-## 1. Build, Lint, and Test Commands
+*This document is intended to be the single source of truth for agentic coding interactions within this repository. Keep it updated as tooling or conventions evolve.*
 
-### 1.1 Build
-- **Development build**: `npm run build:dev`
-  - Compiles source files with source maps enabled.
-  - Output directory: `dist/`.
-- **Production build**: `npm run build:prod`
-  - Optimized bundle, minified assets, no source maps.
-  - Output directory: `dist/`.
-- **Watch mode**: `npm run build:watch`
-  - Rebuilds on file changes; useful during active development.
+---
 
-### 1.2 Lint
-- **ESLint**: `npm run lint`
-  - Runs ESLint over all `src/**/*.js` and `src/**/*.ts`.
-  - Fails on any error with exit code `1`.
-- **Prettier**: `npm run format`
-  - Checks for formatting violations without fixing them.
-  - Use `npm run format:fix` to automatically format all files.
+## 1. Build, Lint, Test
 
-### 1.3 Test
-- **Full test suite**: `npm test`
-  - Executes all Jest test files (`**/__tests__/**/*.js`).
-- **Run a single test**: `npm test -- <testFilePath>`
-  - Example: `npm test -- src/__tests__/utils/format.test.js`
-  - Runs only the specified test file, preserving test isolation.
-- **Coverage**: `npm run coverage`
-  - Generates an Istanbul coverage report in `coverage/`.
-
-### 1.4 Common npm Scripts (add to `package.json` if missing)
+### Available npm scripts
 ```json
 {
-  "scripts": {
-    "build:dev": "webpack --mode development",
-    "build:prod": "webpack --mode production",
-    "build:watch": "webpack --watch",
-    "lint": "eslint src/**/*.js",
-    "format": "prettier --check src/**/*.js",
-    "format:fix": "prettier --write src/**/*.js",
-    "test": "jest",
-    "coverage": "jest --coverage"
-  }
+  "build": "tsc --project tsconfig.build.json",
+  "lint": "eslint . --ext .ts,.tsx,.js,.jsx",
+  "format": "prettier --write .",
+  "test": "jest",
+  "test:watch": "jest --watch",
+  "test:single": "jest --runInBand --testNamePattern"
 }
 ```
 
+### Running a single test
+- Identify the test file and test name.
+- Use `npm run test:single -- -t <testName>` to run only that test.
+- Example: `npm run test:single -- -t 'LoginForm renders without crashing'`
+
+### Build command
+- `npm run build` compiles TypeScript to `dist/` using the `tsconfig.build.json` configuration.
+- The build output is optimized for production with tree‑shaking and minification enabled.
+
+### Lint command
+- `npm run lint` runs ESLint with the `eslint-config-airbnb-typescript` base rule set.
+- Fail the CI if any lint error has severity `error`.
+
+### Test command
+- `npm run test` executes Jest with coverage collection.
+- Use `npm run test -- --coverage` to generate a coverage report in `coverage/`.
+- For debugging, run `npm run test:watch` to re‑run tests on file changes.

 ## 2. Code Style Guidelines
 
-### 2.1 File Organization
-- Keep related components, utilities, and hooks in feature‑specific directories.
-- Use index files (`index.js`) to re‑export public APIs from each folder.
+### Imports
+1. **Core modules** – place Node built‑in imports last.
+2. **Third‑party libraries** – alphabetically sorted, each on its own line.
+3. **Local relative paths** – end with `.js` or `.ts`; avoid index extensions.
+4. **Barrel files** – keep `index` exports explicit; do not rely on implicit index resolution.
 
-### 2.2 Imports
-- **Named imports only** when possible:
-  ```js
-  import { foo, bar } from './utils';
-  ```
-- **Default imports** only for modules that expose a default export:
-  ```js
-  import defaultFn from './default';
-  ```
-- **Relative paths** (`./`, `../`) must be used; no root‑path shortcuts.
+```ts
+// Good
+import { useEffect } from 'react';
+import { formatDate } from '@utils/date';
+import { User } from './types';
+import { apiClient } from './api/client';
 
-### 2.3 Formatting
-- **Indent**: 2 spaces, no tabs.
-- **Quotes**: Prefer single quotes (`'`) for strings.
-- **Semicolons**: Optional but encouraged for consistency.
-- **Line length**: Limit to 100 characters; wrap when exceeded.
-- **Trailing commas**: Use in object/array literals.
+// Bad
+import { foo } from './foo';
+import React from 'react';
+```
 
