+
+The identifier character ranges are now based on Unicode 8.0.0.
+
+Plugins can now override the `raiseRecoverable` method to override the way non-critical errors are handled.
+
+## 2.7.0 (2016-01-04)
+
+### Fixes
+
+Stop allowing rest parameters in setters.
+
+Disallow `y` rexexp flag in ES5.
+
+Disallow `\00` and `\000` escapes in strict mode.
+
+Raise an error when an import name is a reserved word.
+
+## 2.6.2 (2015-11-10)
+
+### Fixes
+
+Don't crash when no options object is passed.
+
+## 2.6.0 (2015-11-09)
+
+### Fixes
+
+Add `await` as a reserved word in module sources.
+
+Disallow `yield` in a parameter default value for a generator.
+
+Forbid using a comma after a rest pattern in an array destructuring.
+
+### New features
+
+Support parsing stdin in command-line tool.
+
+## 2.5.0 (2015-10-27)
+
+### Fixes
+
+Fix tokenizer support in the command-line tool.
+
+Stop allowing `new.target` outside of functions.
+
+Remove legacy `guard` and `guardedHandler` properties from try nodes.
+
+Stop allowing multiple `__proto__` properties on an object literal in strict mode.
+
+Don't allow rest parameters to be non-identifier patterns.
+
+Check for duplicate paramter names in arrow functions.

