    ### Notable Changes

    #### 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));
    ```

    #### 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')`.

    Contributed by Yagiz Nizipli in [#51476](https://github.com/nodejs/node/pull/51476).

    #### New connection attempt events

    Three new events were added in the `net.createConnection` flow:

    * `connectionAttempt`: Emitted when a new connection attempt is established. In case of Happy Eyeballs,     this might emitted multiple times.
    * `connectionAttemptFailed`: Emitted when a connection attempt failed. In case of Happy Eyeballs, this     might emitted multiple times.
    * `connectionAttemptTimeout`: Emitted when a connection attempt timed out. In case of Happy Eyeballs, this     will not be emitted for the last attempt. This is not emitted at all if Happy Eyeballs is not used.

    Additionally, a previous bug has been fixed where a new connection attempt could have been started after a     previous one failed and after the connection was destroyed by the user.
    This led to a failed assertion.

    #### Permission Model changes

    Node.js 20.12.0 comes with several fixes for the experimental permission model and two new semver-minor     commits.
    We're adding a new flag `--allow-addons` to enable addon usage when using the Permission Model.

    ```console     $ node --experimental-permission --allow-addons     ```

    Contributed by Rafael Gonzaga in [#51183](https://github.com/nodejs/node/pull/51183)

    And relative paths are now supported through the `--allow-fs-*` flags.
    Therefore, with this release one can use:

    ```console     $ node --experimental-permission --allow-fs-read=./index.js     ```

    To give only read access to the entrypoint of the application.

    #### 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.

    ```json     {       main: /path/to/bundled/script.js,       output: /path/to/write/the/generated/blob.blob,       assets: {         a.jpg: /path/to/a.jpg,         b.txt: /path/to/b.txt       }     }     ```

    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');
    ```

    Contributed by Joyee Cheung in [#50960](https://github.com/nodejs/node/pull/50960).

    #### Support configurable snapshot through `--build-snapshot-config` flag

    We are adding a new flag `--build-snapshot-config` to configure snapshots through a custom JSON     configuration file.

    ```console     $ node --build-snapshot-config=/path/to/myconfig.json     ```

    When using this flag, additional script files provided on the command line will     not be executed and instead be interpreted as regular command line arguments.

    These changes were contributed by Joyee Cheung and Anna Henningsen in     [#50453](https://github.com/nodejs/node/pull/50453)

    #### 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, ...).

    ```cjs     const { styleText } = require('node:util');
    const errorMessage = styleText('red', 'Error! Error!');
    console.log(errorMessage);
    ```

    Contributed by Rafael Gonzaga in [#51850](https://github.com/nodejs/node/pull/51850).

    #### 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.
    const script = new Script(       `(async function() {         const { filename } = await import('./test.mjs');
        return import(filename, { with: { type: 'json' } })       })();`,       {         filename: resolve(__dirname, 'test-with-default.js'),         importModuleDynamically: constants.USE_MAIN_CONTEXT_DEFAULT_LOADER,       });

    // { default: { hello: 'world' } }     script.runInThisContext().then(console.log);
    ```