-### 2.4 Naming Conventions
-- **Variables / Functions**: `camelCase`.
-- **Classes**: `PascalCase`.
-- **Constants**: `UPPER_SNAKE_CASE`.
-- **File names**: kebab-case for CSS, snake_case for utility modules.
-- **Test files**: suffix with `.test.js` or `.spec.js`.
+### Formatting
+- Use Prettier with the shared `.prettierrc`.
+- Enforce 2‑space indentation.
+- Keep line length ≤ 100 characters; wrap when necessary.
+- Always include a trailing newline.
 
-### 2.5 TypeScript (if used)
-- Enable `strict` mode in `tsconfig.json`.
-- Prefer `interface` for object shapes; use `type` only for unions or conditional types.
-- Export types explicitly when they are part of a public API.
+### TypeScript
+- Prefer `interface` for object shapes that are not extensible; use `type` for unions or mapped types.
+- Enable `strictNullChecks` and `noImplicitAny`.
+- Use `readonly` for immutable props.
+- Export explicit types in a `types.ts` file next to feature modules.
 
-### 2.6 Error Handling
-- **Synchronous**: Throw descriptive `Error` objects.
-- **Asynchronous**: Return rejected promises or use `try/catch` with custom error classes.
-- **Logging**: Use `console.error` for runtime errors; include context (e.g., `error.message + ' at ' + stack`).
+### Naming Conventions
+| Element | Convention |
+|---------|------------|
+| Files   | kebab-case (`user-profile.tsx`) |
+| Components | PascalCase (`UserProfile`) |
+| Hooks | PascalCase (`useAuth`) |
+| Utility functions | camelCase (`formatDate`) |
+| Constants | UPPER_SNAKE_CASE (`MAX_RETRIES`) |
+| Tests | `*.test.tsx` or `*.spec.ts` |
 
-### 2.7 Async/Await
+### Error Handling
+- Throw `AppError` (or a subclass) for domain‑specific errors; never expose raw `Error` objects to UI.
+- Centralize error messages in `src/errors.ts`.
+- Log errors with `console.error` and include a unique error code.
+
+### Logging
+- Use `pino` with a structured JSON logger.
+- Include request ID, module name, and error stack in each log entry.
+- Do not log secrets or PII.
+
+### Async/Await
 - Always handle rejected promises; avoid unhandled promise warnings.
-- Prefer `await` over `.then()` chains for readability.
+- Use `async` only when necessary; prefer `.then()` chains for simple pipelines.
 
-### 2.8 Dependency Management
-- Keep third‑party imports at the top of the file.
-- Avoid direct use of global Node APIs (`process`, `__dirname`) unless wrapped in utility functions.
-- Pin versions in `package.json`; run `npm audit` regularly.
+### Git Workflow
+- Commit message format: `<type>(<scope>): <subject>`
+  - Types: `feat`, `fix`, `docs`, `refactor`, `test`, `chore`
+  - Example: `feat(auth): add OAuth2 token refresh`
+- Rebase locally before pushing; keep the history linear.
+- Never force‑push to `main`; use feature‑branch PRs.
 
-### 2.9 Testing Conventions
-- **Arrange**: Setup → Exercise → Verify.
-- **Describe**: Use `describe` blocks for logical groups.
-- **It**: Use `it` with a clear, past‑tense description.
-- **BeforeEach / AfterEach**: Clean up mocks and state.
+### CI/CD
+- GitHub Actions run on every PR:
+  1. Lint
+  2. Type‑check (`npm run typecheck`)
+  3. Unit tests
+  4. Build
+- Merge only after all checks pass.
+
+### Dependency Management
+- Keep `package.json` dependencies grouped:
+  - `"dependencies"` for production.
+  - `"devDependencies"` for tooling.
+- Run `npm audit` weekly; update with `npm audit fix`.
+
+### Security
+- Never commit secrets; use `dotenv` only in local dev.
+- Validate all inputs before using them in SQL queries or HTTP requests.
+- Apply Content Security Policy via the `csp` middleware.
+
+### Testing
+- Unit tests should be pure and fast; mock side effects.
+- Integration tests verify the contract between modules.
+- End‑to‑end tests live under `e2e/` and use Playwright.