+# Acorn
+
+A tiny, fast JavaScript parser written in JavaScript.
+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/acornjs/acorn/blob/master/acorn/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/acornjs/acorn/issues) or create pull
+requests on [github](https://github.com/acornjs/acorn). For questions
+and discussion, please use the
+[Tern discussion forum](https://discuss.ternjs.net).
+
+## Installation
+
+The easiest way to install acorn is from [`npm`](https://www.npmjs.com/):
+
+```sh
+npm install acorn
+```
+
+Alternately, you can download the source and build acorn yourself:
+
+```sh
+git clone https://github.com/acornjs/acorn.git
+cd acorn
+npm install
+```
+
+## Interface
+
+**parse**`(input, options)` is the main interface to the library. The
+`input` parameter is a string, `options` can be undefined or an object
+setting some of the options listed below. The return value will be an
+abstract syntax tree object as specified by the [ESTree
+spec](https://github.com/estree/estree).
+
+```javascript
+let acorn = require("acorn");
+console.log(acorn.parse("1 + 1"));
+```
+
+When encountering a syntax error, the parser will raise a
+`SyntaxError` object with a meaningful message. The error object will
+have a `pos` property that indicates the string offset at which the
+error occurred, and a `loc` object that contains a `{line, column}`
+object referring to that same position.
+
+Options can be provided by passing a second argument, which should be
+an object containing any of these fields:
+
+- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
+  either 3, 5, 6 (2015), 7 (2016), 8 (2017), 9 (2018), 10 (2019) or 11
+  (2020, partial support). This influences support for strict mode,
+  the set of reserved words, and support for new syntax features.
+  Default is 10.
+
+  **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
+  implemented by Acorn. Other proposed new features can be implemented
+  through plugins.
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+  either `"script"` or `"module"`. This influences global strict mode
+  and parsing of `import` and `export` declarations.
+
+  **NOTE**: If set to `"module"`, then static `import` / `export` syntax
+  will be valid, even if `ecmaVersion` is less than 6.
+
+- **onInsertedSemicolon**: If given a callback, that callback will be
+  called whenever a missing semicolon is inserted by the parser. The
+  callback will be given the character offset of the point where the
+  semicolon is inserted as argument, and if `locations` is on, also a
+  `{line, column}` object representing this position.
+
+- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
+  commas.
+
+- **allowReserved**: If `false`, using a reserved word will generate
+  an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
+  versions. When given the value `"never"`, reserved words and
+  keywords can also not be used as property names (as in Internet
+  Explorer's old parser).
+
+- **allowReturnOutsideFunction**: By default, a return statement at
+  the top level raises an error. Set this to `true` to accept such
+  code.
+
+- **allowImportExportEverywhere**: By default, `import` and `export`
+  declarations can only appear at a program's top level. Setting this
+  option to `true` allows them anywhere where a statement is allowed.
+  
+- **allowAwaitOutsideFunction**: By default, `await` expressions can
+  only appear inside `async` functions. Setting this option to
+  `true` allows to have top-level `await` expressions. They are
+  still not allowed in non-`async` functions, though.
+
+- **allowHashBang**: When this is enabled (off by default), if the
+  code starts with the characters `#!` (as in a shellscript), the
+  first line will be treated as a comment.
+
+- **locations**: When `true`, each node has a `loc` object attached
+  with `start` and `end` subobjects, each of which contains the
+  one-based line and zero-based column numbers in `{line, column}`
+  form. Default is `false`.
+
+- **onToken**: If a function is passed for this option, each found
+  token will be passed in same format as tokens returned from
+  `tokenizer().getToken()`.
+
+  If array is passed, each found token is pushed to it.
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **onComment**: If a function is passed for this option, whenever a
+  comment is encountered the function will be called with the
+  following parameters:
+
+  - `block`: `true` if the comment is a block comment, false if it
+    is a line comment.
+  - `text`: The content of the comment.
+  - `start`: Character offset of the start of the comment.
+  - `end`: Character offset of the end of the comment.
+
+  When the `locations` options is on, the `{line, column}` locations
+  of the comment’s start and end are passed as two additional
+  parameters.
+
+  If array is passed for this option, each found comment is pushed
+  to it as object in Esprima format:
+
+  ```javascript
+  {
+    "type": "Line" | "Block",
+    "value": "comment text",
+    "start": Number,
+    "end": Number,
+    // If `locations` option is on:
+    "loc": {
+      "start": {line: Number, column: Number}
+      "end": {line: Number, column: Number}
+    },
+    // If `ranges` option is on:
+    "range": [Number, Number]
+  }
+  ```
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **ranges**: Nodes have their start and end characters offsets
+  recorded in `start` and `end` properties (directly on the node,
+  rather than the `loc` object, which holds line/column data. To also
+  add a
+  [semi-standardized](https://bugzilla.mozilla.org/show_bug.cgi?id=745678)
+  `range` property holding a `[start, end]` array with the same
+  numbers, set the `ranges` option to `true`.
+
+- **program**: It is possible to parse multiple files into a single
+  AST by passing the tree produced by parsing the first file as the
+  `program` option in subsequent parses. This will add the toplevel
+  forms of the parsed file to the "Program" (top) node of an existing
+  parse tree.
+
+- **sourceFile**: When the `locations` option is `true`, you can pass
+  this option to add a `source` attribute in every node’s `loc`
+  object. Note that the contents of this option are not examined or
+  processed in any way; you are free to use whatever format you
+  choose.
+
+- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
+  will be added (regardless of the `location` option) directly to the
+  nodes, rather than the `loc` object.
+
+- **preserveParens**: If this option is `true`, parenthesized expressions
+  are represented by (non-standard) `ParenthesizedExpression` nodes
+  that have a single `expression` property containing the expression
+  inside parentheses.
+
+**parseExpressionAt**`(input, offset, options)` will parse a single
+expression in a string, and return its AST. It will not complain if
+there is more of the string left after the expression.
+
+**tokenizer**`(input, options)` returns an object with a `getToken`
+method that can be called repeatedly to get the next token, a `{start,
+end, type, value}` object (with added `loc` property when the
+`locations` option is enabled and `range` property when the `ranges`
+option is enabled). When the token's type is `tokTypes.eof`, you
+should stop calling the method, since it will keep returning that same
+token forever.
+
+In ES6 environment, returned result can be used as any other
+protocol-compliant iterable:
+
+```javascript
+for (let token of acorn.tokenizer(str)) {
+  // iterate over the tokens
+}
+
+// transform code to array of tokens:
+var tokens = [...acorn.tokenizer(str)];
+```
+
+**tokTypes** holds an object mapping names to the token type objects
+that end up in the `type` properties of tokens.
+
+**getLineInfo**`(input, offset)` can be used to get a `{line,
+column}` object for a given program string and offset.
+
+### The `Parser` class
+
+Instances of the **`Parser`** class contain all the state and logic
+that drives a parse. It has static methods `parse`,
+`parseExpressionAt`, and `tokenizer` that match the top-level
+functions by the same name.
+
+When extending the parser with plugins, you need to call these methods
+on the extended version of the class. To extend a parser with plugins,
+you can use its static `extend` method.
+
+```javascript
+var acorn = require("acorn");
+var jsx = require("acorn-jsx");
+var JSXParser = acorn.Parser.extend(jsx());
+JSXParser.parse("foo(<bar/>)");
+```
+
+The `extend` method takes any number of plugin values, and returns a
+new `Parser` class that includes the extra parser logic provided by
+the plugins.
+
+## Command line interface
+
+The `bin/acorn` utility can be used to parse a file from the command
+line. It accepts as arguments its input file and the following
+options:
+
+- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version
+  to parse. Default is version 9.
+
+- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
+
+- `--locations`: Attaches a "loc" object to each node with "start" and
+  "end" subobjects, each of which contains the one-based line and
+  zero-based column numbers in `{line, column}` form.
+
+- `--allow-hash-bang`: If the code starts with the characters #! (as
+  in a shellscript), the first line will be treated as a comment.
+
+- `--compact`: No whitespace is used in the AST output.
+
+- `--silent`: Do not output the AST, just return the exit status.
+
+- `--help`: Print the usage information and quit.
+
+The utility spits out the syntax tree as JSON data.

