## 2024-03-06, Version 21.7.0 (Current), @RafaelGSS prepared by @marco-ippolito
### Text Styling
* `util.styleText(format, text)`: This function returns a formatted text considering the `format` passed.
A new API has been created to format text based on `util.inspect.colors`, enabling you to style text in different colors (such as red, blue, ...) and emphasis (italic, bold, ...).
Contributed by Rafael Gonzaga in [#51850](https://github.com/nodejs/node/pull/51850).
### Loading and parsing environment variables
* `process.loadEnvFile(path)`:
* Use this function to load the `.env` file. If no path is specified, it automatically loads the .env file in the current directory. Example: `process.loadEnvFile()`.
* Load a specific .env file by specifying its path. Example: `process.loadEnvFile('./development.env')`.
* `util.parseEnv(content)`:
* Use this function to parse an existing string containing environment variable assignments.
* Example usage: `require('node:util').parseEnv('HELLO=world')`.

### Support for multi-line values for `.env` file
Node.js 21.7.0 will now support multi-line values in the .env file:
```text
MULTI_LINE="HELLO
WORLD"
```

### sea: support embedding assets
Users can now include assets by adding a key-path dictionary
to the configuration as the `assets` field. At build time, Node.js
would read the assets from the specified paths and bundle them into
the preparation blob. In the generated executable, users can retrieve
the assets using the `sea.getAsset()` and `sea.getAssetAsBlob()` API.
The single-executable application can access the assets as follows:
```cjs
const { getAsset } = require('node:sea');
// Returns a copy of the data in an ArrayBuffer
const image = getAsset('a.jpg');
// Returns a string decoded from the asset as UTF8.
const text = getAsset('b.txt', 'utf8');
// Returns a Blob containing the asset without copying.
const blob = getAssetAsBlob('a.jpg');
```

### vm: support using the default loader to handle dynamic import()
This patch adds support for using `vm.constants.USE_MAIN_CONTEXT_DEFAULT_LOADER` as the
`importModuleDynamically` option in all vm APIs that take this option except `vm.SourceTextModule`. This allows users to have a shortcut to support dynamic `import()` in the compiled code without missing the compilation cache if they don't need customization of the loading process. We emit an experimental warning when the `import()` is actually handled by the default loader through this option instead of requiring `--experimental-vm-modules`.
```js
const { Script, constants } = require('node:vm');
const { resolve } = require('node:path');
const { writeFileSync } = require('node:fs');
// Write test.js and test.txt to the directory where the current script
// being run is located.
writeFileSync(resolve(__dirname, 'test.mjs'),
'export const filename = "./test.json";');
writeFileSync(resolve(__dirname, 'test.json'),
'{"hello": "world"}');
// Compile a script that loads test.mjs and then test.json
// as if the script is placed in the same directory.

### crypto: implement crypto.hash()
This patch introduces a helper crypto.hash() that computes
a digest from the input at one shot. This can be 1.2-2x faster
than the object-based createHash() for smaller inputs (<= 5MB)
that are readily available (not streamed) and incur less memory
overhead since no intermediate objects will be created.
```js
const crypto = require('node:crypto');
// Hashing a string and return the result as a hex-encoded string.
const string = 'Node.js';
// 10b3493287f831e81a438811a1ffba01f8cec4b7
console.log(crypto.hash('sha1', string));
```