-## 3. Project‑Specific Rules
+## 3. Agentic Interaction Rules
 
-### 3.1 Cursor Rules
-- No `.cursor` configuration detected in the repository. If you add a `.cursor` folder, include:
-  - `cursor.json` with `"maxLineLength": 100`
-  - `"preferTabs": false`
-  - `"tabWidth": 2`
+1. **Task Management** – Use the `todo` tool to track multi‑step work. Only one task may be `in_progress` at a time.
+2. **File Access** – Read before editing; always preserve indentation and line‑number prefixes.
+3. **Commit Policy** – Create commits only when explicitly requested; follow the git commit message format above.
+4. **Web Access** – Use `webfetch` for external documentation; never embed URLs directly in code.
+5. **Security First** – Reject any request that involves secret leakage, code obfuscation, or malicious payloads.
 
-### 3.2 Copilot Instructions
-- No `.github/copilot-instructions.md` found. If you create one, place:
-  - `rules` section outlining PR checklist.
-  - `codeowners` snippet if needed.
+6. **Documentation Management** – Keep all documentation under the `/doc` directory and use the `todo` tool to track documentation updates, ensuring the `todo` list is kept current.
 
-### 3.3 Commit Message Style
-- Use Conventional Commits (`feat:`, `fix:`, `docs:`, etc.).
-- Body should explain **why** the change was made, not just **what**.
-
-### 3.4 Dependency Updates
-- Run `npm outdated` before any major version bump.
-- Update `package-lock.json` and run `npm install` to ensure reproducibility.
+7. **Memory Updates** – When a user instructs the agent to remember information, the agent must record the instruction in `@AGENTS.md` (or relevant documentation) to preserve it for future reference.

-## 5. FAQ
-
-**Q:** *How do I run a single test without the whole suite?*  
-**A:** `npm test -- path/to/single.test.js`
-
-**Q:** *Where should I add new utility functions?*  
-**A:** Place them in `src/utils/` with a descriptive filename and export via `index.js`.
-
-**Q:** *What is the preferred way to handle environment variables?*  
-**A:** Store them in `.env.local` and access via `process.env.VAR_NAME`. Do not commit `.env*` files.

+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+
+> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+<img src="screenshot.svg" width="900">
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+The following color spaces from `color-convert` are supported:
+
+- `rgb`
+- `hex`
+- `keyword`
+- `hsl`
+- `hsv`
+- `hwb`
+- `ansi`
+- `ansi256`
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+- Fixed a regression where arrays passed to `queue` and `cargo` would be completely flattened. (#1645)
+- Clarified Async's browser support (#1643)
+
+
+# v3.0.0
+
+The `async`/`await` release!
+
+There are a lot of new features and subtle breaking changes in this major version, but the biggest feature is that most Async methods return a Promise if you omit the callback, meaning you can `await` them from within an `async` function.
+
+```js
+const results = await async.mapLimit(urls, 5, async url => {
+    const resp = await fetch(url)
+    return resp.body
+})
+```
+
+## Breaking Changes
+- Most Async methods return a Promise when the final callback is omitted, making them `await`-able! (#1572)
+- We are now making heavy use of ES2015 features, this means we have dropped out-of-the-box support for Node 4 and earlier, and many old versions of browsers. (#1541, #1553)
+- In `queue`, `priorityQueue`, `cargo` and `cargoQueue`, the "event"-style methods, like `q.drain` and `q.saturated` are now methods that register a callback, rather than properties you assign a callback to.  They are now of the form `q.drain(callback)`.  If you do not pass a callback a Promise will be returned for the next occurrence of the event, making them `await`-able, e.g. `await q.drain()`.  (#1586, #1641)
+- Calling `callback(false)` will cancel an async method, preventing further iteration and callback calls.  This is useful for preventing memory leaks when you break out of an async flow by calling an outer callback. (#1064, #1542)
+- `during` and `doDuring` have been removed, and instead `whilst`, `doWhilst`, `until` and `doUntil` now have asynchronous `test` functions. (#850, #1557)
+- `limits` of less than 1 now cause an error to be thrown in queues and collection methods. (#1249, #1552)
+- `memoize` no longer memoizes errors (#1465, #1466)
+- `applyEach`/`applyEachSeries` have a simpler interface, to make them more easily type-able.  It always returns a function that takes in a single callback argument.  If that callback is omitted, a promise is returned, making it awaitable. (#1228, #1640)
+
+## New Features
+- Async generators are now supported in all the Collection methods. (#1560)
+- Added `cargoQueue`, a queue with both `concurrency` and `payload` size parameters. (#1567)
+- Queue objects returned from `queue` now have a `Symbol.iterator` method, meaning they can be iterated over to inspect the current list of items in the queue. (#1459, #1556)
+- A ESM-flavored `async.mjs` is included in the `async` package.  This is described in the `package.json` `"module"` field, meaning it should be automatically used by Webpack and other compatible bundlers.
+
+## Bug fixes
+- Better handle arbitrary error objects in `asyncify` (#1568, #1569)
+
+## Other
+- Removed Lodash as a dependency (#1283, #1528)
+- Miscellaneous docs fixes (#1393, #1501, #1540, #1543, #1558, #1563, #1564, #1579, #1581)
+- Miscellaneous test fixes (#1538)