+## Ajv v7 beta is released
+
+[Ajv version 7.0.0-beta.0](https://github.com/ajv-validator/ajv/tree/v7-beta) is released with these changes:
+
+- to reduce the mistakes in JSON schemas and unexpected validation results, [strict mode](./docs/strict-mode.md) is added - it prohibits ignored or ambiguous JSON Schema elements.
+- to make code injection from untrusted schemas impossible, [code generation](./docs/codegen.md) is fully re-written to be safe.
+- to simplify Ajv extensions, the new keyword API that is used by pre-defined keywords is available to user-defined keywords - it is much easier to define any keywords now, especially with subschemas.
+- schemas are compiled to ES6 code (ES5 code generation is supported with an option).
+- to improve reliability and maintainability the code is migrated to TypeScript.
+
+**Please note**:
+
+- the support for JSON-Schema draft-04 is removed - if you have schemas using "id" attributes you have to replace them with "\$id" (or continue using version 6 that will be supported until 02/28/2021).
+- all formats are separated to ajv-formats package - they have to be explicitely added if you use them.
+
+See [release notes](https://github.com/ajv-validator/ajv/releases/tag/v7.0.0-beta.0) for the details.
+
+To install the new version:
+
+```bash
+npm install ajv@beta
+```
+
+See [Getting started with v7](https://github.com/ajv-validator/ajv/tree/v7-beta#usage) for code example.

+
+Ajv has been awarded a grant from Mozilla’s [Open Source Support (MOSS) program](https://www.mozilla.org/en-US/moss/) in the “Foundational Technology” track! It will sponsor the development of Ajv support of [JSON Schema version 2019-09](https://tools.ietf.org/html/draft-handrews-json-schema-02) and of [JSON Type Definition](https://tools.ietf.org/html/draft-ucarion-json-type-definition-04).
+
+Ajv also joined [OpenJS Foundation](https://openjsf.org/) – having this support will help ensure the longevity and stability of Ajv for all its users.
+
+This [blog post](https://www.poberezkin.com/posts/2020-08-14-ajv-json-validator-mozilla-open-source-grant-openjs-foundation.html) has more details.
+
+I am looking for the long term maintainers of Ajv – working with [ReadySet](https://www.thereadyset.co/), also sponsored by Mozilla, to establish clear guidelines for the role of a "maintainer" and the contribution standards, and to encourage a wider, more inclusive, contribution from the community.
+
+
 ## Please [sponsor Ajv development](https://github.com/sponsors/epoberezkin)
 
-I will get straight to the point - I need your support to ensure that the development of Ajv continues.
+Since I asked to support Ajv development 40 people and 6 organizations contributed via GitHub and OpenCollective - this support helped receiving the MOSS grant!
 