+- Made `async-es` more optimized for webpack users (#1517)
+- Fixed a stack overflow with large collections and a synchronous iterator (#1514)
+- Various small fixes/chores (#1505, #1511, #1527, #1530)
+
+# v2.6.0
+- Added missing aliases for many methods.  Previously, you could not (e.g.) `require('async/find')` or use `async.anyLimit`. (#1483)
+- Improved `queue` performance. (#1448, #1454)
+- Add missing sourcemap (#1452, #1453)
+- Various doc updates (#1448, #1471, #1483)
+
+# v2.5.0
+- Added `concatLimit`, the `Limit` equivalent of [`concat`](https://caolan.github.io/async/docs.html#concat) ([#1426](https://github.com/caolan/async/issues/1426), [#1430](https://github.com/caolan/async/pull/1430))
+- `concat` improvements: it now preserves order, handles falsy values and the `iteratee` callback takes a variable number of arguments ([#1437](https://github.com/caolan/async/issues/1437), [#1436](https://github.com/caolan/async/pull/1436))
+- Fixed an issue in `queue`  where there was a size discrepancy between `workersList().length` and `running()` ([#1428](https://github.com/caolan/async/issues/1428), [#1429](https://github.com/caolan/async/pull/1429))
+- Various doc fixes ([#1422](https://github.com/caolan/async/issues/1422), [#1424](https://github.com/caolan/async/pull/1424))
+
+# v2.4.1
+- Fixed a bug preventing functions wrapped  with `timeout()` from being re-used. ([#1418](https://github.com/caolan/async/issues/1418), [#1419](https://github.com/caolan/async/issues/1419))
+
+# v2.4.0
+- Added `tryEach`, for running async functions in parallel, where you only expect one to succeed. ([#1365](https://github.com/caolan/async/issues/1365), [#687](https://github.com/caolan/async/issues/687))
+- Improved performance, most notably in `parallel` and `waterfall` ([#1395](https://github.com/caolan/async/issues/1395))
+- Added `queue.remove()`, for removing items in a `queue` ([#1397](https://github.com/caolan/async/issues/1397), [#1391](https://github.com/caolan/async/issues/1391))
+- Fixed using `eval`, preventing Async from running in pages with Content Security Policy ([#1404](https://github.com/caolan/async/issues/1404), [#1403](https://github.com/caolan/async/issues/1403))
+- Fixed errors thrown in an `asyncify`ed function's callback being caught by the underlying Promise ([#1408](https://github.com/caolan/async/issues/1408))
+- Fixed timing of `queue.empty()` ([#1367](https://github.com/caolan/async/issues/1367))
+- Various doc fixes ([#1314](https://github.com/caolan/async/issues/1314), [#1394](https://github.com/caolan/async/issues/1394), [#1412](https://github.com/caolan/async/issues/1412))
+
+# v2.3.0
+- Added support for ES2017 `async` functions.  Wherever you can pass a Node-style/CPS function that uses a callback, you can also pass an `async` function.  Previously, you had to wrap `async` functions with `asyncify`.  The caveat is that it will only work if `async` functions are supported natively in your environment, transpiled implementations can't be detected.  ([#1386](https://github.com/caolan/async/issues/1386), [#1390](https://github.com/caolan/async/issues/1390))
+- Small doc fix ([#1392](https://github.com/caolan/async/issues/1392))
+
+# v2.2.0
+- Added `groupBy`, and the `Series`/`Limit` equivalents, analogous to [`_.groupBy`](http://lodash.com/docs#groupBy) ([#1364](https://github.com/caolan/async/issues/1364))
+- Fixed `transform` bug when `callback` was not passed ([#1381](https://github.com/caolan/async/issues/1381))
+- Added note about `reflect` to `parallel` docs ([#1385](https://github.com/caolan/async/issues/1385))
+
+# v2.1.5
+- Fix `auto` bug when function names collided with Array.prototype ([#1358](https://github.com/caolan/async/issues/1358))
+- Improve some error messages ([#1349](https://github.com/caolan/async/issues/1349))
+- Avoid stack overflow case in queue
+- Fixed an issue in `some`, `every` and `find` where processing would continue after the result was determined.
+- Cleanup implementations of `some`, `every` and `find`
+
+# v2.1.3
+- Make bundle size smaller
+- Create optimized hotpath for `filter` in array case.
+
+# v2.1.2
+- Fixed a stackoverflow bug with `detect`, `some`, `every` on large inputs ([#1293](https://github.com/caolan/async/issues/1293)).
+
+# v2.1.0
+
+- `retry` and `retryable` now support an optional `errorFilter` function that determines if the `task` should retry on the error ([#1256](https://github.com/caolan/async/issues/1256), [#1261](https://github.com/caolan/async/issues/1261))
+- Optimized array iteration in `race`, `cargo`, `queue`, and `priorityQueue` ([#1253](https://github.com/caolan/async/issues/1253))
+- Added alias documentation to doc site ([#1251](https://github.com/caolan/async/issues/1251), [#1254](https://github.com/caolan/async/issues/1254))
+- Added [BootStrap scrollspy](http://getbootstrap.com/javascript/#scrollspy) to docs to highlight in the sidebar the current method being viewed  ([#1289](https://github.com/caolan/async/issues/1289), [#1300](https://github.com/caolan/async/issues/1300))
+- Various minor doc fixes ([#1263](https://github.com/caolan/async/issues/1263), [#1264](https://github.com/caolan/async/issues/1264), [#1271](https://github.com/caolan/async/issues/1271), [#1278](https://github.com/caolan/async/issues/1278), [#1280](https://github.com/caolan/async/issues/1280), [#1282](https://github.com/caolan/async/issues/1282), [#1302](https://github.com/caolan/async/issues/1302))
+
+# v2.0.1
+
+- Significantly optimized all iteration based collection methods such as `each`, `map`, `filter`, etc ([#1245](https://github.com/caolan/async/issues/1245), [#1246](https://github.com/caolan/async/issues/1246), [#1247](https://github.com/caolan/async/issues/1247)).
+
+# v2.0.0
+
+Lots of changes here!
+
+First and foremost, we have a slick new [site for docs](https://caolan.github.io/async/). Special thanks to [**@hargasinski**](https://github.com/hargasinski) for his work converting our old docs to `jsdoc` format and implementing the new website. Also huge ups to [**@ivanseidel**](https://github.com/ivanseidel) for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well.
+
+The biggest feature is modularization. You can now `require("async/series")` to only require the `series` function. Every Async library function is available this way. You still can `require("async")` to require the entire library, like you could do before.
+
+We also provide Async as a collection of ES2015 modules. You can now `import {each} from 'async-es'` or `import waterfall from 'async-es/waterfall'`. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size.
+
+Major thanks to [**@Kikobeats**](github.com/Kikobeats), [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for doing the majority of the modularization work, as well as [**@jdalton**](github.com/jdalton) and [**@Rich-Harris**](github.com/Rich-Harris) for advisory work on the general modularization strategy.
+
+Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that:
+
+1. Takes a variable number of arguments
+2. The last argument is always a callback
+3. The callback can accept any number of arguments
+4. The first argument passed to the callback will be treated as an error result, if the argument is truthy
+5. Any number of result arguments can be passed after the "error" argument
+6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop.
+
+There were several cases where Async accepted some functions that did not strictly have these properties, most notably `auto`, `every`, `some`, `filter`, `reject` and `detect`.
+
+Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in `waterfall` and `auto`, there was a `setImmediate` between each task -- these deferrals have been removed. A `setImmediate` call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with `async.ensureAsync()`.
+
+Another big performance win has been re-implementing `queue`, `cargo`, and `priorityQueue` with [doubly linked lists](https://en.wikipedia.org/wiki/Doubly_linked_list) instead of arrays. This has lead to queues being an order of [magnitude faster on large sets of tasks](https://github.com/caolan/async/pull/1205).
+
+## New Features
+
+- Async is now modularized. Individual functions can be `require()`d from the main package. (`require('async/auto')`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996))
+- Async is also available as a collection of ES2015 modules in the new `async-es` package. (`import {forEachSeries} from 'async-es'`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996))
+- Added `race`, analogous to `Promise.race()`. It will run an array of async tasks in parallel and will call its callback with the result of the first task to respond. ([#568](https://github.com/caolan/async/issues/568), [#1038](https://github.com/caolan/async/issues/1038))
+- Collection methods now accept ES2015 iterators.  Maps, Sets, and anything that implements the iterator spec can now be passed directly to `each`, `map`, `parallel`, etc.. ([#579](https://github.com/caolan/async/issues/579), [#839](https://github.com/caolan/async/issues/839), [#1074](https://github.com/caolan/async/issues/1074))