-I have developed Ajv for 5 years in my free time, but it is not  sustainable. I'd appreciate if you consider supporting its further development with donations:
+Your continuing support is very important - the funds will be used to develop and maintain Ajv once the next major version is released.
+
+Please sponsor Ajv via:
 - [GitHub sponsors page](https://github.com/sponsors/epoberezkin) (GitHub will match it)
 - [Ajv Open Collective️](https://opencollective.com/ajv)
 
-There are many small and large improvements that are long due, including the support of the next versions of JSON Schema specification, improving website and documentation, and making Ajv more modular and maintainable to address its limitations - what Ajv needs to evolve is much more than what I can contribute in my free time.
-
-I would also really appreciate any advice you could give on how to raise funds for Ajv development - whether some suitable open-source fund I could apply to or some sponsor I should approach.
-
-Since 2015 Ajv has become widely used, thanks to your help and contributions:
-

-- **5,000,000** dependent repositories on GitHub 🚀
-- **120,000,000** npm downloads per month! 💯

+## What's new in version 5.0
+
+clean-css 5.0 will introduce some breaking changes:
+
+* Node.js 6.x and 8.x are officially no longer supported;
+* `transform` callback in level-1 optimizations is removed in favor of new [plugins](#plugins) interface;
+* changes default Internet Explorer compatibility from 10+ to >11, to revert the old default use `{ compatibility: 'ie10' }` flag;
+* changes default `rebase` option from `true` to `false` so URLs are not rebased by default. Please note that if you set `rebaseTo` option it still counts as setting `rebase: true` to preserve some of the backward compatibility.
+
+And on the new features side of things:
+
+* format options now accepts numerical values for all breaks, which will allow you to have more control over output formatting, e.g. `format: {breaks: {afterComment: 2}}` means clean-css will add two line breaks after each comment
+* a new `batch` option (defaults to `false`) is added, when set to `true` it will process all inputs, given either as an array or a hash, without concatenating them.

+* allows filtering based on selector in `transform` callback, see [example](#how-to-apply-arbitrary-transformations-to-css-properties);
+* adds configurable line breaks via `format: { breakWith: 'lf' }` option.

+* `removeEmpty` flag in level 2 optimizations controlling removal of rules and nested blocks;
+* `compatibility: { selectors: { mergeLimit: <number> } }` flag in compatibility settings controlling maximum number of selectors in a single rule;
+* `minify` method improved signature accepting a list of hashes for a predictable traversal;
+* `selectorsSortingMethod` level 1 optimization allows `false` or `'none'` for disabling selector sorting;
+* `fetch` option controlling a function for handling remote requests;
+* new `font` shorthand and `font-*` longhand optimizers;
+* removal of `optimizeFont` flag in level 1 optimizations due to new `font` shorthand optimizer;
+* `skipProperties` flag in level 2 optimizations controlling which properties won't be optimized;

-## What's new in version 4.2
-
-clean-css 4.2 introduces the following changes / features:
-
-* Adds `process` method for compatibility with optimize-css-assets-webpack-plugin;
-* new `transition` property optimizer;
-* preserves any CSS content between `/* clean-css ignore:start */` and `/* clean-css ignore:end */` comments;
-* allows filtering based on selector in `transform` callback, see [example](#how-to-apply-arbitrary-transformations-to-css-properties);
-* adds configurable line breaks via `format: { breakWith: 'lf' }` option.