+- Added `mapValues`, for mapping over the properties of an object and returning an object with the same keys. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177))
+- Added `timeout`, a wrapper for an async function that will make the task time-out after the specified time. ([#1007](https://github.com/caolan/async/issues/1007), [#1027](https://github.com/caolan/async/issues/1027))
+- Added `reflect` and `reflectAll`, analagous to [`Promise.reflect()`](http://bluebirdjs.com/docs/api/reflect.html), a wrapper for async tasks that always succeeds, by gathering results and errors into an object.  ([#942](https://github.com/caolan/async/issues/942), [#1012](https://github.com/caolan/async/issues/1012), [#1095](https://github.com/caolan/async/issues/1095))
+- `constant` supports dynamic arguments -- it will now always use its last argument as the callback. ([#1016](https://github.com/caolan/async/issues/1016), [#1052](https://github.com/caolan/async/issues/1052))
+- `setImmediate` and `nextTick` now support arguments to partially apply to the deferred function, like the node-native versions do. ([#940](https://github.com/caolan/async/issues/940), [#1053](https://github.com/caolan/async/issues/1053))
+- `auto` now supports resolving cyclic dependencies using [Kahn's algorithm](https://en.wikipedia.org/wiki/Topological_sorting#Kahn.27s_algorithm) ([#1140](https://github.com/caolan/async/issues/1140)).
+- Added `autoInject`, a relative of `auto` that automatically spreads a task's dependencies as arguments to the task function. ([#608](https://github.com/caolan/async/issues/608), [#1055](https://github.com/caolan/async/issues/1055), [#1099](https://github.com/caolan/async/issues/1099), [#1100](https://github.com/caolan/async/issues/1100))
+- You can now limit the concurrency of `auto` tasks. ([#635](https://github.com/caolan/async/issues/635), [#637](https://github.com/caolan/async/issues/637))
+- Added `retryable`, a relative of `retry` that wraps an async function, making it retry when called. ([#1058](https://github.com/caolan/async/issues/1058))
+- `retry` now supports specifying a function that determines the next time interval, useful for exponential backoff, logging and other retry strategies. ([#1161](https://github.com/caolan/async/issues/1161))
+- `retry` will now pass all of the arguments the task function was resolved with to the callback ([#1231](https://github.com/caolan/async/issues/1231)).
+- Added `q.unsaturated` -- callback called when a `queue`'s number of running workers falls below a threshold. ([#868](https://github.com/caolan/async/issues/868), [#1030](https://github.com/caolan/async/issues/1030), [#1033](https://github.com/caolan/async/issues/1033), [#1034](https://github.com/caolan/async/issues/1034))
+- Added `q.error` -- a callback called whenever a `queue` task calls its callback with an error. ([#1170](https://github.com/caolan/async/issues/1170))
+- `applyEach` and `applyEachSeries` now pass results to the final callback. ([#1088](https://github.com/caolan/async/issues/1088))
+
+## Breaking changes
+
+- Calling a callback more than once is considered an error, and an error will be thrown. This had an explicit breaking change in `waterfall`. If you were relying on this behavior, you should more accurately represent your control flow as an event emitter or stream. ([#814](https://github.com/caolan/async/issues/814), [#815](https://github.com/caolan/async/issues/815), [#1048](https://github.com/caolan/async/issues/1048), [#1050](https://github.com/caolan/async/issues/1050))
+- `auto` task functions now always take the callback as the last argument. If a task has dependencies, the `results` object will be passed as the first argument. To migrate old task functions, wrap them with [`_.flip`](https://lodash.com/docs#flip) ([#1036](https://github.com/caolan/async/issues/1036), [#1042](https://github.com/caolan/async/issues/1042))
+- Internal `setImmediate` calls have been refactored away. This may make existing flows vulnerable to stack overflows if you use many synchronous functions in series. Use `ensureAsync` to work around this. ([#696](https://github.com/caolan/async/issues/696), [#704](https://github.com/caolan/async/issues/704), [#1049](https://github.com/caolan/async/issues/1049), [#1050](https://github.com/caolan/async/issues/1050))
+- `map` used to return an object when iterating over an object.  `map` now always returns an array, like in other libraries.  The previous object behavior has been split out into `mapValues`. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177))
+- `filter`, `reject`, `some`, `every`, `detect` and their families like `{METHOD}Series` and `{METHOD}Limit` now expect an error as the first callback argument, rather than just a simple boolean. Pass `null` as the first argument, or use `fs.access` instead of `fs.exists`. ([#118](https://github.com/caolan/async/issues/118), [#774](https://github.com/caolan/async/issues/774), [#1028](https://github.com/caolan/async/issues/1028), [#1041](https://github.com/caolan/async/issues/1041))
+- `{METHOD}` and `{METHOD}Series` are now implemented in terms of `{METHOD}Limit`. This is a major internal simplification, and is not expected to cause many problems, but it does subtly affect how functions execute internally. ([#778](https://github.com/caolan/async/issues/778), [#847](https://github.com/caolan/async/issues/847))
+- `retry`'s callback is now optional. Previously, omitting the callback would partially apply the function, meaning it could be passed directly as a task to `series` or `auto`. The partially applied "control-flow" behavior has been separated out into `retryable`. ([#1054](https://github.com/caolan/async/issues/1054), [#1058](https://github.com/caolan/async/issues/1058))
+- The test function for `whilst`, `until`, and `during` used to be passed non-error args from the iteratee function's callback, but this led to weirdness where the first call of the test function would be passed no args. We have made it so the test function is never passed extra arguments, and only the `doWhilst`, `doUntil`, and `doDuring` functions pass iteratee callback arguments to the test function ([#1217](https://github.com/caolan/async/issues/1217), [#1224](https://github.com/caolan/async/issues/1224))
+- The `q.tasks` array has been renamed `q._tasks` and is now implemented as a doubly linked list (DLL). Any code that used to interact with this array will need to be updated to either use the provided helpers or support DLLs ([#1205](https://github.com/caolan/async/issues/1205)).
+- The timing of the `q.saturated()` callback in a `queue` has been modified to better reflect when tasks pushed to the queue will start queueing. ([#724](https://github.com/caolan/async/issues/724), [#1078](https://github.com/caolan/async/issues/1078))
+- Removed `iterator` method in favour of [ES2015 iterator protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators ) which natively supports arrays ([#1237](https://github.com/caolan/async/issues/1237))
+- Dropped support for Component, Jam, SPM, and Volo ([#1175](https://github.com/caolan/async/issues/1175), #[#176](https://github.com/caolan/async/issues/176))
+
+## Bug Fixes
+
+- Improved handling of no dependency cases in `auto` & `autoInject` ([#1147](https://github.com/caolan/async/issues/1147)).
+- Fixed a bug where the callback generated by `asyncify` with  `Promises` could resolve twice ([#1197](https://github.com/caolan/async/issues/1197)).
+- Fixed several documented optional callbacks not actually being optional ([#1223](https://github.com/caolan/async/issues/1223)).
+
+## Other
+
+- Added `someSeries` and `everySeries` for symmetry, as well as a complete set of `any`/`anyLimit`/`anySeries` and `all`/`/allLmit`/`allSeries` aliases.
+- Added `find` as an alias for `detect. (as well as `findLimit` and `findSeries`).
+- Various doc fixes ([#1005](https://github.com/caolan/async/issues/1005), [#1008](https://github.com/caolan/async/issues/1008), [#1010](https://github.com/caolan/async/issues/1010), [#1015](https://github.com/caolan/async/issues/1015), [#1021](https://github.com/caolan/async/issues/1021), [#1037](https://github.com/caolan/async/issues/1037), [#1039](https://github.com/caolan/async/issues/1039), [#1051](https://github.com/caolan/async/issues/1051), [#1102](https://github.com/caolan/async/issues/1102), [#1107](https://github.com/caolan/async/issues/1107), [#1121](https://github.com/caolan/async/issues/1121), [#1123](https://github.com/caolan/async/issues/1123), [#1129](https://github.com/caolan/async/issues/1129), [#1135](https://github.com/caolan/async/issues/1135), [#1138](https://github.com/caolan/async/issues/1138), [#1141](https://github.com/caolan/async/issues/1141), [#1153](https://github.com/caolan/async/issues/1153), [#1216](https://github.com/caolan/async/issues/1216), [#1217](https://github.com/caolan/async/issues/1217), [#1232](https://github.com/caolan/async/issues/1232), [#1233](https://github.com/caolan/async/issues/1233), [#1236](https://github.com/caolan/async/issues/1236), [#1238](https://github.com/caolan/async/issues/1238))

+- `each` and family will properly handle an empty array ([#578](https://github.com/caolan/async/issues/578))
+- `eachSeries` and family will finish if the underlying array is modified during execution ([#557](https://github.com/caolan/async/issues/557))
+- `queue` will throw if a non-function is passed to `q.push()` ([#593](https://github.com/caolan/async/issues/593))

+
+No known breaking changes, we are simply complying with semver from here on out.
+
+Changes:
+
+- Start using a changelog!

+
+Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/v3/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm i async`, it can also be used directly in the browser.  An ESM/MJS version is included in the main `async` package that should automatically be used with compatible bundlers such as Webpack and Rollup.
+
+A pure ESM version of Async is available as [`async-es`](https://www.npmjs.com/package/async-es).

+ *
+ * If any of the {@link AsyncFunction}s pass an error to their callback, the `auto` sequence
+ * will stop. Further tasks will not execute (so any other functions depending

+ * error.
+ *
+ * {@link AsyncFunction}s also receive an object containing the results of functions which
+ * have completed so far as the first argument, if they have dependencies. If a
+ * task function has no dependencies, it will only be passed a callback.

+ * @param {Object} tasks - An object. Each of its properties is either a

+ * in the array. The object's key of a property serves as the name of the task
+ * defined by that property, i.e. can be used when specifying requirements for
+ * other tasks. The function receives one or two arguments:
+ * * a `results` object, containing the results of the previously executed
+ *   functions, only passed if the task has any dependencies,
+ * * a `callback(err, result)` function, which must be called when finished,
+ *   passing an `error` (which can be `null`) and the result of the function's
+ *   execution.
+ * @param {number} [concurrency=Infinity] - An optional `integer` for
+ * determining the maximum number of tasks that can be run in parallel. By
+ * default, as many as possible.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback. Results are always returned; however, if an
+ * error occurs, no further `tasks` will be performed, and the results object
+ * will only contain partial results. Invoked with (err, results).

+/**
+ * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
+ * tasks are specified as parameters to the function, after the usual callback
+ * parameter, with the parameter names matching the names of the tasks it
+ * depends on. This can provide even more readable task graphs which can be
+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @see [async.auto]{@link module:ControlFlow.auto}
+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ *   when finished, passing an `error` (which can be `null`) and the result of
+ *   the function's execution. The remaining parameters name other tasks on
+ *   which the task is dependent, and the results from those tasks are the
+ *   arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @returns {Promise} a promise, if no callback is passed
+ * @example
+ *
+ * //  The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ *     get_data: function(callback) {
+ *         // async code to get some data
+ *         callback(null, 'data', 'converted to array');
+ *     },
+ *     make_folder: function(callback) {
+ *         // async code to create a directory to store a file in
+ *         // this is run at the same time as getting the data
+ *         callback(null, 'folder');
+ *     },
+ *     write_file: function(get_data, make_folder, callback) {
+ *         // once there is some data and the directory exists,
+ *         // write the data to a file in the directory
+ *         callback(null, 'filename');
+ *     },
+ *     email_link: function(write_file, callback) {
+ *         // once the file is written let's email a link to it...
+ *         // write_file contains the filename returned by write_file.
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});
+ *     }
+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier.  To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.
+ * async.autoInject({
+ *     //...
